Description of the invention (1) (Background of the invention) The present invention relates to a flat display device, and in particular, to a method of condensing means, such as a micro lens, corresponding to each pixel of a display screen. Flat display device with light-concentrating substrate. In recent years, although a high-density and large-capacity flat panel display device capable of obtaining high display quality has been improved. Flat display devices: Because there is no crosstalk between adjacent pixel electrodes, a high contrast display can be obtained. At the same time, a transmissive display can be implemented and it is easy to become large. Therefore, thin film transistors are mostly used as elements for driving pixels. (Hereinafter abbreviated as TFT) an active matrix liquid crystal display device. The driving elements of these liquid crystal display devices include aS i TFT made of amorphous silicon (hereinafter abbreviated as a-S i), and p-S i made of polysilicon (hereinafter abbreviated as P-S i). TFT becomes a product. Among them, p — S i TFT is a kind of electron with higher mobility than a_S i TFT, and it can reduce the size of the active element and increase the number of pixels on the pixel electrode. The circuit for driving the scanning lines and the signal lines can be integrally formed on the active matrix substrate. Therefore, there is no need to externally install the IC for driving, etc. on the LCD screen, the installation process can be omitted, and the cost can be reduced. These P-S i TFTs are used to produce high-definition active-matrix liquid crystal display devices. By using a projection lens to enlarge and project, a large-screen display can be easily realized. Therefore, a front-type data projector projected from the front side of the screen, or a rear-type projected from the back side of the screen has been developed.

Description of the Invention (2) Television. In these projection type liquid crystal display devices, in order to reduce the size, weight, and cost of the projection mechanism, 'the miniaturization of the liquid crystal panel is expected. On the other hand, in order to make the screen brighter, the liquid crystal is improved. The size of the display device and the use of high-brightness and high-power light sources at the same time to improve the efficiency of the optical system. The size of the LCD screen "" when the smaller the size of the high-definition, the smaller the size of the data size, the implementation of the use The micro lens substrate collects incident light at the pixel openings to effectively increase the number of pixels. However, the above-mentioned liquid crystal display device has the following problems. As the micro lens substrate, the ion lens is used. However, the microlens system according to the ion exchange method must use a soda glass substrate. The coefficient of thermal expansion of the soda glass substrate system is more than twice that of the glass commonly used in LCD screens. Therefore, with the high definition of LCD screens, When light is irradiated at a high illuminance, the positional relationship between the pixel openings of the liquid crystal panel and the microlenses of the microlens substrate due to thermal expansion causes a problem of deviation. Therefore, as a microlens substrate, a glass substrate was developed to Various convex lenses. Fig. 9 shows a configuration of a flat display device related to the present invention using the plasma-exchange method microlens substrate 61. An array substrate 1 formed by TFTs 2 is arranged as an exchange element pair. 1 and the opposite substrate 15, and a liquid crystal composition 14 is installed in the middle through a sealing member to form a clamped state to form a liquid crystal panel 10. _ On the surface of the LCD screen 10, a micro Lens substrate 51. The microlens substrate 51 is formed in one surface of the glass substrate with a microlens 5 composed of a high refractive index area. Since the surface of the microlens substrate 51 is flat, The paper size adhered to the LCD screen 1 〇 applies the Chinese national standard (CNS > A4 specification (2) 0 X 297 mm) (Please read the precautions on the back before filling this page) ^ III Order ----- ----- · I.

Description of the invention (3) When facing the substrate 15, use Ultraviolet-curing adhesive 5 3. For ion-exchange microlenses, the ultraviolet-curing adhesive 5 3 can be used with the same refractive index as glass, and the degree of freedom in selecting the adhesive is greater. However, the ion-exchange method As described above, the microlens system has problems such as a large thermal expansion coefficient, and it cannot cope with future high definition. In addition, since these microlenses are adhered to the liquid crystal panel as a whole, they cannot be peeled off. Therefore, if the microlens substrate 51 is damaged after bonding, the so-called reworking process in which the microlens substrate 51 is peeled off from the liquid crystal panel 10 and regenerated into the expensive liquid crystal panel 10 cannot be performed. As described above, as microlenses that can correspond to the high definition of liquid crystal panels, there are methods of using a resin on a glass substrate to form a convex lens, or performing dry etching on a glass substrate to form a convex lens. The constitution of this case is shown in FIG. 10. By forming a convex lens 3 2 on the surface of a glass substrate, a micro lens substrate 31 can be fabricated. The microlens substrate 31 is arranged such that the convex lens 32 faces the surface of the liquid crystal panel 10, and is adhered with a low refractive index adhesive 34 interposed therebetween. Alternatively, it is also considered that the air-layer is interposed between the liquid crystal panel and the microlens substrate through an adhesive agent. However, as in the former case, when a low-refractive-index adhesive is used to adhere the opposing substrate and the microlens substrate on the entire surface, the low-refractive-index adhesive is relatively expensive and easily peels off. Also, as in the latter case, when bonding is performed through the air layer, the reflection of the # plane between the two parts will occur through the existence of the air layer, and the problem of light loss will occur each time, and it is easy for water to mix between the substrates. Creates ambiguity. This paper size applies to Chinese National Standard (CNS) A4 specification (2) ϋχ 297 mm) (Please read the precautions on the back before filling this page)

Description of the Invention (8) (Please read the precautions on the back before filling in this Page) Microlens substrate 31 having a microlens substrate 31 as a light condensing substrate. Microlens substrate 31 is provided on its surface with microlens 32 as a light condensing means formed by each pixel corresponding to a liquid crystal panel 10. The microlenses 32 and 2 can be formed on a glass substrate by molding using an ultraviolet-curable resin such as an epoxy-based or acrylic-based resin, and can be formed at a low cost. The liquid crystal panel 10 and the microlens substrate 31 are mounted as follows. The ultraviolet curing type sealing member 38 is coated on the counter substrate 21 or the microlens substrate 31, and both are posted to form an image display area 30 of the liquid crystal panel 10. After the alignment of the microlens substrate 31 and the liquid crystal panel 10 is performed, ultraviolet rays are irradiated to harden the sealing member 13 and adhere and fix it. When the microlens substrate 31 and the liquid crystal panel 10 are fixed, a liquid layer 34 having a lower refractive index than the microlens 32 is interposed therebetween. When the microlens 3 2 is formed of, for example, an epoxy resin having a refractive index of 1.59 or a propylene resin having a refractive index of 1.54, a liquid layer 3 4 having a lower refractive index must be used. For example, ethylene glycol or glycerin, or an aqueous solution of these may be used as the liquid layer 34. When a 50% aqueous solution of ethylene glycol or glycerol is used, the refractive index becomes about 1.38. Tetrafluoropolyether (refractive index 1 · 3), and root skin silicone oil (refractive index 1 · 3 8) may be used. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs to control the distance between the microlens 31 and the counter substrate 21 with high accuracy, a gap control member formed of, for example, glass fiber and having a thickness of 3 to 30 # m is mixed in In the sealing member 3 3. After the microlens substrate 3 1 is fixed on the counter substrate 11, the liquid layer 3 4 can be injected at a reduced pressure or pressure from the injection port 43 to obtain a desired interval. Then, the injection port 43 is closed via the sealant 44. However, if it can be processed and sealed uniformly, the size of this paper applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -11-Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 45 915 4 A7 B7 V. Description of the invention ( 9), the gap control member is not necessarily required. Of course, in the case of pressurized injection, not only an injection port, but also an injection port Π can be provided for injection and closed. However, when the microlens substrate 31 is installed in The process on the opposing substrate 21 and the surface of the microlens 32 arranged opposite to the opposing substrate 21 are easy to be injured. For example, during the cleaning process or the substrate transporting process, the k dust adhered from the end surface of the glass substrate. In the case where the surface of the microlens 32 is damaged. In order to protect these lens surfaces, for example, a gap between the microlens substrate 31 and the counter substrate 21 is ensured by the sealing member 3 3 including the gap control member as described above, and the consideration is made. The lens surface does not directly contact the counter substrate 2 1. Further, it is desirable to form a silicone-based coating or a fluorine-based resin coating on the lens surface. As the silicone-based coating, for example, Golgotec can be used. Made of N -1 0 3 X, etc. Because the silicone coating system has a charging prevention effect and abrasion resistance, dust is not easily attached, and the lens surface can be prevented from being damaged. Not only the lens surface, but also the micro lens The formation of a siloxane coating on the light incident surface of the opposite surface of the substrate 3 1 opposite to the opposite surface of the substrate 21 can reduce the interface reflectance of this surface. As a result, the effective light transmittance can be improved. As fluorine As the resin film, for example, "Septop" (trade name) manufactured by Asahi Glass Co., Ltd. or "Opstar" series resin film of JSR Co. may be used. These fluorine-based resin film systems not only have abrasion resistance And the refractive index is as small as about 1 3 8. Therefore, when the light incident surface ′ formed on the micro lens substrate 31 is used, the interface reflectance can be reduced. In addition, the paper standard of fluorine is applicable to China National Standard (CNS) A4.

Description of the invention (10) In order to improve the strength of the film when it is a resin film It is ideal to coat the resin after the coupling agent treatment and heat and dry it at 150 ° C for about 30 minutes. {Please read the precautions on the back before filling this page} According to the first embodiment above, due to the low refractive index liquid The layer 3 4 is interposed between the micro-lens substrate 31 and the liquid crystal panel 10, so that the light quantity loss caused by the reflection at the boundary surface between the micro-lens 32 and the opposite substrate 21 can be reduced. When an adhesive is applied between the microlens substrate and the counter substrate, and the entire surface is adhered, once the adhesion is performed, it will no longer work. In contrast, in the first embodiment, the counter substrate 21 and the microlens substrate 3 1 The liquid layer 34 is interposed instead of the entire surface, and is installed by the sealing member 33 at the peripheral portion. Therefore, the sealing member 33 is irradiated with ultraviolet rays or the like. Then, the opposing substrate 21 and the microlens substrate 31 can be peeled off. Therefore, for example, if the alignment accuracy of the two substrates is poor, or if failure occurs due to dust or the like, the expensive microlens substrate 31 or the liquid crystal panel 10 can be used for re-operation. As a result, cost reduction and yield improvement can be achieved. A flat display device according to a second embodiment of the present invention will be described with reference to Fig. 3. The LCD screen 10 printed by the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is the same as the above-mentioned first embodiment. The LCD screen 10 has an array substrate 11 formed of TFT12, and is bonded to the array by a sealing member 13. The counter substrate 2 1 in a state where the substrate 11 is arranged in an opposite direction, and the liquid crystal composition 14 in a state where the substrate 11 is sandwiched between the array substrate 11 and the counter substrate 21. On the surface of the opposing substrate 21 of the liquid crystal panel 10, a microlens substrate 61 as a light-condensing substrate is mounted. The microlens substrate 61 has microlenses 62 formed on the surface of the microlens substrate 61 corresponding to the pixels of the liquid crystal panel 10. Applicable to this paper standard Chinese National Standard < CNS) A4 (21 (JX 297 mm) -13- A7 45 915 4 ____B7_ 5. Description of the invention (11) One pixel has a micro lens, The three pixels of G, B, and B may have one microlens. The cross-sectional view shown in FIG. 1 corresponds to the case where one of the three pixels has one microlens. The microlens 6 2 is made of epoxy on a glass substrate, for example. UV curing resin based on acrylic or acrylic can be molded at low cost. The planar structure of micro lens substrate 61 is shown in Fig. 4 (a); The longitudinal section of the line B-B is shown in Fig. 4 (b). The microlens substrate 61 is formed: a microlens region 7 1 provided with a microlens 62, and a first peripheral region 72 formed on the outer periphery thereof. And the second peripheral area 73 formed on the outer periphery thereof. The second peripheral area 73 is a state in which an area having a height approximately equal to the apex of the microlens 62 in the microlens area 71 becomes a peripheral frame state. The first outer area 7 2 is an area having a height lower than the apex of the microlens 62 and the second peripheral area 73. A frame is formed between the micro lens area 71 and the second peripheral area 73. A part of the first peripheral area 71 is formed with an alignment for the alignment of the liquid crystal panel 10 and the micro lens substrate 61. Mark 7 4. The second outer peripheral area 73 is formed in all the outermost areas of the microlens substrate 61. However, it is formed only in the periphery of the adhesive fixing area. As shown in FIG. 1, a microlens substrate having such a structure is fixed. 6 1, so that the display area of the LCD screen 10 and the microlens 62 face each other. The fixing method is to apply, for example, an ultraviolet curing sealing material 65 to the microlens substrate 61 or the orientation of the LCD screen 10 Substrate 2 1, after the alignment of micro lens substrate 6 1 and LCD screen 10, it can be hardened by irradiating ultraviolet rays.

Description of the invention (12) The sealing material 6 5 is fixed by bonding. At this time, between the microlens substrate 61 and the counter substrate 21, a refractive index (in the case of an epoxy-based resin, 1.5 9 'when formed with an epoxy-based resin) is interposed between the microlens substrate 62 and an acrylic resin. 1.54) a liquid layer 64 with a relatively small refractive index, such as tetrafluoropolyether (for example, a brand name "Ferprin" manufactured by "Aqiwumante"): refractive index 1.3. In order to accurately control the distance between the microlens substrate 61 and the counter substrate 21, a gap material having a length of 3 to 30 made of glass fiber or the like may be mixed into the sealing material 65. Further, as shown in Fig. 5 showing a planar structure of the microlens substrate 61, an injection port 75 may be provided in at least a part of the second outer peripheral region 73. At this time, after the microlens substrate 61 is fixed to the liquid crystal panel 10, the liquid layer 64 is interposed therebetween under reduced pressure or pressure, and the interval can be accurately controlled. At this time, in order to easily perform the liquid injection, the second outer peripheral area 73 is not formed in the entire outer peripheral area of the microlens substrate 61.

Description of the invention (13) Distance. The liquid layer 64 is interposed between the microlens substrate 61 and the liquid crystal panel 10. However, in the past, in the peripheral area, bubbles tend to occur on the liquid crystal panel 64, which adversely affects the display quality. With regard to this kind of problem, according to this embodiment, since the area outside the microlens area is different from the height of the first outer area 72 and the microlens, it is possible to suppress bubbles in the display area by trapping bubbles in the first outer area. Therefore, the display quality can also be improved. It is desirable to form the second peripheral region 7 3 and the microlens 62 from the same material in the same process. In this case, the number of processes can be reduced and the cost can be reduced. However, other processes may be used to form this. Hereinafter, a third embodiment of the present invention will be described. This embodiment is different from the second embodiment in that the method of fixing the microlens substrate 61 to the liquid crystal panel 10 is different. As shown in Fig. 6, an ultraviolet curable resin 81 is applied to a part of the peripheral area of the display area on the counter substrate 21 of the liquid crystal panel 10. Alternatively, as shown in Fig. 7, the microlens substrate 61 is coated with an ultraviolet curable resin 8 2 in a part of the outer peripheral area that does not affect the display. After that, the low refractive index liquid layer is interposed between the liquid crystal panel 10 and the microlens substrate 61, and the positions are performed, and then they are attached to each other. Further, the ultraviolet-curable resin 8 1 or 8 2 is irradiated with ultraviolet rays to be cured and fixed. The liquid layer interposed between the microlens substrate 61 and the opposing substrate 2 1 of the liquid crystal panel 10 is the same as the first embodiment described above. The refraction of this paper applies the Chinese National Standard (CNS) A4 regulations. 210 (210 X 297 mm) —II --------— Agriculture ---- I ——Order-1! 1- * 5 ^ II (Please read the precautions on the back before filling in this page ) -16-45 91 5 4 A7 ______ B7 V. Explanation of the invention (14) The refractive index of the micro lens substrate 6 1 is higher than the refractive index (1.59 'in epoxy resin and about 1.5 in acrylic resin) 4) Tetrafluoropolyether may also be used. Any of the "ultraviolet-curable resins" can be used by ordinary users. However, in order to reuse the microlens substrate 6 1 after attaching the microlens substrate 61 to each other, a UV-curable resin that can be peeled off by warm water is used, such as a water-soluble temporary fixing agent made by Atal, or UV curing is used. Type of silicone. Silicone is adhesive and fixed. But because of weak adhesion, it can work again. In the first embodiment, the ultraviolet-curable resin is dropped on the opposing substrate 21 of the liquid crystal panel 10, or adhered and fixed at four locations on the microlens substrate 61. However, the pattern of coating the ultraviolet curable resin is not limited to dots. If it can be fixed to a pattern outside the display area, other patterns such as line patterns or planar patterns may be used. However, in the above-mentioned first, second, and third embodiments, the opposing substrates 2 1 of the liquid crystal panel 1 and the convex micro-lenses 62 of the micro-lens substrate 61 are opposed to each other and stuck to each other until they are adhered. Attention must be paid to where the lens is easily damaged. The causes of the scratches are, for example, processes such as a cleaning process or a substrate transport process, or chips or dust generated from the end surface of the glass substrate during the process including these processes. In order to protect the lens portion from such damage, a surface of at least the convex microlens 62 of the microlens substrate 61 may be protected by forming, for example, a silicone-based coating or a fluorine-based coating. As the siloxane-based coating, for example, N-1 0 3 X manufactured by Golgote, etc., the siloxane-based coating has the anti-charge effect and resistance (please read the back of the manual; i) (Fill in this page). -------- Line 1 Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper is printed in accordance with China National Standard (CNS) A / 1 Specification (210 " 297 Gongchu) -17- 4 5 91 5 4 A7 B7 5. Description of the invention (π) Abrasiveness, which makes it difficult for dust to adhere, and at the same time suppresses damage to the lens part. It is not only on the surface of the convex lens part, in the glass substrate, and the micro lens substrate. The same protective film 1 is formed on the light incident surface on the opposite side of the surface formed by 1 to reduce the interface reflectance of that surface. As a result, the actual light transmittance can be improved. Further, instead of the silicone-based coating, for example, a fluorine-based resin coating such as "Septop" (trade name) manufactured by Japan Asahi Glass Co., Ltd. or "Opstar" based JSR Corporation may be used. When forming a fluororesin coating, it is preferable to apply coating and heat drying (150 ° C, about 30 minutes) after the coupling agent treatment in order to increase the strength of the coating film. The embodiment described above is an example, and the present inventors are not limited. For example, after the microlens substrate 31 is mounted on the liquid crystal panel 10 in the first embodiment described above, a low refractive index liquid layer 34 is injected from the injection port 43. However, the injection port 4 3 is not provided, and after the liquid layer 34 is dripped inside the area surrounded by the sealing member 33 on the surface of the liquid crystal panel 10, the microlens base plate 31 may be attached. In the first embodiment described above, the microlenses 32 are formed of resin. However, microlenses made of convex glass may be used. The refractive index of glass microlenses is lower than 1.46 or 1.54. And the characteristics of the material have the advantage that it is not easy to deteriorate by moisture and the like. Although the present embodiment is described as a liquid crystal display device, it is not limited to a microlens, and can be applied to a flat display device in which a microlens substrate is mounted on a flat microlens in a whole surface. This paper size is applicable to the national standard of the country (CNS > A4 size (210 X 297 mm) (Please read the precautions on the back before filling this page)) --- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs-18- 4 5 915 4 a? ___B7 V. Description of the Invention (I6) In the above embodiment, the microlens substrates 3 1 and 6 1 are mounted and fixed on After the LCD screen 10, the low refractive index liquid layers 3, 4, 6 are sealed around the microlens substrate with a sealing agent. The use of a UV-curable resin as the material of the sealing agent can result in high productivity. For example, other materials such as water-curable resin may be used. In the above embodiment 1, the microlenses 62 made of resin are used. However, the microlenses made of glass are not limited to resin. Microlenses may also be used. Between the substrate 61 and the opposing substrate 21, it is preferable to interpose a layer having a lower refractive index than the microlens 62. However, in a glass microlens, the refractive index η of the glass is 1. 4 6 to 1.5 4 The ratio is lower than that of resin microlenses. Therefore, between the microlens substrate 6 1 and the counter substrate 2 1 A liquid layer having a low refractive index without an air layer is effective in optical characteristics. A concave type may be used as a microlens. In this case, a liquid layer having a higher refractive index than that of the microlens portion must be used. The refractive index of convex microlenses is ideally low-refractive index material for optical coupling. However, UV-curable adhesives are currently available as fluorine-based acrylic adhesives with a minimum of 1, 38. Refractive index and high cost. Tetrafluoropolyether has a lower refractive index of 1.30, which is a lens characteristic, and especially has the advantage of reducing spherical aberration. In addition, tetrafluoropolyether has thermal conductivity. The coefficient is also high, which can reduce the temperature unevenness in the LCD screen caused by light incidence. Therefore, the unevenness of the contrast can be suppressed on the screen display. The material is a chemically extremely inert liquid. This paper is suitable for this paper.

Description of the Invention (l7), because the solubility of water is also very low, it can improve the reliability of the device. As other liquids As the material, instead of the fluorine-based acrylic adhesive having a refractive index of 1.3, a root-skin silicone oil having the same refractive index may be used. Also, as shown in FIG. 8, a sealant for the outer periphery of the microlens substrate 61 is used. 6 3 may also be a bonding and fixing means for the frame 8 3 which also holds the holding member of the liquid crystal display device. The light-concentrating substrate is not limited to a microlens substrate, and a holographic color filter may be used. According to the flat display device of the present invention, since a liquid layer having a lower refractive index than that of the microlens is provided between the flat display screen and the microlens substrate, the light quantity loss caused by reflection at the interface between the two can be reduced. It can prevent the moisture or dust from being mixed when the liquid layer is interposed, and can improve the reliability of the device. When the micro lens substrate is adhered to the display screen by the entire surface with an adhesive, the freedom degree of selecting the most appropriate refractive index is low, but in the present invention, it is easier to focus light by controlling the refractive index of the liquid layer. Characteristics become most appropriate. In addition, according to the present invention, the portion adhered to the opposing substrate of the microlens substrate and the display screen is approximately the same height as the lens portion. Therefore, the uniformity of the distance between the microlens substrate and the counter substrate is excellent, which can reduce the deviation of the transmittance characteristics, and can prevent the display quality from being reduced due to uneven display.
