  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following embodiments, the illumination device of the present invention is applied to a liquid crystal device.

[Configuration of liquid crystal device]
FIG. 1 is a cross-sectional view of a liquid crystal device 100 according to the present embodiment. FIG. 2 is a plan view of the liquid crystal device 100 according to the present embodiment. FIG. 1 is a cross-sectional view taken along the broken line AA ′ of the liquid crystal device 100 of FIG.

  The liquid crystal device 100 mainly includes a lighting device 10 and a liquid crystal display panel 20. The illumination device 10 is mainly composed of a light guide plate 11 and a light source unit 15. The liquid crystal display panel 20 is disposed to face the upper surface side of the light guide plate 11. The lighting device 10 includes a reflection sheet 14 on the lower surface side of the light guide plate 11.

  The light source unit 15 is disposed on the end face of the light guide plate 11 and includes a plurality of LEDs 16 that are point light sources. The light L emitted from each LED 16 enters the light guide plate 11 from the end face of the light guide plate 11. In the light guide plate 11, the light L changes its direction by repeating reflection between the upper and lower surfaces of the light guide plate 11 and is emitted toward the liquid crystal display panel 20.

  The liquid crystal display panel 20 has a display area substantially the same as the light emission area of the light guide plate 11. The liquid crystal display panel 20 is configured by bonding substrates 1 and 2 made of glass or the like through a sealing material 3 to form a cell structure and enclosing a liquid crystal 4 therein.

  As shown in FIGS. 1 and 2, a driver IC 21 serving as a liquid crystal driving IC (driver) is directly mounted on the liquid crystal display panel 20 by a COG (Chip On Glass) technique. At the end of the liquid crystal display panel 20, an FPC (Flexible Printed Circuit) 22 which is a flexible substrate is installed. Some terminals of the driver IC 21 are electrically connected to the FPC 22 through wiring 24 formed on the liquid crystal display panel 20.

  A polarizing plate 12 is installed on the outer surface of the substrate 1. The polarizing plate 12 is a general polarizing plate. A reflective polarizing layer 13 is formed on the outer surface of the substrate 2. The reflective polarizing layer 13 is integrated with the substrate 2 and is also called “wire-grid polarizers”. As shown in FIG. 2, the reflective polarizing layer 13 mainly has a structure in which the metal reflective film 13 a is formed in a stripe shape on the outer surface of the substrate 2. The metal reflection film 13a is formed of a metal material such as aluminum (Al) or silver (Ag). The reflective polarizing layer 13 will be described in detail later. The polarizing plate 12 and the reflective polarizing layer 13 have a transmission axis that allows light vibration to pass therethrough, and an absorption axis that does not allow light vibration to pass in a direction perpendicular to the transmission axis. The wire grid polarizing plate, which will be described in detail later, has an absorption axis in a direction parallel to the length direction of the slit, reflects light of a polarization component in a direction parallel to the length direction of the slit, and a direction perpendicular thereto. It transmits light of the polarized component.

  For example, a diffusion sheet or a prism sheet is provided as an optical sheet (not shown) between the illumination device 10 and the liquid crystal display panel 20. The diffusion sheet has a role of diffusing the light L emitted from the light guide plate 11 in all directions. The prism sheet has a role of condensing the light L on the liquid crystal display panel 20.

  Here, the liquid crystal display panel 20 will be described. The liquid crystal display panel 20 is a horizontal electric field type liquid crystal display panel. FIG. 3A shows an enlarged cross-sectional view of the liquid crystal display panel 20 in one subpixel. Referring to FIG. 1, FIG. 3A is an enlarged cross-sectional view of a portion surrounded by a wavy line 29. Here, the liquid crystal display panel 20 is assumed to be a FFS (Fringe Field Switching) liquid crystal display panel as an example.

  As described above, the liquid crystal display panel 20 is configured by sealing liquid crystal between the substrate 1 and the substrate 2. On the inner surface of the substrate 1, a common electrode 5 is formed on the entire surface by a transparent conductive member such as ITO (Indium-tin-oxide). On the inner surface of the common electrode 5, an insulating layer 7 is formed on the entire surface with acrylic resin or the like. A pixel electrode 8 is formed on the inner surface of the insulating layer 7 by a transparent conductive member such as ITO. On the other hand, a colored layer 6 is formed on the inner surface of the substrate 2. An alignment film 9 is formed on the inner surface of the colored layer 6.

  FIG. 3B shows a plan view of the pixel electrode 8. As shown in FIG. 3B, the pixel electrode 8 has a comb shape. Specifically, the pixel electrode 8 is composed of a conductive portion 8a, a conductive portion 8b, a conductive portion 8c, a conductive portion 8d, and a conductive portion 8e that are arranged in a straight line and have a linear shape. These conductive portions are integrally formed. The liquid crystal display panel 20 generates a horizontal electric field (lateral electric field) E between the conductive portions 8 a to 8 e of the pixel electrode 8 and the common electrode 5.

  In FIG. 2, the pixel electrode 8 is electrically connected to some terminals of the driver IC 21 through the wiring 23. The common electrode 5 is electrically connected to a terminal corresponding to COM of the driver IC 21 (hereinafter simply referred to as “COM terminal”) through the wiring 25. The driver IC 21 controls the magnitude of the electric field E based on a control signal supplied from an external electronic device via the FPC 22. In the horizontal electric field type liquid crystal display panel 20, by controlling the magnitude of the electric field E, the alignment state of the liquid crystal molecules in the liquid crystal 4 is changed, and the gradation on the display screen is changed.

  As can be seen from the above, in the horizontal electric field type liquid crystal display panel 20, electrodes such as the pixel electrode 8 and the common electrode 5 are formed only on the inner surface of the substrate 1, and electrodes are formed on the inner surface of the substrate 2. Not. Therefore, for example, when an electric charge is applied to the outer surface of the substrate 2 due to external static electricity or the like, an electric field is generated between the substrate 1 and the substrate 2, and the liquid crystal molecules of the liquid crystal 4 Will be affected. As a result, the liquid crystal display panel 20 cannot perform an appropriate display.

  Therefore, in the liquid crystal device 100 according to the present embodiment, as described in detail below, the metal reflective film 13a of the reflective polarizing layer 13 provided on the outer surface of the substrate 2 is electrically grounded, so that the outer surface of the substrate 2 can be electrically grounded. Let the charge added to be released.

(Configuration of reflective polarizing layer)
Next, the configuration of the reflective polarizing layer 13 will be described in detail with reference to FIGS. 4 is a cross-sectional view of the reflective polarizing layer 13 taken along the broken line BB ′ of the liquid crystal device 100 of FIG.

  As shown in FIG. 2, the reflective polarizing layer 13 includes a metal reflective film 13a provided at a fine pitch, a slit (gap) 13b, and a coupling portion 13c. As shown in FIG. 4, in the reflective polarizing layer 13, a plurality of metal reflective films 13 a are formed in stripes parallel to each other on the outer surface of the substrate 2 using a metal material such as aluminum (Al) or silver (Ag). . The gaps between the plurality of metal reflective films 13a formed in a stripe shape (linear shape) can transmit light and function as slits 13b. The dimension of each part is not particularly limited, but generally, the thickness d of the metal reflective film 13a is 100 to 400 [nm], and the width Ps of the slit 13b is 30 to 300 [nm]. The width Pm of one metal reflective film 13a is 30 to 300 [nm]. This metal reflective film 13a functions as the first metal reflective film in the present invention.

  Of the light L incident on the reflective polarizing layer 13, the light L1 in the polarization direction perpendicular to the length direction of the slit 13b is transmitted through the reflective polarization layer 13, but the light in the polarization direction parallel to the length direction of the slit 13b. L2 is not transmitted through the reflective polarizing layer 13 but is reflected. Therefore, in the reflective polarizing layer 13, the length direction of the slit 13b is an absorption axis, and the direction perpendicular to the length direction of the slit 13b is a transmission axis.

  Returning to FIG. 2 and continuing the description, in the reflective polarizing layer 13, a coupling portion 13 c is formed of a metal material such as aluminum (Al) or silver (Ag) at one end of the metal reflective film 13 a formed in a stripe shape. ing. The coupling portion 13c is also a metal reflection film, and is formed so as to overlap one end of all the plurality of metal reflection films 13a described above. Thereby, all the metal reflective films 13a are electrically connected to the coupling portion 13c. The coupling portion 13 c is electrically connected to the COM terminal of the driver IC 21 through the wiring 26. Thereby, the metal reflective film 13a is electrically connected to the COM terminal. The COM terminal is electrically connected to the ground line in the FPC 22 through the wiring 24. Therefore, the metal reflection film 13a is electrically grounded. This coupling | bond part 13c functions as a 2nd metal reflective film in this invention.

  As described above, in the liquid crystal device 100 according to this embodiment, even when a charge is added to the outer surface of the substrate 2, the charge is electrically grounded. It can come out of the substrate 2 through 13a. Therefore, in the liquid crystal device 100 according to the present embodiment, it is possible to prevent an electric field from being generated between the substrate 1 and the substrate 2. That is, in the liquid crystal device 100 according to the present embodiment, the metal reflection film 13a that is electrically grounded can be shielded from external static electricity. In particular, in the liquid crystal device 100 using the horizontal electric field type liquid crystal display panel 20, it is possible to prevent an appropriate display from being prevented due to external static electricity or the like by shielding the shield in this way. Moreover, since a general polarizing plate has a thickness of several tens [μm] even if it is thin, it is related to this embodiment as compared with the case where a general polarizing plate is installed on the outer surface of the substrate 2. In the liquid crystal device 100, the thickness of the device can be reduced. That is, in the liquid crystal device 100 according to the present embodiment, the shield can be shielded from external static electricity and the like, and the thickness of the device can be reduced.

(Manufacturing method of liquid crystal device)
Next, a method for manufacturing the liquid crystal device 100 according to the present embodiment will be described with reference to the flowcharts shown in FIGS. First, the first manufacturing method of the liquid crystal device 100 according to the present embodiment will be described with reference to the flowchart shown in FIG. FIG. 5 is a flowchart showing a first manufacturing method of the liquid crystal device 100 according to the present embodiment.

  First, as a display panel manufacturing process, two substrates 1 and 2 are bonded together, and after a liquid crystal is sealed between the two bonded substrates 1 and 2, the driver IC 21 is mounted by COG (Chip On Glass) technology. The liquid crystal display panel 20 is manufactured by being mounted on the substrate 1 (process P11).

  Next, as a metal reflective film forming step, after a metal material such as aluminum (Al) or silver (Ag) is formed on the outer surface of the substrate 2, the metal material is striped using a photolithography method. The metal reflective film 13a is formed by patterning (process P12).

  Then, as a bonding portion forming step, for example, a metal paste such as a silver paste is applied linearly so as to overlap one end of all the metal reflection films 13a formed in a stripe shape on the outer surface of the substrate 2. By doing in this way, the coupling | bond part 13c is formed so that it may overlap with the end of all the metal reflective films 13a (process P13). The reflective polarizing layer 13 is formed by the processes P12 and P13.

  And after the coupling | bond part 13c is connected with the COM terminal of driver IC21 by the wiring 26 (process P14), other attachment parts, such as the polarizing plate 12 and the illuminating device 10, are attached to the liquid crystal display panel 20, The liquid crystal display device 100 is completed (process P15).

  In the first manufacturing method described above, the metal reflection film 13a and the coupling portion 13c are formed separately. However, the present invention is not limited to this, and the metal reflection film 13a and the coupling portion 13c are integrally formed. It may be done. FIG. 6 is a flowchart showing a second manufacturing method of the liquid crystal device 100 according to this embodiment. FIG. 7 shows a plan view of the metal reflection film 13a and the coupling portion 13c when the metal reflection film 13a and the coupling portion 13c are integrally formed. In FIG. 7, the substrate 1, the driver IC 21, and the FPC 22 are omitted.

  First, as a display panel manufacturing process, two substrates 1 and 2 are bonded together, and after a liquid crystal is sealed between the two bonded substrates 1 and 2, the driver IC 21 is mounted by COG (Chip On Glass) technology. The liquid crystal display panel 20 is manufactured by being mounted on the substrate 1 (process P21).

  Next, as a reflective polarizing layer forming step, after a metal material such as aluminum (Al) or silver (Ag) is formed on the outer surface of the substrate 2, the metal material is comb-toothed using a photolithography method. By patterning the shape, as shown in FIG. 7, the metal reflective film 13a and the coupling portion 13c are integrally formed (step P22). That is, the metal reflection film 13a is formed in a stripe shape as the shape of the comb-shaped branch portion, and the coupling portion 13c is formed as the shape of the trunk portion of the comb-tooth shape.

  And after connecting part 13c is connected with COM terminal of driver IC21 with wiring 26 (process P23), other attachment parts, such as polarizing plate 12 and lighting device 10, are attached to liquid crystal display panel 20, The liquid crystal display device 100 is completed (process P24).

  In the above-described second manufacturing method, the metal reflective film 13a and the coupling portion 13c are integrally formed, so that the number of manufacturing steps can be reduced compared to the second manufacturing method. Therefore, when the liquid crystal device 100 is manufactured, the manufacturing process can be performed more efficiently by using the second manufacturing method than by using the first manufacturing method.

  In the first and second manufacturing methods described above, the reflective polarizing layer 13 is formed after the liquid crystal display panel 20 is manufactured. However, the present invention is not limited to this, and the reflective polarizing layer 13 is formed on the outer surface of the substrate 2. Needless to say, the liquid crystal display panel 20 may be manufactured by bonding the substrates 1 and 2 after forming the substrate.

[Modification]
Next, a modified example of the liquid crystal device 100 according to the present embodiment will be described. 8 to 11 are plan views of the liquid crystal device 100 according to the modification.

  In the liquid crystal device 100 according to the above-described embodiment, as shown in FIG. 2, the metal reflection film 13a is formed in a stripe shape parallel to the long side direction of the liquid crystal display panel 20, but the metal reflection film 13a. However, the shape is not limited to this. For example, as shown in FIG. 8, the metal reflective film 13 a may be formed in a stripe shape parallel to the short side direction of the liquid crystal display panel 20. Since the coupling portion 13 c needs to be formed so as to overlap one end of all the metal reflection films 13 a, the coupling portion 13 c is formed in parallel to the long side direction of the liquid crystal display panel 20. Furthermore, as shown in FIG. 9, the metal reflective film 13 a may be formed obliquely with respect to the short side or long side direction of the liquid crystal display panel 20. Even in this case, since the coupling portion 13c needs to be formed so as to overlap one end of all the metal reflection films 13a, the L-shape parallel to both the short side and the long side directions of the liquid crystal display panel 20 is used. Formed. That is, as shown in FIGS. 8 and 9, in the liquid crystal device 100 according to the modification, the metal reflection film 13 a can be formed in a stripe shape in any direction of the liquid crystal display panel 20. The transmission axis in the reflective polarizing layer 13 can be set in any direction.

  In the liquid crystal device 100 according to the above-described embodiment, as illustrated in FIG. 2, the coupling portion 13 c is electrically connected to the COM terminal of the driver IC 21 through the wiring 26, but is not limited thereto. Instead, as shown in FIG. 10, it goes without saying that it may be directly electrically connected to the ground wiring GND of the FPC 22 through the wiring 26a. As a result, the metal reflection film 13a is electrically connected to the ground wiring GND and is electrically grounded.

  FIG. 11 is a perspective view of the liquid crystal display panel 20 and the metal frame 30. FIG. 12 shows a plan view when the liquid crystal device 100 is covered with the metal frame 30. In FIG. 12, the metal frame 30 is indicated by a wavy line. As can be seen from FIG. 11, for example, the metal frame 30 is formed with claws 32 directed to the inside of the metal frame 30 at the edges of the four sides. As shown in FIG. 11, when the liquid crystal device 100 is mounted on the metal frame 30, the claws 32 come into contact with the coupling portion 13c or the metal reflective film 13a as shown by portions 33a and 33b surrounded by broken lines in FIG. It will be. That is, the nail | claw 32 will be electrically connected with the metal reflective film 13a. Even in this case, the metal reflection film 13a is electrically grounded, and the charge added to the substrate 2 passes from the substrate 2 to the metal frame 30 through the portions 33a and 33b in contact with the claws 32. Become. In this case, it is not necessary to perform wiring for grounding to the COM terminal of the driver IC 21 or the ground wiring GND of the FPC 22, and the manufacturing process of the liquid crystal device can be simplified. The shape of the claw 32 is not limited to the shape shown in FIG. 11 and FIG. 12, and it is needless to say that it may be any shape as long as it is in contact with the coupling portion 13 c or the metal reflective film 13 a.

  In the above-described embodiment, the reflective polarizing layer 13 is provided on the outer surface of the substrate 2, but is not limited thereto, and in addition, on the outer surface of the substrate 1, instead of the polarizing plate 12. In addition, a reflective polarizing layer 13 may be provided. In the above-described embodiment, the metal reflection film 13a is provided with the coupling portion 13c and is electrically connected to the COM terminal of the driver IC 21 via the coupling portion 13c. However, the present invention is not limited to this. Instead of this, it goes without saying that the connecting part 13c may not be provided, and may be electrically connected to the COM terminal of the driver IC 21 directly from one end of each of the metal reflection films 13a by wiring or the like. However, it is possible to electrically connect all the metal reflective films 13a to the COM terminals of the driver IC 21 by using only the wirings 26, and thus simplifying the wiring, by providing the coupling portion 13c rather than doing in this way. Can be a good idea.

  Furthermore, in the above-described embodiment, the liquid crystal display panel 20 is an FFS liquid crystal display panel, but is not limited to this, and instead is an IPS (In-Plane Switching) liquid crystal display panel. Needless to say, there may be. Furthermore, the liquid crystal display panel 20 is not limited to a horizontal electric field type liquid crystal display panel, but can be applied to another type of liquid crystal display panel such as a VA (Vertical Aligned) type instead. It is.
