Description

Technical Field

[0001] Embodiments of the present invention relate to a display device.

Background Art

[0002] In recent years, a display device that displays two different images (videos) on one screen has been put into practical use. When such a display device is applied to a car navigation device or the like, for example, it is possible to provide two different images to a plurality of users, such as displaying a map image for a vehicle driver and a television image for a passenger.

[0003] In such a display device, in order to display two different images on one screen, a parallax barrier pattern is provided between a transparent substrate made of glass or resin and a thick film transparent layer made of an organic layer. However, generally, since the organic layer has low resistance to moisture, if moisture enters the thick film transparent layer from the end of the thick film transparent layer, the parallax barrier pattern may peel off from the transparent substrate due to the entered moisture. According to this, display unevenness may occur, and there may be a disadvantage that two different images cannot be provided to a plurality of users.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments will be described with reference to the drawings. Note that the disclosure is merely an example, and the invention is not limited to the content described in the following embodiments. Modifications that can be easily conceived by those skilled in the art are naturally included in the scope of the disclosure. For the sake of clarity, in the drawings, the size, shape, etc. of each part may be changed with respect to the actual embodiment and represented schematically. In a plurality of drawings, the same reference numerals may be assigned to corresponding elements, and detailed descriptions may be omitted.

[0009] First, with reference to FIGS. 1 to 3, a configuration example of a liquid crystal display device 100 capable of realizing a two-screen display in which two different images (videos) are displayed on one screen will be described. In this embodiment, a case where the liquid crystal display device 100 is a liquid crystal display device of a method called the FFS (Fringe Field Switching) mode will be described. The liquid crystal display device 100 is an example of a “display device” capable of realizing a two-screen display.

[0010] In the liquid crystal display device 100, as shown in FIGS. 1 to 3, a first substrate SUB1 (array substrate) including a first transparent substrate 1 and a second substrate SUB2 (opposing substrate) including a second transparent substrate 2 are arranged to face each other. The liquid crystal display device 100 realizes a two-screen display in which an image (video) is separated by a parallax barrier pattern 40 described later and two different images (videos) are displayed.

[0011] On the surface of the first transparent substrate 1 on the Z1 direction side, a thin film transistor (TFT) 3 for pixel selection, a pixel electrode 4, and a common electrode 5 are formed.

[0012] In addition, as the detailed cross-sectional structure of one pixel, as shown in FIG. 3, a gate electrode 6 is provided on the surface of the first transparent substrate 1 on the Z1 direction side. Further, an insulating film 7 including a gate insulating film 7a made of a SiN film, a SiO2 film, or the like is formed on the gate electrode 6 and on the first substrate SUB1. A semiconductor layer 8 having a two-layer structure (not shown) including an a-Si layer in the lower layer and an n-type conductive n + a-Si layer is formed so as to overlap the gate electrode 6 in a plan view.

[0013] On the semiconductor layer 8, a source electrode 9 and a drain electrode 10 are formed so as to overlap the gate electrode 6 in a plan view. Further, in a plan view, the region of the semiconductor layer 8 sandwiched between the source electrode 9 and the drain electrode 10 functions as a channel region 8a. And the thin film transistor (TFT) 3 for pixel selection is composed of a gate electrode 6, a gate insulating film 7a, a semiconductor layer 8, a source electrode 9, and a drain electrode 10.

[0014] Also, an interlayer insulating film 11 made of a SiN film or the like is formed so as to cover the source electrode 9, the drain electrode 10, and the insulating film 7. A contact hole 11a is formed in a region corresponding to the drain electrode 10 in the interlayer insulating film 11. A planarization film 12 made of an organic film such as an acrylic resin is formed on the surface of the interlayer insulating film 11. Further, a contact hole 12a is formed in the planarization film 12. Furthermore, the pixel electrode 4 is formed of a transparent electrode such as ITO (Indium Tin Oxide) or IZO (Indium Zinc Oxide) so as to be connected to the drain electrode 10 through the contact hole 11a and the contact hole 12a on the surface of the planarization film 12.

[0015] Also, a passivation film 13 made of SiO2, SiN film, etc. formed at a low temperature is formed on the surfaces of the planarization film 12 and the pixel electrode 4. Further, the common electrode 5 is formed of a transparent electrode such as ITO or IZO on the surface of the passivation film 13. The common electrode 5 is provided with a plurality of openings 5a, and is configured such that an electric field is generated between the pixel electrode 4 and the common electrode 5 through the openings 5a. As described above, a fringe field switching (FFS) mode liquid crystal display device 100 is configured in which liquid crystal is driven by the lateral electric field between the pixel electrode 4 and the common electrode 5.

[0016] Also, an alignment film 14 made of an organic film such as polyimide is formed on the common electrode 5. The alignment film 14 is formed so as to cover the surface of the common electrode 5 and is formed so as to contact the passivation film 13 through the opening 5a of the common electrode 5. In this way, the first substrate SUB1 is constituted by the first transparent substrate 1, the thin film transistor 3, the interlayer insulating film 11, the planarization film 12, the pixel electrode 4, the passivation film 13, the common electrode 5, and the alignment film 14.

[0017] Also, as shown in FIGS. 2 and 3, a thick film transparent layer 20 made of an organic layer is formed on the surface on the Z2-direction side of the second transparent substrate 2. Also, as shown in FIGS. 2 and 3, a parallax barrier pattern 40 is formed on the surface on the Z2-direction side of the second transparent substrate 2. Color filters 21 of red (R), green (G), and blue (B) are formed on the surface on the Z2-direction side of the thick film transparent layer 20. Note that the liquid crystal display device 100 is provided with a plurality of pixels 22, and a color filter 21 is provided for each pixel 22.

[0018] Also, as shown in FIG. 3, a black matrix 23 formed of resin or the like is formed on the surface on the Z2-direction side of the thick-film transparent layer 20. The black matrix 23 is formed on the boundary of the pixel 22 in a plan view and is formed in a matrix shape. Further, an overcoat layer 24 as a protective film is formed on the surface on the Z2-direction side of the black matrix 23 and the color filter 21. Further, an alignment film 25 made of an organic film such as polyimide is formed on the surface on the Z2-direction side of the overcoat layer 24. In this way, the second substrate SUB2 is constituted by the second transparent substrate 2, the thick-film transparent layer 20, the parallax barrier pattern 40, the color filter 21, the black matrix 23, the overcoat layer 24, and the alignment film 25.

[0019] The first substrate SUB1 and the second substrate SUB2 are bonded together by a sealing material 30 (see FIG. 2), and a liquid crystal layer 31 is encapsulated between the alignment film 14 on the first substrate SUB1 side and the alignment film 25 on the second substrate SUB2 side. A backlight 50 is provided on the Z2-direction side of the first substrate SUB1, and light is configured to be emitted from the backlight 50 toward the second substrate SUB2 (Z1-direction side) from the first substrate SUB1.

[0020] The above-described parallax barrier pattern 40 is made of, for example, a resin layer or a metal layer such as chromium (Cr), aluminum (Al), silver (Ag), or nickel (Ni), and has light-shielding properties. Further, as shown in FIG. 1, the parallax barrier pattern 40 is provided with a plurality of substantially rectangular openings (slits) 40a formed to extend in the Y direction. The parallax barrier pattern 40 between the openings 40a is configured to block light. Further, the parallax barrier pattern 40 is configured such that two of the three colors (red (R), green (G), and blue (B)) of the color filter 21 are visible from the openings 40a of the parallax barrier pattern 40.

[0021] Incidentally, since the thick film transparent layer 20 is made of an organic layer, it has low resistance to moisture. If moisture enters the thick film transparent layer 20 from the edge of the thick film transparent layer 20, the parallax barrier pattern 40 may peel off from the second transparent substrate 2 due to the entered moisture. If the parallax barrier pattern 40 peels off from the second transparent substrate 2, there is a problem that the traveling direction of light from the backlight 50 cannot be appropriately distributed, so that dual screen display cannot be realized.

[0022] Therefore, the liquid crystal display device 100 according to the present embodiment suppresses the intrusion of moisture into the thick film transparent layer 20 by covering the edge of the thick film transparent layer 20 with a sealing material 60 described later. Hereinafter, with reference to FIGS. 4 and 5, a configuration example of the liquid crystal display device 100 according to the present embodiment will be described.

[0023] FIG. 4 is a schematic plan view showing a configuration example of the liquid crystal display device 100 according to the present embodiment. In FIG. 4, among the elements constituting the liquid crystal display device 100, only the first transparent substrate 1, the second transparent substrate 2, and the sealing material 60 are illustrated.

[0024] The first transparent substrate 1 has side surfaces 1a and 1b along the X direction and side surfaces 1c and 1d along the Y direction. The second transparent substrate 2 has side surfaces 2a and 2b along the X direction and side surfaces 2c and 2d along the Y direction.

[0025] In a plan view, the side surface 1a of the first transparent substrate 1 and the side surface 2a of the second transparent substrate 2 do not overlap. Similarly, in a plan view, the side surfaces 1b, 2b, the side surfaces 1c, 2c, and the side surfaces 1d, 2d do not overlap respectively. The first transparent substrate 1 has extension portions Ex1 (first extension portions) between the side surfaces 1a, 2a, between the side surfaces 1b, 2b, between the side surfaces 1c, 2c, and between the side surfaces 1d, 2d. In the example shown in FIG. 4, the width W2 of the extension portion Ex1 provided between the side surfaces 1a, 2a is larger than the width W1 of the extension portion Ex1 provided between the side surfaces 1b, 2b, between the side surfaces 1c, 2c, and between the side surfaces 1d, 2d. This is because the extension portion Ex1 between the side surfaces 1a, 2a functions as a mounting portion, a terminal portion (pad group) is formed on the extension portion Ex1, and a wiring substrate or an IC chip (not shown) constituting the liquid crystal display device 100 is mounted thereon.

[0026] On the extension portion Ex1 of the first transparent substrate 1, a sealing material 60 is provided so as to cover the end portions of the second transparent substrate 2 (more specifically, the end portions of the thick film transparent layer 20 to be described later) other than the end portions on the mounting portion side described above (that is, the side surfaces 2b to 2d other than the side surface 2a). In other words, the sealing material 60 is provided so as to cover the end portion of the second transparent substrate 2 (the end portion of the thick film transparent layer 20) on the extension portion Ex1 other than the extension portion Ex1 functioning as a mounting portion. The width W3 of the sealing material 60 is preferably set to, for example, 0.5 mm to 1.5 mm.

[0027] FIG. 5 is a schematic cross-sectional view of the liquid crystal display device 100 along the line C1-D1 in FIG. 4. As shown in FIG. 5, an interlayer insulating film 11, a planarization film 12, a passivation film 13, and an alignment film 14 are sequentially laminated on the Z1 direction side of the first transparent substrate 1 to constitute the first substrate SUB1. In FIG. 5, although the illustration of the elements constituting the thin film transistor 3 for pixel selection shown in FIG. 3, the pixel electrode 4, and the common electrode 5 is omitted, these elements are further arranged between the first transparent substrate 1 and the alignment film 14 as shown in FIG. 3.

[0028] As shown in FIG. 5, on the Z2-direction side of the second transparent substrate 2, a thick-film transparent layer 20, a color filter 21, an overcoat layer 24, and an alignment film 25 are laminated in this order to form the second substrate SUB2. A parallax barrier pattern 40 is formed between the second transparent substrate 2 and the thick-film transparent layer 20, and a black matrix 23 is formed between the thick-film transparent layer 20 and the color filter 21.

[0029] The first substrate SUB1 and the second substrate SUB2 are bonded together by a sealing material 30, and a liquid crystal layer 31 is encapsulated between the alignment film 14 on the first substrate SUB1 side and the alignment film 25 on the second substrate SUB2 side. Outside the sealing material 30, between the first substrate SUB1 and the second substrate SUB2, a spacer 32 for forming a cell gap is disposed.

[0030] As shown in FIG. 5, the first transparent substrate 1 has an extension portion Ex1 between the side surface 1b and the side surface 2b of the second transparent substrate 2. On the extension portion Ex1, a sealing material 60 is provided so as to cover the end portion (side surface 2b) of the second transparent substrate 2, the end portion of the thick-film transparent layer 20, the end portion of the color filter 21, and the end portion of the overcoat layer 23 (that is, the end portion of the second substrate SUB2). The sealing material 60 is formed, for example, of an acrylic resin, an epoxy resin, or a combination thereof. However, it is desirable that the sealing material 60 be formed of a material having higher moisture resistance than the thick-film transparent layer 20.

[0031] In this configuration, the sealing material 60 is provided, for example, in a process after the first substrate SUB1 and the second substrate SUB2 are bonded together by the sealing material 30, and in a process of forming a protective film (not shown) for protecting an IC chip or the like (not shown), so as to cover the end portion of the second substrate SUB2 including the end portion of the thick-film transparent layer 20.

[0032] Note that in FIG. 5, a cross-section of the liquid crystal display device 100 along the line C1-D1 in FIG. 4 is shown, but cross-sections of the liquid crystal display device 100 along the lines C2-D2 and C3-D3 in FIG. 4 also have a similar structure.

[0033] As described above, in the liquid crystal display device 100 according to the present embodiment, the end portion of the thick film transparent layer 20 is covered by the sealing material 60 provided on the extending portion Ex1. According to this, it is possible to suppress moisture from entering the thick film transparent layer 20 from the end portion of the thick film transparent layer 20, and to prevent the parallax barrier pattern 40 from peeling off from the second transparent substrate 2.

[0034] In the present embodiment, the case where the sealing material 60 is provided so as to cover the end portions of the thick film transparent layer 20 other than the end portion on the mounting portion side described above has been described. However, the present invention is not limited to this, and the sealing material 60 may be provided in a rectangular frame shape so as to cover the entire circumference of the end portion of the second transparent substrate 2 including the entire circumference of the end portion of the thick film transparent layer 20 (that is, the side surfaces 2a to 2d), as shown in FIG. 6, for example.

[0035] Hereinafter, modified examples will be described. (First Modified Example) The first modified example is different from the configuration shown in FIGS. 4 and 5 in that a cover member 28 described later is further provided on the second transparent substrate 2. Hereinafter, mainly, the parts different from the configuration shown in FIGS. 4 and 5 will be described, and the description of the parts similar to the configuration shown in FIGS. 4 and 5 will be omitted.

[0036] FIG. 7 is a schematic plan view showing a configuration example of the liquid crystal display device 100 according to the first modified example. In FIG. 7, among the elements constituting the liquid crystal display device 100, only the first transparent substrate 1, the second transparent substrate 2, the sealing material 60, and the cover member 28 are shown.

[0037] The cover member 28 has side surfaces 28a and 28b along the X direction and side surfaces 28c and 28d along the Y direction.

[0038] In a plan view, the side surface 28a of the cover member 28 overlaps with the side surface 1a of the first transparent substrate 1. Similarly, in a plan view, the side surfaces 28b, 28c, and 28d of the cover member 28 overlap with the side surfaces 1b, 1c, and 1d of the first transparent substrate 1, respectively.

[0039] Also, in plan view, the side surface 28a of the cover member 28 does not overlap with the side surface 2a of the second transparent substrate 2. Similarly, in plan view, the side surfaces 28b, 28c, and 28d of the cover member 28 do not overlap with the side surfaces 2b, 2c, and 2d of the second transparent substrate 2, respectively. The cover member 28 has extension portions Ex2 (second extension portions) between the side surfaces 28a and 2a, between the side surfaces 28b and 2b, between the side surfaces 28c and 2c, and between the side surfaces 28d and 2d.

[0040] A sealing material 60 is provided between the extension portion Ex1 of the first transparent substrate 1 and the extension portion Ex2 of the cover member 28 so as to cover the ends of the second transparent substrate 2 (more specifically, the ends of the thick film transparent layer 20, which will be described later) other than the ends on the mounting portion side.

[0041] In addition, in FIG. 7, the case where the side surfaces 28a to 28d of the cover member 28 and the side surfaces 1a to 1d of the first transparent substrate 1 overlap each other in plan view is shown, but the present invention is not limited thereto, and the side surfaces 28a to 28d of the cover member 28 and the side surfaces 1a to 1d of the first transparent substrate 1 may not overlap each other in plan view.

[0042] FIG. 8 is a schematic cross-sectional view of the liquid crystal display device 100 taken along the line E-F in FIG. 7. As shown in FIG. 8, a polarizing plate 26 is disposed on the surface of the second transparent substrate 2 on the Z1 direction side. Further, a cover member 28 is disposed on the Z1 direction side of the polarizing plate 26 via an adhesive layer 27. As the cover member 28, for example, a glass substrate, a resin substrate, or the like can be used.

[0043] As described above, a sealing material 60 is provided between the extension portion Ex1 of the first transparent substrate 1 and the extension portion Ex2 of the cover member 28 so as to cover the end of the polarizing plate 26, the ends of the second transparent substrate 2, the thick film transparent layer 20, the color filter 21, and the end of the overcoat layer 23 (that is, the end of the second substrate SUB2).

[0044] Also in the liquid crystal display device 100 according to the first modified example described above, since the end portion of the thick film transparent layer 20 is still covered by the sealing material 60 provided between the extending portions Ex1 and Ex2, in the same manner as the configurations shown in FIGS. 4 and 5, it is possible to suppress moisture from entering the thick film transparent layer 20 from the end portion of the thick film transparent layer 20 and prevent the parallax barrier pattern 40 from peeling off from the second transparent substrate 2.

[0045] (Second Modified Example) The second modified example is different from the configurations shown in FIGS. 4 and 5 in that a cover member 28 is further provided on the second transparent substrate 2 and the first transparent substrate 1 does not have an extending portion Ex1 other than the mounting portion. Hereinafter, mainly, the portions different from the configurations shown in FIGS. 4 and 5 will be described, and the description of the portions similar to the configurations shown in FIGS. 4 and 5 will be omitted.

[0046] FIG. 9 is a schematic plan view showing a configuration example of the liquid crystal display device 100 according to the second modified example. In FIG. 9, only the first transparent substrate 1, the second transparent substrate 2, the sealing material 60, and the cover member 28 among the elements constituting the liquid crystal display device 100 are illustrated.

[0047] The cover member 28 has side surfaces 28a and 28b along the X direction and side surfaces 28c and 28d along the Y direction.

[0048] In a plan view, the side surfaces 1b, 1c, and 1d of the first transparent substrate 1 overlap the side surfaces 2b, 2c, and 2d of the second transparent substrate 2, respectively. On the other hand, in a plan view, the side surface 1a of the first transparent substrate 1 does not overlap the side surface 2a of the second transparent substrate 2. The first transparent substrate 1 has an extending portion Ex1 that functions as a mounting portion between the side surfaces 1a and 2a.

[0049] In plan view, the side surfaces 28b, 28c, and 28d of the cover member 28 do not overlap with the side surfaces 1b, 1c, and 1d of the first transparent substrate 1 and the side surfaces 2b, 2c, and 2d of the second transparent substrate 2, respectively. Also, in plan view, the side surface 28a of the cover member 28 overlaps with the side surface 1a of the first transparent substrate 1 and does not overlap with the side surface 2a of the second transparent substrate 2. The cover member 28 has extension portions Ex2 between the side surfaces 28a and 2a, between the side surfaces 28b and 2b, between the side surfaces 28c and 2c, and between the side surfaces 28d and 2d.

[0050] Below the extension portion Ex2 of the cover member 28, a sealing material 60 is provided so as to cover the ends of the first transparent substrate 1 and the second transparent substrate 2 (more specifically, the ends of the thick film transparent layer 20, which will be described later) other than the ends on the mounting portion side.

[0051] In FIG. 9, the case where the side surface 28a of the cover member 28 and the side surface 1a of the first transparent substrate 1 overlap in plan view is shown, but the present invention is not limited thereto, and the side surface 28a of the cover member 28 and the side surface 1a of the first transparent substrate 1 may not overlap in plan view.

[0052] FIG. 10 is a schematic cross-sectional view of the liquid crystal display device 100 taken along the line G-H in FIG. 9. As shown in FIG. 10, a polarizing plate 26 is disposed on the surface on the Z1-direction side of the second transparent substrate 2. Also, a cover member 28 is disposed on the Z1-direction side of the polarizing plate 26 via an adhesive layer 27. As the cover member 28, for example, a glass substrate, a resin substrate, or the like can be used.

[0053] As described above, below the extension portion Ex2 of the cover member 28, a sealing material 60 is provided so as to cover the ends of the first substrate SUB1 and the ends of the second substrate SUB2 including the thick film transparent layer 20.

[0054] Also in the liquid crystal display device 100 according to the second modification described above, since there is no change in that the end portion of the thick film transparent layer 20 is covered by the sealing material 60 provided under the extending portion Ex2, similar to the configurations shown in FIGS. 4 and 5, it is possible to suppress moisture from entering the thick film transparent layer 20 from the end portion of the thick film transparent layer 20 and prevent the parallax barrier pattern 40 from peeling off from the second transparent substrate 2.

[0055] (Third Modification) The third modification is different from the configurations shown in FIGS. 4 and 5 in that the first transparent substrate 1 does not have an extending portion Ex1 other than the mounting portion. Hereinafter, mainly, the portions different from the configurations shown in FIGS. 4 and 5 will be described, and the description of the portions similar to the configurations shown in FIGS. 4 and 5 will be omitted.

[0056] FIG. 11 is a schematic plan view showing a configuration example of the liquid crystal display device 100 according to the third modification. In FIG. 11, among the elements constituting the liquid crystal display device 100, only the first transparent substrate 1, the second transparent substrate 2, and the sealing material 60 are illustrated.

[0057] In a plan view, the side surfaces 1b, 1c, 1d of the first transparent substrate 1 overlap the side surfaces 2b, 2c, 2d of the second transparent substrate 2, respectively. On the other hand, in a plan view, the side surface 1a of the first transparent substrate 1 does not overlap the side surface 2a of the second transparent substrate 2. The first transparent substrate 1 has an extending portion Ex1 that functions as a mounting portion between the side surfaces 1a and 2a.

[0058] A sealing material 60 is provided at the end portions of the first transparent substrate 1 and the second transparent substrate 2 (more specifically, the end portions of the thick film transparent layer 20, which will be described later) other than the end portions on the mounting portion side.

[0059] FIG. 12 is a schematic cross-sectional view of the liquid crystal display device 100 taken along the line I-J in FIG. 11. As shown in FIG. 12, the sealing material 60 is provided so as to cover the end of the first substrate SUB1 and the end of the second substrate SUB2 including the thick film transparent layer 20. In this configuration, since there is no portion that supports the sealing material 60 (specifically, the portion corresponding to the above-described extending portions Ex1 and Ex2), the sealing material 60 is adhered to the end of the first substrate SUB1 and the end of the second substrate SUB2 including the thick film transparent layer 20 only by the adhesive force it has.

[0060] Also in the liquid crystal display device 100 according to the third modification described above, since there is no change in that the end of the thick film transparent layer 20 is covered by the sealing material 60, similar to the configurations shown in FIGS. 4 and 5, it is possible to suppress moisture from entering the thick film transparent layer 20 from the end of the thick film transparent layer 20 and prevent the parallax barrier pattern 40 from peeling off from the second transparent substrate 2.

[0061] In each of the modifications described above, the case where the sealing material 60 is provided so as to cover the end of the thick film transparent layer 20 other than the end on the mounting portion side has been described. However, the present invention is not limited to this, and the sealing material 60 may be provided in a rectangular frame shape so as to cover the entire periphery of the end of the thick film transparent layer 20.

[0062] According to the embodiment described above, it is possible to provide a liquid crystal display device 100 with high moisture resistance.

[0063] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and its equivalent scope.
