Description of the invention (2) The vertical axis of the board is symmetrical. When the reflector is used in a reflective liquid crystal display device, light is reflected / diffused in all directions, including a direction independent of the viewing angle of the user. In other words, such a reflection type liquid crystal display device cannot make full use of incident light. In many cases, a reflection type liquid crystal display device is used as a display part of a mobile communication device. In many cases, "input pen" (a pen input device for inputting data into a pen-based input system) is adopted as a mechanism for inputting data. When the user inputs data via the input pen, the display screen is depressed due to the pressure applied by the user via the input pen. The liquid crystal layer in the display panel is partially flattened, and the image on the display is disturbed. To solve these problems, a polymer matrix may be provided in a liquid crystal layer between a pair of substrates to support the liquid crystal element. However, it is difficult to arrange the polymer matrix into a desired pattern, so some of the polymer matrix may not be located in the pixel area unexpectedly, thereby reducing the contrast of the display.

Description of Invention (Π). Fig. 75 is a sectional view showing the structure of a reflective liquid crystal display device according to a modification of the twenty-seventh embodiment. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below by way of illustration with reference to the accompanying drawings. (Embodiment 1) FIG. 1F is a sectional view showing a reflector 15 according to Embodiment 1 of the present invention. The reflector 15 includes a photoresist convex portion 12c on a glass substrate u. A metal thin film 14 is provided to cover the concave portion 12c and the glass substrate u. The manufacturing method of the reflector 15 will now be described with reference to circles 1A to 1F. First, as shown in FIG. 1A, a photoresist material (for example, " 〇FPR_80〇 ": T〇ky〇〇hka K〇gy〇C〇, preferably at about 500 to 3000 revolutions per minute, Ltd.) was transferred onto one surface of a 1.1-mm-thick glass substrate (e.g., " 7059 ": Corning Industries). In this example, the photoresist material is applied to the substrate at about 3000 rpm for about 30 seconds to form a photoresist film 12a with a thickness of about 0.5 micrometers on the glass substrate. Printed by Zhengong Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs (please read the notes on the back before filling out this page) The substrate is pre-baked at about 100 ° C for about 30 minutes. Then, it will be included as shown in 囷 2 A photomask 13 of a plurality of semicircular light-shielding regions at arbitrary positions is placed on the broken glass substrate 1 丨 as shown in FIG. 1B. Subsequently, the substrate is exposed and a developing solution (for example, NMD_3: T〇ky〇〇hka Kogyo Co., Ltd.) (2.38%). Therefore, as shown in FIG. Ic, the unexposed portion of the photoresist film 12a forms a micro-semi-circular portion 12b on the glass substrate U. Note that it is represented by a small rectangular box in FIG. 1B The light-transmitting area in the photomask 13. When viewed from above, the shape of each small semi-circular portion 12b on the glass substrate ^ -16-The size of the private paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm at the center of the Ministry of Economic Affairs) Printed by the Bureau of Standardization, Shellfish Consumer Cooperative A7 ___B7 5. The description of the invention (Η) corresponds to the light-shielding area in the photomask 13 shown in Fig. 2. Subsequently, as shown in Fig. 1D, the substrate is inclined so that each semicircular portion i2b The diameter of the side is lower than its edge. In this example, the substrate was inclined at 90 °. The inclined substrate was heat-treated at about 120 to 25 ° C. In this example, the substrate was heat-treated at about 250 ° C for 30 minutes. As a result, as shown in FIG. 1E, The surface of the semi-circular portion 12b becomes smooth and rounded to form an asymmetric convex portion 12c »As described in detail below, the inclined distribution of the asymmetric convex portion 12c is deviated. Then the substrate is slowly cooled and bent. When viewed from the normal of the substrate (ie, front view), each asymmetric convex surface portion 12c has a semi-circular shape due to the influence of the pattern of the photomask 13. As shown in FIG. 1E, the diameter of the asymmetric Λ surface portion 12c (below) ) The side is thicker than the arc_side. The asymmetrical product. The vertical section of the surface portion 12c is curved at the upper edge. Then, as shown in 囷 1F, a metal thin film 形成 is formed on the entire surface of the reflector 15. Eight can be used. 1. Oil, € 1, and other metals are used as the metal thin film 14. The metal thin film 14 is about 0.01 to 1.0 micron thick. In this example, the metal thin film 14 is formed by the evaporation of the air of A1. Thus, a reflector 15 is obtained. Note that Figure 1F corresponds to A cross-sectional view of the asymmetric convex portion 12c of the reflector 15 obtained in the direction of the A-A1 line. 囷 3A shows the inclined distribution of the surface of the aforementioned reflector 15. Here, the surface of the reflector 15 is inclined between the surface of the substrate u and the convex portion The angle between the tangent lines on the surface of 12c. The oblique distribution is measured in a direction perpendicular to the diameter side of the asymmetric & surface portion 12c using an interference microscope to measure β Figure 3B is taken along the direction corresponding to the line AA · in Figure 2 A cross-sectional view of an asymmetric convex portion 12c. In FIG. 3B, between the surface of the substrate 11 and the asymmetry, the national standard (CNS) (21GX 297 male f) is applied --- --------- ¢ ------ 1T (Please read the precautions on the back before filling out this page) A7 B7 Printed by the Central Procurement Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, V. Invention Description (! 5) The angle α between the tangent to the surface of the surface portion 12c is represented by + α when the tangent is inclined clockwise with the substrate, and is represented by .α when the clock is inclined counterclockwise from the substrate surface. It is assumed that the measurements in this manual are performed in this way. As shown in FIG. 3A, the inclination distribution of the convex portion of the reflector 15 is biased. FIG. 4 is a flowchart showing a method of measuring the reflection characteristics of the reflector 15. It is assumed here that the reflector 15 is housed in a liquid crystal display device. It is desirable that the liquid crystal display device in which the reflector 15 is housed includes the reflector 15 as a lower substrate, an upper glass substrate 53 and a liquid crystal layer interposed therebetween. The reflector 15 is arranged such that the convex portion thereof is in contact with the liquid crystal layer. The refractive indices of the liquid crystal layer and the glass substrate 53 are both about 1.5. For the measurement, the liquid crystal layer was replaced with a UV curable adhesive 52 having a refractive index of about 15 which was substantially the same. The reflector 15 is adhered to the upper glass substrate 53 using an adhesive 52 to form an element. The light 55 emitted from the light source 54 is incident on the element in the direction normal to the substrate 53. The incident light 55 is reflected by the reflector 15; the intensity of the reflected light 56 is measured by the photomultiplier tube 57 in a direction inclined from the substrate normal. The reflection characteristics of the reflector 15 were measured. Figure 5 shows the reflector reflection characteristics obtained from the measurement results. The x-axis represents the measurement angle of the photomultiplier tube 57 with respect to the substrate normal, and the y-axis represents the intensity of the reflected light 56. In FIG. 5, the dots indicate the reflection characteristics of the reflector 15 of Embodiment 1 of the present invention, and the square dots indicate a standard whiteboard of MgO (magnesium oxide). In Figure 5, the intensity of the reflected light is standardized, and the reflected light intensity of the normal whiteboard in the normal direction is 10 • 18 · This paper is A degree applicable to the Chinese National Standard (CNS) 8 4% grid (210X297 mm) 5ΓΤ- · -β (Please read the precautions on the back before filling this page} A7 B7 Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (ΐδ) As shown in Figure 5, the reflected light intensity of the standard white board (Indicated by dots) are substantially the same (and low) in any viewing direction. On the other hand, the reflector 15 (indicated by dots) of Example 1 is about · 30 to +5. The tilt range (from the substrate normal) Within (especially within a slant range of about -25 to 0.) has a high reflected light intensity. It is also determined that the interface between the reflector 15 and the actual liquid crystal layer has the same result. As shown in FIG. 6, when light from the reflector normal When incident on the reflector, the concave / convex portion of the reflector 15 reflects light to a specific direction (within the viewing angle) to produce a high-brightness display image. Moreover, when the shape of the concave / convex portion reflects the incident light to In the directions of Figures 7 and 8, When light and the substrate normal are incident on the reflector obliquely, a high-brightness display image is observed from a viewing angle. In order to deflect the angular distribution between the substrate surface and the surface of the convex portion, the substrate is maintained during heating in Example 丨The invention is not limited to this case. For example, 'the hot air may be applied to the semicircular portion 12b on the substrate, or the substrate may be rotated to generate a centrifugal force on the semicircular portion 12b on the substrate. (Example 2) Embodiment 2 of the present invention provides a method for forming a reflector into a desired shape without any heat treatment. Now, a method for manufacturing the reflector 22 in Embodiment 2 will be described with reference to FIGS. 9A to 9F. First, as shown in FIG. 9A, At preferably about 500 to 3000 revolutions per minute, the photoresist material (for example, " 〇FPR_80〇 ": T〇ky〇〇hka K〇gy〇c〇,

Note that the light-transmitting region in the photomask 13 is represented by a small rectangular block in FIG. 9B. The shape of each of the small semicircular portions 12b on the glass substrate ^ corresponds to the light-shielding region in the photomask 13 shown in FIG. Subsequently, as shown in FIG. 9D, the glass substrate 11 radiates the electron beam 21 from the arc edge of the semicircular portion 12b in a direction inclined from the surface of the substrate. Ion beams are generated using methods such as ion-milling. As a result of irradiating the ion beam 21, the portion of the glass substrate 11 that does not cover the semicircular portion 12b is removed. On the other hand, the portion of the glass substrate 11 covered with the micro-semi-circular portion 12 is not removed until the micro-semi-circular portion 12b for protecting these portions is completely removed. As a result, the shape of the 'glass substrate 11 becomes anisotropic as shown in Fig. 9E, in which an asymmetric concave portion 11c is formed around the portion of the glass substrate 11 covered with the micro-semicircular portion 12b. The diameter of the formed concave portion lie is shallower on one side than the other. The vertical section of the symmetrical concave portion 11c is curved at the lower edge. Thereafter, as shown in FIG. 9F, a metal thin film 14 is formed on the entire cross-section surface of the reflector 15.

Description of Invention (I9) A concave / convex layer of a photoresist material is formed on the upper layer 148 ^ As Example 1 The twisted surface portions 148 a of the symmetrical convex portion are located on the surface of the upper layer of the concave / convex layer 148. The metal thin film 147 which is a part of the reflector is located on the surface portion 148a of the concave / convex layer 148. The metal thin film H7 located on the convex portion 148a is used as a pixel electrode in this example. The convex portion 14 and the metal thin film 147 have the same function as the reflector 15 of the first embodiment. The β contact hole penetrates the concave / convex layer 148 to be located on the drain 150a of the TPT 150. The drain electrode 150a is electrically connected to the pixel electrode 147 on the concave / convex layer 148 via a contact hole. Therefore, the TFT panel substrate 149 has pixels with a passive structure. The alignment film 146 is located on the TFT panel substrate 149 on the side of the liquid crystal layer 145. The concave / convex layer 148 of the aforementioned metal thin film is formed by the method of the first embodiment. The arrangement of the convex portions 148a of the concave / convex layer 148 is shown in FIG. As shown in Fig. 13, the convex portions 148a are aligned in the same orientation (i.e., the diameter sides are parallel to each other). Because of this configuration, the concave / convex layer 148 directs most of the reflected light toward a specific viewing angle. The configuration of the concave / convex layer 148-in which the diameter of the convex portion 148a is located in the same orientation-can also be applied to the foregoing embodiment 2 and the following embodiment 4 to obtain the same effect. On the top glass substrate 141 are a color filter 142, a transparent conductive film 143, and an alignment film 144. The color filter 142 includes a light shielding portion 142b-which is located on the TFT 150-and a color filter portion 142a. The glass substrate 141 is connected to the TFT panel substrate 149 * and a liquid crystal material is injected therebetween to form a liquid crystal layer 145.

Because of the pair of palm drugs, the twisted pitch (PO) of the liquid crystal molecules is set to 5 micrometers, and the thickness d of the liquid crystal layer 145 is set to about 4.5 micrometers due to the spacer. Therefore, d / pO 値 is set to about 0.9. The alignment films 144 and 146 are formed of polyimide. The alignment methods used by the alignment films 144 and 146 are set to be opposite to each other. Therefore, the orientation of the liquid crystal is 360 between the substrates 141 and 149. Torsion (rotation). The reflection type liquid crystal display device of Example 3 having such a structure displays an image according to the operation principle which is substantially the same as the white-tailor type host-guest type liquid crystal display device. Further, since the convex portion 148a of the concave / convex layer 148 has a uniform orientation as shown in Fig. 13, the liquid crystal display device of the third embodiment shifts the direction of diffusion of incident light. Therefore, when this kind of liquid crystal display device is actually applied, the reflected light will not be deflected to a direction irrelevant to the user's viewing angle, but mainly directed to the user's viewing angle. Therefore, a reflection type liquid crystal display device having a high-brightness display is obtained.

Mm thick glass substrates (such as " 7059 " · Corning Industries) U. In this embodiment, the glass is rotated at about 500 revolutions per minute When the substrate is ^, a photoresist material is applied to the surface for about 20 seconds to form a photoresist film 12a with a thickness of about 2 microns on the glass substrate. The substrate is pre-baked at about 100 ° C for about 30 minutes. Then, as shown in FIG. 14B, electron beam exposure 60 was used to irradiate the electron beam eb onto a small area (about 0.05 micrometer diameter in this example) of the photoresist film 12a. Therefore, on the glass substrate 11 The specific shape of the convex portion 31 will be described below with reference to FIGS. 16A and 16B. Printed by the Consumers' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 11 As shown in Figure 15, the electron beam exposure 60 includes the main components of the electron beam source 61, condenser lens 62, pinhole 63, projection lens 64, and deflection diagram 65. The main component, support mechanism, and photoresist film 12a of the electron beam EB to be radiated are located in the sky. The electrons emitted from the electron beam source 61 are accelerated by the potential difference, and the condenser lens 62 is used. Concentrated on the pinhole 63. The electron passes through the pinhole 63 and is then concentrated on a point on the photoresist film 12a by the projection lens 64. The electron path can be deflected under control by applying a current through the deflection coil 65. Therefore The incident electron beam can be controlled in a specific area of the photoresist film 12a. Moreover, the depth of photoresist removal can also be controlled by controlling the amount of radiation of the electron beam EB. Therefore, the formed after exposure to the electron beam EB The shape of the photoresist film 12a can be two-dimensionally controlled by controlling the direction and amount of electron beam radiation. FIGS. 16A and 16B are each a plan view showing the shape of the convex portion 31 formed in Example 4, and along FIG. 16A Shown A cross-sectional view of the bisector of the inner corner of the fan shape. Figure-24 · This paper size applies to the Chinese National Standard (CNS > Α4 size (210X297 mm)) Printed by the Consumer Cooperative of the Central Government Bureau of the Ministry of Economic Affairs A7 B7 5. Description of the invention (22) As shown in 16A, each convex portion 31 has a fan shape with an internal angle of about 60 °. As shown in FIG. 16B, the inclined portions of each convex portion 31 have a quadratic curve. It is partially thick. After that, as shown in FIG. 14D, a metal thin film 14 is formed on the entire surface of the substrate 11. For the metal thin film 14, Al, Ni, Cr, Ag, or the like can be used. The metal thin film 14 is preferably about 0.01 to 1.0 micron thick. In this example, the metal thin film 14 is formed by the hollow evaporation of A1 to obtain the reflector 32. FIG. 17 shows the inclined distribution of the surface of the reflector 32, which is observed along the bisector of the inner angle of the fan shape of the convex portion 31; and FIG. 18 shows the reflection specificity of the reflector 32, which is the implementation shown in FIG. 4 example! Measured result. As shown in FIGS. 17 and 18, the reflector 32 of Embodiment 4 ranges from about -30 to +10. It has a high reflected light intensity in the tilt range. Especially about _25 to 0. Within the range of the inclination ', the exemplified bright display can be observed, which is even brighter than the reflector of the embodiment 1 or 2. The reason for obtaining such a reflection characteristic is that the reflector 32 has a fan-shaped convex portion, and more diffused light is deflected forward, while reducing the amount of laterally diffused light. Although Embodiment 4 adopts a fan shape with an internal angle of about 60 °, the present invention is not limited to this. For example, the angle at which the incident light is diffused can be controlled by adjusting the inner angle of the convex portion of the fan shape to be narrower or wider. Further, a concave / convex portion as shown in Figs. 23A to 23F is formed on the reflector. As long as each convex portion has at least one axis on the surface of the substrate, a similar effect can be obtained, in which the distribution of the tilt measured along the axis is zero relative to the axis. The tilt point is asymmetric (for example, Figures 3A, 10, and 17), and all the concave parts are -25- This paper size uses the Chinese National Standard (CNS) M specification (210X297 mm) --------- .Installation ------ Order < Please read the precautions on the back before filling this page) A7 B7 V. Description of the invention (23) --- The average convex part of the invention also has this axis. Here, the average convex portion is divided into imaginary convex portions having an average surface shape of all convex portions on the reflector. Instead of forming the convex portion 31 of the fourth embodiment, the reflector 32 may also be scraped to form a concave portion having a fan shape in the reflector 32, as shown in Figs. 23A to 23F and the like. (Comparative Example) The reflector of the comparative example, the method of manufacturing the reflector, and the reflection characteristics of the reflector will be described below. A method of manufacturing the reflector 14m of the comparative example will now be described with reference to circles 19A to 19E.

One millimeter-thick glass substrate (e.g. " 7059 ": Corning Industries) 111. In the comparative example, the photoresist material was rotated at about 1,000 revolutions per minute and the glass substrate 111 was applied on the surface for about 30 seconds to form a photoresist on the glass substrate. Thin film 112a. The substrate is pre-baked at about 100 ° C for about 30 minutes. Subsequently, a photomask 113 having a miniature circular light-shielding region (see FIG. 20) is placed on the glass substrate 111, as shown in FIG. 19B. After that, the substrate was exposed and developed with a developing solution (NMD-3: Tokyo Ohka Kogyo Co., Ltd.) (2.38%). Therefore, as shown in FIG. 19C, a micro-round portion 112 b is formed on the glass substrate 111. The substrate including the micro-round portion 112b is then heat-treated at preferably about 120 to 250 ° C. In the comparative example, the substrate is heat-treated at about 180 ° C for 30 minutes. As a result, as shown in FIG. 19D, the pattern part 112b -26-this paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) I Off!

The surface of the invention description (24) becomes smooth and round, forming a convex portion 112c with a smooth surface. The substrate is then cured. Next, as shown in FIG. 19E, a metal thin film 114 is formed on the entire surface of the reflector 141. For the metal thin film 114, Ai, So, cr, Ag, or the like can be used. The thickness of the metal thin film 114 is preferably about 0 to about 1 μm. In the comparative example, the metal thin film 114 is formed by the hollow evaporation of A1. And the reflector 141 is obtained.囷 21 shows the inclination distribution of the surface of the reflector 141 of the comparative example, and FIG. 22 shows the reflection characteristic of the reflector 141 'as the measurement result of Example 1 shown in FIG. As shown in FIG. 21, the slope distribution is substantially zero. The tilt points are symmetrical. As shown in FIGS. 21 and 22, the reflector 141 of the comparative example is only about ˜10 to +10. The narrow viewing angle has high reflection intensity, and extremely bright display can be observed at this angle. However, this viewing angle essentially corresponds to the normal direction of reflection, in which light from an undesired image (such as an object located in the panel environment) is reflected on the panel surface. Therefore, it is difficult to observe the display from this direction in actual use. In addition, from a direction other than the viewing angle of about -10 to + 10 °, only a dark display can be observed. As a result, the liquid crystal display device using the reflector 141 can display only a dark image.

In the description of the invention (26) 5, the metal thin film 214 is formed by the empty evaporation of A1, and Obtaining the reflector 215 ° 囷 25 is a flowchart showing a method for measuring the reflection characteristics of the reflector 215. It is assumed here that the reflector 215 is housed in a liquid crystal display device. A known liquid crystal display device including a reflector 215 includes a reflector 215 as a lower substrate, an upper substrate 217, and a liquid crystal layer interposed therebetween. The reflective layer of the reflector 215 is in contact with the liquid crystal layer. The refractive index of the liquid crystal layer and the glass substrate 217 is set to about 1.5. During the measurement, a UV-curable adhesive having substantially the same refractive index as about 1.5 was used in place of the liquid crystal layer. The adhesive 211 is used to adhere the reflector 217 to the upper glass substrate 217 to form a component, as shown in FIG. 26. As shown in FIG. 25, the light from the light source 222 is adjusted to be incident on the element in a direction normal to the substrate. As detailed in 囷 26 (section view of the element taken along the line DD 'of FIG. 25), the light 218 incident on the reflector 215 is reflected by the reflector 215 at an angle 220. The photomultiplier tube 221 is used to receive the reflected light 219 from the element at the angle 220 to measure the intensity of the reflected light 219. As shown in Fig. 25, the photomultiplier tube 221 rotates around the incident point of the light 218, and the reflection angle 220 of the reflected light 219 to be received by the photomultiplier tube 221 remains fixed. During the measurement, the component was fixed, and the light intensity from the light source 222 and the tilt of the photomultiplier tube 221 with respect to the substrate normal (ie, the angle 220) were kept constant. Here, the measurement is performed at an angle 220 of about 50 ° to the substrate normal.囷 28 shows the reflection characteristics of the reflector 215 of Example 5, which is the aforementioned measurement result. The X · axis in FIG. 28 indicates the measurement direction of the photomultiplier tube 221 to measure the intensity of the reflected light 219.

As shown in FIG. 28, The reflector 141 of the comparative example has substantially the same intensity of reflected light in any direction. On the other hand, the reflector 215 of Example 5 has two light intensity spikes at a direction of about 0 ° and about 180 °. Brightness display. There are also two lower light intensities at about 90 ° and about 270 °. Only a dark display can be observed here. (Embodiments 6 to 16) In each of Examples 6 to I6, the reflectors formed by the manufacturing method shown in FIGS. 24A to 24E of Embodiment 5 are used to reflect the reflection characteristics of each of the formed reflectors as shown in FIG. 25 Measuring method: Printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives-IIII — ^ I · I— mnmm X (Please read the precautions on the back before filling this page) Figures 29A and 29B show the light used in Example 6.

As shown in the foregoing appendix, the reflectors of Examples 6 to 16 each have a peak of reflected light intensity in a specific direction. A high-brightness display can be observed here, and a peak of low-reflected light is also observed in other directions. Only a dark display can be seen here. . The reflectors of Examples 6 to 16 have various reflection characteristics. The reflector can deflect the reflected light to a specific direction according to the shape of the concave / convex portion to strengthen the reflected light in a specific direction. Therefore, a very bright display can be obtained in a specific direction. (Embodiment 17) Figures 51A and 51B are diagrams illustrating a reflection type liquid crystal display device of Embodiment 17 using a reflector of the present invention. In many cases, a reflection type liquid crystal display panel or the like as a mobile communication device uses a configuration shown in Fig. 51A or 51B. Fig. 51A illustrates a case where the liquid crystal display panel is placed on a table or the like during use. As shown in FIG. 51A, assuming that the light is incident on the display panel in a direction perpendicular to the desktop on which the display panel is placed (that is, a direction perpendicular to the display panel), the user is biased toward the lower side of the display panel from the normal direction of the panel.

Description of Invention (29) 51B describes the situation where the display panel is held in the user's hands during use. As shown in FIG. 51B, assuming that the light is incident on the display panel in a direction perpendicular to the desktop on which the display panel is placed, the user observes the reflected light from the direction normal to the panel toward the side of the display panel. Therefore, the reflective liquid crystal display panel as the display part of the mobile communication device needs to provide the reflective characteristics shown in FIG. 52, in which the upper and lower sides of the display panel are relatively bright. The display panel has a relatively dark area on the left and right sides, which is not a serious problem. For example, Embodiment 5 photomask 213 can be used to form a concave portion on a reflector substrate, which suitably provides the reflection characteristics shown in Fig. 52. As shown in FIG. 28, the reflector of Example 5 ranges from about 0 to 180. In the direction, a relatively bright area is provided, that is, the upper and lower sides of the display panel, and about 90 and 27. Provides a rather dark area in the direction, that is, the left and right sides of the display panel. Therefore, it can meet the requirements of a display panel as a display part of a mobile communication device or the like. (Embodiment 18) Figure 53 is a diagram illustrating a reflection type liquid crystal display device using a reflector of the present invention in Embodiment 18. In many cases, the LCD panel and other items in a desktop or palmtop (handheld) computer are placed on a table or the like when used, as shown in Figure 53. As shown in 囷 53, assuming that the light is incident on the display panel from the normal direction of the desktop ', the user only observes the reflected light in the direction from the normal direction of the panel toward the upper side of the display panel. Therefore, the liquid crystal display panel needs to provide the reflection characteristics shown in Fig. 54, and only -32- this standard is suitable for financial standards (CNS) A4 · (210X297 mm) ---: --- 1___i______T U3.,?

Description of the invention (30) There is a relatively bright area on the upper side of the display panel. For example, the photomasks of Embodiment 7 or 15 (each shown in Figs. 31A, 31B, 47A, and 47B) can be used to fabricate a concave portion on a reflector to appropriately provide the reflection characteristics shown in Fig. 54.

Description of the Invention (31) The display electrodes 2a formed in a long shape are arranged in parallel, so that when the substrates 1 & lb are connected to each other, the display electrodes 2a intersects with the display electrode 2b located on the upper substrate lb, as shown in FIG. 55C. The area A in which the display electrodes 2a and 2b overlap is used as a pixel portion. An alignment film 3a is formed on the display electrode 2a, and then a rubbing treatment is performed if necessary. As the alignment film 3a, the same material as that of the alignment film 3b is used. Fig. 55B is a plan view showing 6 layers of a display medium sandwiched between substrates 1 & The display medium 6 includes a liquid crystal material 6a and a polymer wall 6b. The reflective liquid crystal display device of this example provides a display by applying a voltage across the display electrodes 2a and 2b to change the orientation of the liquid crystal molecules of the liquid crystal material 6a located in the pixel portion according to the voltage, to provide a display. As the liquid crystal material 6a, a liquid crystal material having an appropriate display mode such as a TN display mode, an STN display mode, or the like can be used. The polymer wall 6b is a wall-like rigid structure of a polymer material, which is used to isolate the pixels and adhere the substrates la and lb. Other components such as sealing elements are not shown in Figs. 55A and 55B. A method for producing a display medium will now be described. First, a mixture of the liquid crystal material 6a and the photopolymerizable precursor is injected into the liquid crystal element by arranging the substrate 1b and the reflector including the substrate 1a and the reflection pattern 5 so as to face each other. In terms of the reactivity and solubility of the liquid crystal material, a monomer containing an acrylate or a methacrylate is used as a photopolymerizable precursor. In addition, appropriate proportions of bifunctional resin and monofunctional resin are added to adjust the polymerization rate and solubility. After the mixture is injected into the element, the element is selectively irradiated with UV rays using a photomask. Normal photomasks of metal and other materials can be placed on the substrate of the component 11} -34- Zhang scale is applicable to China National Standard (CNS) A4 specification (210X297 mm) '~~-.

Invention Description (32). Alternatively, to facilitate the manufacturing method, the display electrodes 23 and 2b may be used to generate a UV-ray intensity distribution. According to the intensity distribution of UV rays, the polymerizable precursors are polymerized only in the region subjected to strong UV rays to obtain a step-like form. In this example, UV irradiation is performed using the display electrodes 2a and 2b as masks. 5a to 56C, UV irradiation in this example will be described. Fig. 56A is a plan view showing an element in which the substrates ia and ib are bonded to each other; and Figs. 56B and 56C are diagrams illustrating UV rays incident on the element from the upper substrate α side. As shown in FIG. 56B, in the pixel region A, the display electrode 2b and the display electrode 2a overlap. The UV light entering the element from the upper substrate lb passes through the transparent film serving as the display electrode three times to reach a mixture 6 of liquid crystal material and photopolymerizable precursor, that is, it passes through the display electrode 2b, and passes through the display electrode 23 twice. On the other hand, in the "B area", only the display electrode 2a is placed. Therefore, the UV light passes through the transparent film only once, and reaches the mixture of the liquid crystal material and the photopolymerizable precursor. Similarly, as shown in FIG. 56C, only the c region has a display electrode 2b on the upper substrate u, and there is no display electrode in the D region. Therefore, the number of times that the UV light entering the device from the upper substrate lb passes through the transparent films in the C and D regions is 1 and zero, respectively. In this way, the UV light reaching the mixture of photopolymerizable precursors of the liquid crystal material has an intensity distribution according to the number of times the UV light passes through the transparent film. Therefore, the minimum intensity of UV light is obtained in the A region, and the highest intensity of UV light is obtained in the D region. Because of the poor irradiation intensity, a polymer wall 6b can be formed, which forms a polymer matrix. The liquid crystal display panel may be heated or gradually cooled to facilitate phase separation of the composition. Because it includes the reflector of the metal thin film 5, the reflective liquid crystal of Example I9-35- This paper size applies to the Chinese National Standard _ (CNS) A4 specification (210X2.97 mm) I 1 ^ —!-1 ^ — ^^ 1 I- n II—- 1 ^ 1 I--. ^^ 1 (Please read the notes on the back before filling out this page) Imprint A7 by Shellfish Consumer Cooperative, Central Bureau of Standards, Ministry of Economic Affairs _____ B7_ V. Description of Invention (33 ) The display device effectively reflects incident light. Moreover, because of the polymer wall 6b, the reflective liquid crystal display device can also fully withstand pressure. Therefore, this reflective liquid crystal display device is extremely suitable as a mobile communication device or the like. The application improvement method of Embodiment 19 will now be described. In Embodiment 19, the metal thin film 5 as a part of the reflector is formed to cover the entire surface of a photoresist layer (not shown) on the lower substrate la. However, the metal thin film 5 may be patterned to correspond to a pixel portion, as shown in FIG. 57A. In this case, the patterned metal thin film 5 can be used as a mask when the display medium is illuminated with light for phase separation. The polymer 6b can be easily and accurately formed. In addition, the patterned metal film 5 portions 5a each corresponding to a pixel portion are electrically connected to each other, as shown in 57A and 57B. If the metal film is located below the display-like electrode ', a capacitance is usually generated between the metal film and the display electrode to change the dielectric constant between pixels and make the display uneven. However, by electrically connecting the portions 5a of the patterned metal film 5 to each other, the potential becomes uniform as shown in Figs. 57A and 57B, so that the display quality on the entire Zhao display panel becomes uniform. Alternatively, the patterned metal thin film including parts 5a in the same column or in the same row may be electrically connected to each other, as shown in FIG. 57C, and the display electrodes of the row or column are extended as a whole. In this case, 'the display electrode 2a formed of a transparent material or the like and the insulating film of the metal thin film 5 which isolates the display electrode 2a in Embodiment 19 may be omitted; and the row or column portion 5a of the metal film is used to apply a voltage to the display medium 6 And the display electrode 2b. In this improved method, a region where the display electrode 2b overlaps with the portion 5a of the formed metal film 5 corresponds to a pixel portion. Moreover, in this improved method, the patterned metal film has been partially 5-36- This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page } ** · * ----- I --- * Gen ------ Ding ____, ··-.. ... 5 i --- ------ Central Bureau of Standards, Ministry of Economic Affairs Employee's consumer cooperation Du printed A7 B7 Five 'Invention Description (34)' ~-It can be used as a mask when UV light hits the lower substrate ia, as shown in the figure. Therefore, in order to reduce the adverse effect of the connecting portion 5b Each connection has formed the pattern I metal film adjacent portion 5 & when forming the polymer lining, the width of the connection portion 连接 used to connect the adjacent two portions 53 is narrower than that of the I connection portion 5b also formed of a metal material. The outside of the connection portion may be formed of a transparent material. In the reflective liquid crystal display device of Embodiment 19, a plurality of transparent films as display electrodes are formed on the upper and lower substrates, so that the display electrodes on one substrate are located on the other substrate. The display electrodes on the substrate are crossed. Alternatively, multiple signals can be formed on each substrate, so that the signals on one substrate can be formed. The wires intersect with the signal lines on another substrate, and multiple switching elements are provided as pixel regions for each overlapping region. As for the switching elements, MI elements each having a metal insulator-metal structure may be used. Alternatively, A plurality of pixel electrodes and counter electrodes arranged in a matrix are individually formed on the substrate. In this case, a plurality of switching elements such as TFTs are provided for each pixel electrode. (Embodiment 20) Embodiment 20 provides an input system, Including a reflective liquid crystal display device used as a display 'and a pen or pen-like element used as an input device (hereinafter, this input system is referred to as a pen-based input system for short). First,' manufacturing a reflective liquid crystal display device ' A pair of substrates includes a substrate of a reflector.

The invention description (35) is shown. Therefore 'Each row of A1 film parts are used as display electrodes. In this example, the reflection The device is designed to incline from the panel normal to the lower side of the panel by about -10. It provides a bright display in a direction of 30 °. The "bottom side" here means the side located at 6 o'clock The "side" means "the side located at 12 o'clock". Subsequently, a plurality of parallel strips of transparent material such as ITO to SnO are formed on a transparent substrate to manufacture a counter substrate.

A7 B7 V. Description of the invention (37) Heating the LCD display panel to about 100 ° C, and irradiating UV rays from the side of the substrate including the reflector (Light intensity: about 8 milliwatts, wavelength: about 365 nanometers) After about 200 seconds. Because the matrix-type A1 film is formed so that each portion corresponds to a pixel portion, as described above, polymerization is started in a region surrounding the pixel portion to form a polymer step. Note that the connecting portion of the formed A1 portion has a width as narrow as possible. Therefore, the connecting portion has substantially no effect on the polymerization. Subsequently, the liquid crystal display panel is slowly cooled (about _6 t / hour) in the furnace. When the panel temperature reaches about 20 * C, remove the display panel from the furnace. Thereafter, the liquid crystal display panel irradiates light from the side of the substrate (light intensity: about 8 mW 'wavelength: about 365 nm) for about 600 seconds to terminate the polymerization. Thus, a liquid crystal display panel is obtained in which a polymer wall surrounds the liquid crystal portion Lc, as shown in FIG. 58C. The liquid crystal portion LC corresponds to the pixel portion, and the liquid crystal molecule orientation in the liquid crystal portion Lc is twisted between the substrates by 24 °. . The orientation of liquid crystal molecules may be partially milky. In this case, the liquid crystal display panel is reheated and then slowly cooled to obtain a desired orientation. The touch panel film is directly adhered to the liquid crystal display panel to obtain a pen-based input system. The book nest test performed on the pen-based loser system shown in 圏 59 shows that a sufficiently bright display with high contrast can be observed from a direction that is normal to the panel's normal side toward the lower side of the display panel. Moreover, only a dark display can be observed in directions other than the user's perspective, which can easily prevent data from being exposed inappropriately. In addition, because the polymer step between the substrates (Figure 58C) is satisfactory (____- 40 · ϋ 适财财财财料料 CN 秘秘 210 210 210 ΐ ΐ 适适适适适适适适适适适适适适(Please read the precautions on the back before filling this page) A7 B7 V.

Invention Description (39). Therefore, the surface coating film corresponds to the corrugated portion of this example. Moreover, a display electrode can be formed on the reflector. The obtained reflector including a smooth film and a surface coating film was adhered to a counter substrate having transparent electrodes. Then, a mixture of the liquid crystal material and the polymerizable monomer material is injected into the gap between the adhered substrates. It is preferable to use a photopolymerizable material as the polymerizable monomer material. The mixture becomes isotropic at a specific temperature (isotropic temperature) or higher, and separates into two phases at a temperature lower than the isotropic temperature. One phase is a phase including the main component monomer (that is, a monomer-rich phase), and the other phase is a phase including the main component liquid crystal (that is, a liquid crystal-rich phase). By polymerizing the monomers to achieve phase separation, a polymer wall is formed. In this example, a mixture in which the two-phase coexistence temperature range is about 10 r or higher is used. After that, the display panel is slowly cooled after the isotropic temperature (about 0.001 to 0.3 ° C / minute) 'to generate liquid crystal droplets. Due to the surface tension, the liquid crystal droplets agglomerate and become large in a portion corresponding to the flat portion on the lower side of the reflector. When the liquid crystal droplets fill the portion, UV light irradiation is performed. As a result, the monomer-rich phase located in the corrugated portion of the reflector is cured to form a polymer wall. Thus, the reflection type liquid crystal display device of Example 21 was completed. As mentioned above, the polymer wall can be easily formed by modifying the shape of the reflector in the thickness direction, as shown in FIG. 60. In this example, the shape of the reflector is modified by forming reflective parts on other films (that is, the surface coating film), as shown in Figure 61A. 6 Alternatively, the shape of the reflector can modify the shape of the substrate in the thickness direction (Figure 61B) , By modifying the shape of the metal film in the thickness direction (Figure 61C), or by selectively sandwiching other materials between the substrate and the metal film -42- This paper uses the Chinese National Standard (CNS) A4 size (210X297) Ii) II — — ——————— • Xiang--Sul T (Please read the notes on the back before filling out this page} Stamped by the Consumers ’Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs A7 B7 V.

Because of this setting, the reflective liquid crystal display device of Example 26 can display a high-contrast image.

This reflective liquid crystal display device is an improved type described in the twenty-third embodiment. In 囷 74, the same components of the reflective liquid crystal display device are denoted by the same reference numerals, and a description thereof is omitted.

The material strip 101 serves as a display electrode and is arranged to cross the counter positive electrode 80. The transparent electrode is formed on the counter substrate 73 at a right angle with a transparent material such as ITO when the reflector 78 is connected to the counter electrode 73. A portion where the display electrode 101 and the counter electrode 80 overlap each other serves as a pixel portion. -48-This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm) A7 B7 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the Invention (46) According to Example 27, it is not necessary to use a photomask The polymer wall 91 is formed because the counter electrode 80 and the display electrode 101 also serve as a mask for UV light irradiation. Therefore, the reflection type liquid crystal display device is simpler than those who need to use an optical mode. In order to perform multi-color display, a color filter including a plurality of color portions is provided on the counter substrate 73. In 滤 75, a color filter composed of a red portion R, an edge color portion g, and a blue portion B will be described. The colored portions of the color filter have a stripe shape 'arranged to correspond to the counter electrode 80. Therefore, each color filter bar intersects the display TF electrode on the reflector 78. It is a known technique to obtain a multi-color display device using a color suppressor. However, the display must be dimmed by the presence of color filters. Therefore, it is necessary to improve the brightness of the color display device. In this regard, the use of the reflector of the present invention is extremely advantageous. In other words, improving the brightness of a color LCD panel is far more advantageous than improving other types of LCD panels. If a color filter is provided, as shown in FIG. 75, it is formed by irradiating a mixture of a liquid crystal material 83 and a polymerizable precursor with UV light incident on the substrate 73, and the counter electrode 80 and the display electrode 101 are used as masks. Therefore, the color filter needs to transmit at least a part of the UV light. To form a polymer wall 91, the color filter needs to transmit at least 30¼ UV light. Alternatively, the UV light intensity is not sufficient to fully polymerize the polymerizable precursor. Therefore, if a color filter is provided in the reflective liquid crystal display device of Example 27, the UV light transmittance of the color filter is 30% or more. Multiple switching elements can be provided to individually drive each pixel. In this case, the display electrodes connected to the switching elements are formed of, for example, a matrix using a metal film, so that a portion surrounding the display electrodes transmits light. Furthermore, the display electrodes are located on the switching element and on the line combined with the insulating layer sandwiched therebetween. ____ -49- This paper size applies Chinese National Standard (CNS) conformance (21〇χ297 mm) ---- I m I.

Description of the invention (47) In any case, an additional smooth film can be formed on the reflector. If a smooth film is formed on the reflector, the negative influence of the micro concave / convex portion on the surface of the reflector on the characteristics of the reflective liquid crystal display device can be reduced. As mentioned earlier, when the surface in contact with the liquid crystal material has a concave / convex portion, certain problems occur, for example, the orientation of the liquid crystal molecules is disordered. To avoid such problems, a smooth film is provided if necessary. In addition, in any of the foregoing embodiments, the surface deformed portion such as a concave / convex portion has at least one cross-section taken along a plane parallel to the substrate, and its shape is different from a circular shape and any kind of equilateral polygon having four or more sides. In this case, the shape of the surface deformed part projected on the surface perpendicular to the observation direction of the surface deformed part depends on the observation direction. The light incident on the concave / convex portion is reflected in a specific direction depending on the shape of the concave / convex surface. Therefore, the intensity of the reflected light depends on the observation direction. As a result, the reflector provides a particularly bright display in special directions. As for the shape of the concave / convex portion, those shown in Figs. 72A to 72C are not suitable. 72A to 72C each show a graphic, an octagon, and a hexagon. Moreover, in any example, the surface deformed portion formed in the reflector has at least one symmetrical cross section. For symmetrical pumping, the ones shown in 囷 73A and 73B apply. The concave / convex portion shown by 囷 73C does not have symmetrical drawing. This shape is not applicable. As mentioned above, according to the present invention, the reflector includes at least one substrate and a metal film. A plurality of surface deformed portions are formed between the substrate and the metal thin film, and have asymmetrical cross sections. The surface deformed portion is a concave / convex portion. Due to this structure, light can be reflected from the metal thin film in a specific direction. -50

Description of the Invention (48) Each section of the surface deformed part has an inclined shape with the substrate. The shape has an asymmetrical tilt distribution with respect to the axis on the substrate; the average tilt distribution of all surface deformations is asymmetric when viewed from the axis on the substrate surface. In this case, a reflector may be provided which reflects light incident on any position of the substrate in a specific direction under high reflected light intensity. A reflector is used in the display device to make the specific direction coincide with the direction in which the observer views the display, and the reflected light is directed toward the observer. Therefore, a bright and comfortable display can be obtained. In addition, the scraped surface of the surface deformed portion has a curved portion, and the metal thin film located on the curved portion reflects light in a specific direction. In this case, the intensity of the reflected light becomes uniform in a region where the reflected light having a high reflected light intensity is obtained. Therefore, a substantially uniform bright display can be observed in a specific direction. Furthermore, the convex / concave portion that reflects light in a specific direction is not a straight line. Therefore, reflection of reflected light can be prevented. Therefore, reflected light having a more uniform light intensity can be obtained. Further, the surface deformed portion includes other cross sections taken along a plane parallel to the substrate, the other cross sections having a shape different from a circle and any isolateral polygon having four or more sides. In this case, the shape of the concave / convex portion projected on the surface perpendicular to the observation direction of the concave / convex portion depends on the observation direction. The light incident on the concave / convex portion is reflected in a specific direction depending on the shape of the concave / convex surface. Therefore, the intensity of the reflected light depends on the observation direction. As a result, the reflector provides a particularly bright display in a particular direction. The other sections of the surface deformed part are symmetrical, and the surface deformed parts are arranged so that the other sections of the surface deformed part are symmetrical to the vertical direction of the substrate.

In this case, the reflected light intensity distribution becomes symmetrical with respect to the vertical axis of the substrate. This reflector provides superior visibility to the observer. In the reflector of the present invention, the deformed surface portions are arbitrarily arranged on the substrate, and are arranged in the same direction. Therefore, the intensity distribution of the reflected light from one concave / convex portion is consistent with the reflected light from the other concave / convex portion. Therefore, the intensity distribution of the reflected light provided by the overall substrate is the same as that provided by a concave / convex portion. As a result, light can be reflected in a specific direction to obtain a reflector providing a high-brightness display. Furthermore, the reflection type liquid crystal display device having the reflector of the present invention shifts the diffused direction of incident light. Therefore, the reflected light is not directed toward a direction irrelevant to the observation angle of the user ', but is mainly directed toward the observation angle of the user. Therefore, a reflective liquid crystal display device having a high-brightness display is obtained.

Can be used as a mask instead of a transparent electrode. In this case, the pixels to be surrounded by the polymer wall can be more clearly defined to provide more enhanced and more desirable than expected for phase separation. Alternatively, according to the present invention, the polymer wall may be gradually cooled by slowly cooling the mixture containing the liquid crystal material and the polymerizable precursor so that the mixture is phase separated before the light irradiation process. In this case, the manufacturing process is simplified. The reflective liquid crystal display device of the present invention may further include a phase plate and a polarizer. The liquid crystal material includes liquid crystal molecules aligned in a uniaxial direction, and has a characteristic of displaying a high contrast image in a predetermined viewing angle direction. The predetermined viewing angle corresponds to a specific direction of light reflected by the reflector. In this case, the display brightness can be improved due to the single-layer polarizer system. Furthermore, in a reflective liquid crystal display device, an image display cannot be observed in a region where the lowest quality display is observed. Therefore, it is possible to eliminate the contrast reversal caused by the single polarizer system which is caused by too high viewing angle dependence. As a result, diastolic use can be achieved. In addition, the retardation of the liquid crystal layer and the retardation of the phase plate are set to meet predetermined conditions when the display is bright and dark.
