These designs will eliminate the air between the transparent touch panel 14 and the front light unit 15 Floor. Since the refractive index of air (1.0) is different from that of glass or transparent resin (1.4 to 1.7), if the air layer exists between the lower electrode plate 11A or 11B and the light guide plate 3. Will reduce the light transmission. This design enables the light guide plate 3 and the transparent touch panel 14 to be connected together via the transparent resin layer 12, and removes the air layer interposed between the light guide plate 3 and the transparent touch panel 14, so the light guide plate 3 and the transparent touch can be improved.

Description of the invention (12) Easy to complete. In various embodiments, external light entering through the outside of the uppermost transparent touch panel 14 and passing through the light guide plate 3 and the reflective liquid crystal display panel 5 of the front light unit 15 will be reflected at the reflective plate 6 and again Projected outward through the reflective liquid crystal display panel 5, the light guide plate 3, and the transparent touch panel 14. Since the external light passes through the components of the display device twice, the light transmittance of the reflective liquid crystal display panel 5 is considerably lower than that of the transmissive liquid crystal display. Therefore, it is important to omit two layers, that is, the air layer and the support 13 to improve the light transmittance. In particular, the air layer has a large refractive index difference from the light guide plate 3 and the lower electrode plates 11A * 11B, etc., so that reflection at the interface between the air layer and other layers will reduce a large amount of light. For example, 'When a transparent acrylic plate is used as a transparent light guide plate, due to the refractive index difference between the acrylic plate and the air layer, about 7% of the transmitted light loss β is reflected from the surface. The reduction of the air layer has a good effect on the improvement of light transmittance. In the above example, the 7% loss can be reduced. The aforementioned front light unit 15 will be described below. The design that the light guide plate 3 is superposed on the reflective liquid crystal display panel 5 requires that the light guide plate 3 has sufficient light transmission efficiency without hindering the visibility of the liquid crystal display panel. A thin rectangular plate can be used as the light guide plate 3.

Description of the invention (13) Ester resin, polyethylene resin, or polyester resin. In the above first embodiment, since the transparent touch panel 14 is provided on the topmost side, if there is a distance between the top surface and the bottom surface of the light guide plate 3, a parallax will be generated; that is, it is located in the reflective type. If the distance between one surface of the light guide plate on the side of the liquid crystal display panel 5 and the input surface of the light guide plate on the side of the transparent touch panel 14 is too large, a displacement will occur between a display position and an eight position. When the thickness of the light guide plate 3 is set to be as small as 0.3 to 2.0 mm, 'the surface of the light guide plate 3 on the side of the reflective liquid crystal display panel 5 and the wheel of the light guide plate 3 on the side of the transparent touch panel 14 The distance between the entrance surfaces is kept no more than 3.0mm, and the thickness is preferably 0.3 ~ i, 5mm. When the thickness of the light guide plate 3 is less than 0.3 mm, the light guide plate 3 will be difficult to process and 'a sufficient amount of light will not be obtained from one end face of the light guide plate 3 where the light source 4 is located. "When the thickness exceeds 2.0 For mm, the front light unit 15 will increase thickness and weight and lose portability. The light guide plate 3 can be made into a wedge shape or the like, except for a flat plate having a uniform thickness. If both the upper and lower surfaces of the light guide plate 3 are made mirror surfaces, the incident light will be sent to an end surface, which is opposite to the incident end surface of the light guide plate 3, and the incident light will be repeatedly reflected on both the upper and lower surfaces. , Almost no light is projected to the front, that is, only at the incident end face and the opposite end face. In order to solve this problem, the light diffusion layer 8 is disposed on at least one side of the light guide plate 3 on the side of the reflective liquid crystal display panel, or on the surface of the display panel, so the light in the light guide plate 3 will be directed toward the light guide plate 3. The reflective liquid crystal display panel 5 appears.

Description of the invention (M) Crystal display board 5 At the time, the reflective liquid crystal display panel 5 can be sufficiently illuminated. The light emitted from the light source 4 advances toward the other end face opposite to the incident end face of the light guide plate 3, and undergoes repeated total reflection in the light guide plate 3 to illuminate the entire reflective liquid crystal display panel 5. The light diffusing layer 8 of the light guide plate 3 needs to have sufficient light transmission efficiency and can be used together with external light, and must not hinder the visibility of the liquid crystal display panel. Therefore, the astigmatism layer 8 is suitable for adopting a fine shape, in particular, a layered pattern, a grain shape, a prism shape, and the like. The fine dot layer made by screen printing is usually used for the background light of the astigmatism layer 8. The fine dot layer in this example has a dot diameter of not less than 300 μm (micrometers), and a pigment is mixed in to Enhance light scattering. If the astigmatism layer 8 manufactured in this way is directly used as the front light unit 15, the liquid crystal display portion 7 will be occupied by a high ratio of fine dots, and when used with external light, and when the front light unit 15 is used When turned on, it will make the visibility worse. In the fifth embodiment of the present invention, the light diffusion layer 8 of the front light unit of the touch panel device incorporating the front light is specifically designed as described below. For example, a fine dot layer pattern made of a varnish with a transparent or translucent resin having a higher refractive index as that of the light guide plate 3 is provided on the light guide plate 3 on the side of the reflective liquid crystal display panel 5 On the surface, a light diffusion layer 8A is formed. The other surface of the light guide plate 3 on one side of the display surface is made into a mirror surface (see FIG. 8).

'Therefore, the visibility of the reflective liquid crystal display panel 5 will increase ° into the light guide plate 3 The light will be totally reflected repeatedly inside, and will be sent to the opposite end face of the incident end face of the light guide plate 3. The light rays will again pass from the light diffusing layer 8A provided on the light guide plate 3 on the side of the reflective liquid crystal display panel 5 The fine dots are emitted to illuminate the reflective liquid crystal display panel 5. The amount of light emitted from the astigmatic layer 8A can be adjusted by adjusting the step ratio of the astigmatic layer 8A. Therefore, the reflective liquid crystal display panel 5 can be Uniform illumination. According to the sixth embodiment of the present invention, One of the front light units of the touch panel device, the fine dot hierarchical pattern can be provided on the surface of the light guide plate 3 on the display surface side, and has the same fine dot circle diameter and area ratio as the foregoing, and it also uses the ratio The light guide plate 3 has a higher refractive index transparent or translucent resin as the main component of the paint and contains a light-dispersing pigment to form a light-diffusing layer 8B (see FIG. 9).

Astigmatism layer 8D 'is a fine granular material that does not greatly reduce display visibility (see Fig. 10). The granular light diffusing layer 8D 'of the light guide plate 3 is obtained by forming a granular shape on the inner surface of the mold and forming the granular shape when the light guide plate 3 is formed. Alternatively, the surface of the light guide plate 3 may be subjected to a fine roughening treatment with a diameter of about 30 / zm to form the light diffusion layer 8D. The light entering from the end surface of the light guide plate 3 will be scattered inside the light diffusing layer 3 due to the granular or rough shape of the light diffusing layer 8D, and a part of the light will be projected onto the reflective liquid crystal display panel 5. Many prisms can be provided as a light-scattering layer 8E on the surface of the light guide plate 3 on the side of the reflective liquid crystal display panel 5 which is parallel to the incident end face of the light guide plate 3 '. The front light unit of the eighth embodiment of the invention is a front light touch panel device (see FIG. 11). The light incident on the light guide plate 3 will illuminate the reflective liquid crystal display panel 5 through the prism surface of the light diffusion layer 8E. The prism system of the astigmatism layer 8E is, for example, a regular triangle, a lens shape, or the like. The size or pitch of the prisms of the astigmatic layer 8E is proportionally changed according to the distance from the incident end face, and the balanced output of the astigmatic layer 8E is controlled. The prisms and the like of the astigmatism layer 8E are preferably formed at a pitch of 30 to 500 μm and a width of 30 to 100 / zm, so as not to adversely affect its visibility.

Description of the invention (17) According to the embodiments of the present invention, the astigmatism layer 8 It can be made of a transparent or translucent resin with a higher refractive index than the light guide plate 3. In fact, according to the ninth embodiment of the present invention, a front light unit of a touch panel device incorporating a front light can be provided with a layer of transparent resin having a refractive index greater than that of the light guide plate 3 on the light guide plate 3 on the display surface side. Light scattering layer (see Figure 12) "light entering the light guide plate 3 will be reflected to the light scattering layer 8C at one of the interfaces of the light guide plate 3, which is again projected into the air layer due to the difference in refractive index between them To illuminate the reflective liquid crystal display panel 5 uniformly. In this configuration, since fine dots and the like are not shown on the front surface 'of the light guide plate 3, the visibility of the reflective liquid crystal display panel 5 is hardly affected. The light source 4 is provided at one end surface of the light guide plate 3. The light source 4 is disposed on at least one side of the rectangular light guide plate 3. A cathode fluorescent tube, an LED (light emitting diode) or the like can be used as a light source. The cathode ray tube is a straight tube, and the L-shaped tube can span the two adjacent sides. A U The tube can be extended to three adjacent sides. As shown in Figs. 4 to 7, a reflector 49 can be set, so that the light projected from the light source 4 can be effectively condensed to the incident end face of the light guide plate 3. The reflector 49 is preferably made of a metal plate having a surface capable of reflecting light like a mirror.

Most of the light entering the transparent touch panel 14 is totally reflected on the front surface of the lower electrode sheet 丨 丨, that is, ' At the interface between the lower electrode and the air layer, the light rays are sent to the opposite end face of the incident end face of the light guide plate 3, and the total reflection at the interface and the total reflection at the back of the light guide plate 3 are repeated. A part of the light entering the transparent touch panel 14 is not completely reflected at the interface, and the interface is between the electrode under the insulating substrate provided on the lower electrode sheet 11 and the air layer, because the lower electrode sheet 11 The top surface of the insulating substrate is provided with small convex bodies and oblique depressions 58 '. Therefore, the interface between the lower electrode and the air layer corresponds to the shape of the small convex bodies and oblique depressions.
