[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. Here, as shown in FIGS. 1 and 2, the substrate 1 has an overhanging portion 30 that overhangs the substrate 2.

  A polarizing plate 12 b is installed on the outer surface of the substrate 1. As will be described in detail later, a transparent conductive film 13 such as ITO (Indium-tin-oxide) is formed on the entire surface of the substrate 2, and a polarizing plate 12 a is formed on the surface of the transparent conductive film 13. is set up. The transparent conductive film 13 and a terminal of a ground line GND of an FPC (Flexible Printed Circuit) 22 are electrically connected to each other by a conductive member 27. Therefore, the transparent conductive film 13 functions as a conductive layer in the present invention.

  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 internal structure of 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. Here, it is assumed that the liquid crystal display panel 20 is, for example, an FFS (Fringe Field Switching) type liquid crystal display panel.

  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. 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 using 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.

  Returning to FIG. 1 and FIG. 2 and continuing the description, a driver IC 21 serving as a liquid crystal driving IC (driver) is directly disposed on the surface of the protruding portion 30 of the substrate 1 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 disposed. Further, on the surface of the overhanging portion 30 of the substrate 1, for example, wirings 23, 24, and 25 are formed by patterning a copper foil by a photoetching method or the like. 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. In FIG. 2, the driver IC 21 and the wirings 23, 24, and 25 are shown by broken lines in order to clarify the positional relationship with the insulator 26.

  In FIG. 2, the pixel electrode 8 is electrically connected to a part of the terminals of the driver IC 21 through the wiring 23 formed on the protruding portion 30 of the substrate 1. The common electrode 5 is electrically connected to a common potential terminal (COM terminal) of the driver IC 21 through a wiring 25 formed on the projecting portion 30 of the substrate 1. 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, if an electric charge is added to the surface of the polarizing plate 12 a installed on the outer surface of the substrate 2 due to static electricity from the outside, an electric field is generated between the substrate 1 and the substrate 2. The liquid crystal molecules of the liquid crystal 4 are affected by this electric field. 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 above, the transparent conductive film 13 such as ITO (Indium-tin-oxide) is formed on the entire surface on the outer surface of the substrate 2. A polarizing plate 12 a is provided on the surface of the transparent conductive film 13. The transparent conductive film 13 and the terminal of the ground line GND of the FPC 22 are electrically connected to each other by a conductive member 27.

  By doing so, the liquid crystal device 100 has a function of shielding and shielding external static electricity and the like, and can prevent an electric field from being generated between the substrate 1 and the substrate 2.

  In FIG. 2, for convenience of explanation, the conductive member 27 is illustrated as being shifted from the drive circuit such as the driver IC 21 and the wirings 23, 24, and 25, but actually, the conductive member 27 is formed in the vicinity of the drive circuit. Sometimes. In this case, the conductive member 27 may come into contact with the drive circuit disposed on the projecting portion 30 of the substrate 1 and short-circuit. In the following, the “drive circuit” is a concept including electronic elements such as driver ICs and wirings arranged on the surface of the overhanging portion 30 of the substrate 1, but is formed on the surface of the overhanging portion 30. The ground wiring GND is not included in the “driving circuit” described below. The ground wiring GND formed on the surface of the projecting portion 30 functions as the substrate ground wiring in the present invention.

  In the liquid crystal device 100 according to the present embodiment, the drive circuits such as the driver IC 21 and the wirings 23, 24, and 25 that are disposed on the protruding portion 30 of the substrate 1 are covered with the insulator 26. Specifically, as shown in FIG. 2, a portion other than the end portion where the terminal portion of the ground line GND of the FPC 22 in the projecting portion 30 of the substrate 1 is covered with an insulator 26. The conductive member 27 is formed by connecting the terminal portion of the ground line GND of the FPC 22 and the transparent conductive film 13. By doing so, the liquid crystal device 100 can prevent a short circuit between the drive circuit and the conductive member 27 disposed on the projecting portion 30 of the substrate 1.

  Here, the conductive member 27 does not overlap with the polarizing plate 12a, and the height of the conductive member 27 does not exceed the height of the upper surface of the polarizing plate 12a. Further, the polarizing plate 12a is smaller than the polarizing plate 12b in order to form the conductive member 27 as shown in FIG.

  Further, the conductive member 27 and the ground line GND of the FPC 22 in the projecting portion 30 of the substrate 1 are covered with a separate insulator (not shown) from at least the side surface of the substrate 1 to the lower substrate. By doing in this way, it can prevent that static electricity enters from the side surface of the liquid crystal display panel 20, and it can prevent that the electronic element on the board | substrate 1 is destroyed by static electricity.

  In FIG. 1, the entire drive circuit is covered with the insulator 26, but the present invention is not limited to this. Instead, as long as the purpose is to prevent a short circuit between the drive circuit disposed on the overhanging portion 30 of the substrate 1 and the conductive member 27, only the drive circuit in the vicinity of the conductive member 27 is insulated by the insulator 26. It may be covered.

(Manufacturing method of liquid crystal device)
Next, a method for manufacturing the liquid crystal device 100 according to the present embodiment will be described. FIG. 4 is a flowchart showing a method for manufacturing the liquid crystal device 100 according to the present embodiment. FIG. 5 and FIG. 6 are schematic views showing the manufacturing process of the liquid crystal device 100 according to the present embodiment, specifically, an enlarged plan view of the overhang portion 30.

  As shown in FIG. 5A, first, as a display panel manufacturing process, the substrate 1 and the substrate 2 on which the transparent conductive film 13 is formed in advance are bonded, and the two substrates 1 and 2 bonded together are bonded. After the liquid crystal is sealed in between, the wirings 23, 24, 25 and the ground wiring GND are formed on the projecting portion 30 of the substrate 1 by patterning. Then, the driver IC 21 and the FPC 22 are arranged on the substrate 1 by the COG (Chip On Glass) technique so as to be electrically connected to the wirings 23, 24, and 25 patterned on the overhanging portion 30 of the substrate 1 (steps). P11).

  Next, as a driving circuit covering step, the terminal portion 29 of the ground line GND of the FPC 22, that is, the end of the ground wiring GND on the side far from the flexible substrate 22 is masked. When applied to the overhanging portion 30 and then cured, the drive circuit such as the driver IC 21 and the wirings 23, 24, and 25 disposed on the overhanging portion 30 of the substrate 1 becomes an insulator as shown in FIG. 26 (process P12). Thereafter, as shown in FIG. 6A, as an optical sheet arranging step, the polarizing plate 12a is placed on the outer surface of the substrate 2 (step P13). At this time, the polarizing plate 12a is placed on the outer surface of the substrate 2 so that the transparent conductive film 13 is exposed on the projecting portion 30 side. On the contrary, after the polarizing plate 12 a is installed on the surface of the substrate 2, the driving circuit such as the driver IC 21 and the wirings 23, 24, and 25 may be covered with the insulator 26. However, in this case, when the liquid insulating material is applied to the overhanging portion 30 of the substrate 1, the polarizing plate 12a may be soiled. Therefore, when the driving circuit such as the driver IC 21 and the wirings 23, 24, and 25 disposed on the protruding portion 30 of the substrate 1 is covered with the insulator 26, the polarizing plate 12 a is installed on the surface of the substrate 2. Is better.

  Then, as shown in FIG. 6B, after the mask is removed as a mask removing step, a conductive paste 27a is applied as a conductive paste applying step, whereby the terminal portion 29 of the ground wiring GND of the FPC 22 is applied. The transparent conductive film 13 is electrically connected to each other (process P14). The conductive paste 27a is cured to function as the conductive member 27.

  Finally, as the insulator coating step, the conductive paste 27a and the ground line GND of the FPC 22 in the projecting portion 30 of the substrate 1 are covered with a separate insulator (not shown) (step P15).

  As described above, after driving circuits such as the driver IC 21 and the wirings 23, 24, and 25 arranged on the protruding portion 30 of the substrate 1 are covered with the insulator 26, the ground wiring GND and the polarizing plate 12 a are connected to the conductive member. By being electrically connected to each other at 27, it is possible to prevent a short circuit between the drive circuit and the conductive member 27 disposed on the projecting portion of the substrate 1.

[Modification]

  FIG. 7 is a plan view of the liquid crystal device 100 according to the first modification. In the liquid crystal device 100 according to the first modification, unlike the liquid crystal device 100 according to the present embodiment described above, the terminal of the ground wiring GND of the FPC 22 does not exist at the end of the overhanging portion 30 of the substrate 1. The terminal of the ground wiring GND of the FPC 22 exists in a partial region of the one overhang portion 30, and the terminal of the ground wiring GND and the transparent conductive film 13 are electrically connected to each other by a conductive member. Also according to this method, the liquid crystal device 100 has a function of shielding and shielding external static electricity and the like, and an electric field can be prevented from being generated between the substrate 1 and the substrate 2.

  In the above-described embodiment, the conductive member 27 is electrically connected to the terminal of the ground line GND of the FPC 22. However, the present invention is not limited to this. Instead, the conductive member 27 is electrically connected to the COM terminal of the driver IC 21. It may be connected to.

  FIG. 8 shows a schematic diagram of a liquid crystal device 100 according to a second modification. In the above-described embodiment, one predetermined position of the conductive layer and the ground line GND of the FPC 22 are electrically connected to each other by one conductive member 27. However, the present invention is not limited to this. Instead, As shown in FIG. 8, a plurality of positions on the surface of the conductive layer and the ground lines GND of the plurality of FPCs 22 may be electrically connected to each other by a plurality of conductive members 27. This makes it easier for the charge applied to the surface of the conductive layer to escape to the outside.

  In each of the above-described embodiments, the liquid crystal display panel 20 is an FFS liquid crystal display panel. However, the liquid crystal display panel 20 is not limited to this, and instead, an IPS (In-Plane Switching) liquid crystal display panel. It goes without saying that it 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 a liquid crystal display panel of another type such as a VA (Vertical Aligned) type instead. It is.
