[0009] Some embodiments will be described with reference to the drawings. The disclosure is merely an example, and those who are skilled in the art can easily conceive of appropriate modifications while maintaining the gist of the invention are naturally included in the scope of the present invention. In addition, the drawings may be schematic in width, thickness, shape, etc. of each part compared to the actual embodiment in order to make the explanation clearer, but they are merely examples and do not limit the interpretation of the present invention. In addition, in this specification and each figure, components that perform the same or similar functions as those described above with respect to the previous figures are given the same reference numerals, and duplicate detailed explanations may be omitted as appropriate.

[0010] In addition, in the drawings, an X-axis, a Y-axis, and a Z-axis that are perpendicular to each other are shown as necessary to facilitate understanding. The direction along the X-axis is called the first direction X, the direction along the Y-axis is called the second direction Y, and the direction along the Z-axis is called the third direction Z. Viewing various elements parallel to the third direction Z is called a planar view.

[0011] 1 is a schematic plan view showing a configuration example of the display device DSP. The display device DSP according to this embodiment is a liquid crystal display device. The display device DSP includes a display panel PNL, a polarizing plate 40, a conductive adhesive 50, conductive layers 61 and 62, electrodes 71 and 72, connecting members 81 and 82, moisture-proofing agents 91 and 92, and a cover member CM. The display device DSP also includes an illumination device that illuminates the display panel PNL, as described later.

[0012] The display panel PNL includes a first substrate SUB1 and a second substrate SUB2. The second substrate SUB2 faces the first substrate SUB1 in the third direction Z. The first substrate SUB1 and the second substrate SUB2 are formed in the shape of a flat plate parallel to the XY plane.

[0013] The display panel PNL has a display area DA and a peripheral area SA. The display area DA is an area for displaying an image. The display area DA has a plurality of pixels PX arranged in a matrix in a first direction X and a second direction Y. In the illustrated example, the first substrate SUB1, the second substrate SUB2, and the display area DA are formed in a rectangular shape extending in the first direction X. The peripheral area SA surrounds the display area DA. The peripheral area SA has an extension portion Ex. The extension portion Ex is a portion of the first substrate SUB1 that does not overlap with the second substrate SUB2, and is an area for mounting a flexible printed circuit board or an IC chip.

[0014] The first substrate SUB1 has a first side S1 extending in a first direction X, and a second side S2 and a third side S3 each extending in a second direction Y. The second substrate SUB2 has a fourth side S4 extending in the first direction X. The first side S1 corresponds to the side on the extension portion Ex side. The third side S3 is located on the opposite side of the second side S2 across the display area DA. The fourth side S4 is located between the display area DA and the first side S1 in a plan view. The extension portion Ex is located between the first side S1 and the fourth side S4.

[0015] As shown in an enlarged view in FIG. 1, the pixels PX include a switching element SW, a pixel electrode PE, a common electrode CE, a liquid crystal layer LC, and the like. The switching element SW is, for example, a thin film transistor (TFT), and is electrically connected to a scanning line GL and a signal line SL. The scanning line GL is electrically connected to the switching element SW in each of the pixels PX aligned in the first direction X. The signal line SL is electrically connected to the switching element SW in each of the pixels PX aligned in the second direction Y. The pixel electrode PE is electrically connected to the switching element SW. Each of the pixel electrodes PE faces the common electrode CE, and drives the liquid crystal layer LC by an electric field generated between the pixel electrode PE and the common electrode CE. The capacitance CS is formed, for example, between an electrode having the same potential as the common electrode CE and an electrode having the same potential as the pixel electrode PE. As will be described in detail later, the scanning line GL, the signal line SL, the switching element SW, the pixel electrode PE, and the common electrode CE are provided on a first substrate SUB1.

[0016] The polarizing plate 40 overlaps the display area DA in plan view. In the example of FIG. 1, each side of the polarizing plate 40 is located between the display area DA and each side of the second substrate SUB2. The polarizing plate 40 is attached to the second substrate SUB2 by a conductive adhesive 50. In the example of FIG. 1, the size of the polarizing plate 40 is equal to the size of the conductive adhesive 50. The polarizing plate 40 and the conductive adhesive 50 have a fifth side S5 located on the second side S2 side and a sixth side S6 located on the third side S3 side. The fifth side S5 does not overlap the second side S2 and is located between the second side S2 and the display area DA. The sixth side S6 does not overlap the third side S3 and is located between the third side S3 and the display area DA.

[0017] The conductive layer 61 and the conductive layer 62 are located between the display area DA and the fourth side S4. The conductive layer 61 and the conductive layer 62 are arranged in the first direction X with a gap GP therebetween. That is, the conductive layer 61 and the conductive layer 62 are spaced apart from each other. In the example of FIG. 1, the conductive layer 61 overlaps the second side S2 and the fourth side S4 in a plan view. The conductive layer 62 overlaps the third side S3 and the fourth side S4 in a plan view. Note that the conductive layer 61 may be spaced apart from the second side S2 and the fourth side S4, and the conductive layer 62 may be spaced apart from the third side S3 and the fourth side S4.

[0018] The conductive layer 61 is formed in a rectangular shape having a long side S61 extending in the first direction X. The conductive layer 62 is formed in a rectangular shape having a long side S62 extending in the first direction X. In the example of Fig. 1, the long sides S61 and S62 overlap with the fourth side S4 in a plan view. Furthermore, the width of each of the conductive layers 61 and 62 in the first direction X is larger than the gap GP in the first direction X.

[0019] The electrodes 71 and 72 are each disposed between the first side S1 and the fourth side S4 (extension portion Ex) in a plan view. The electrode 71 is located on the second side S2 side, and the electrode 72 is located on the third side. The electrodes 71 and 72 are each connected to the ground potential of the flexible printed circuit board and the IC chip.

[0020] The connection member 81 electrically connects the conductive layer 61 and the electrode 71. The connection member 82 electrically connects the conductive layer 62 and the electrode 72.

[0021] The moisture-proofing agent 91 is located between the second side S2 and the fifth side S5 in a planar view. The moisture-proofing agent 91 covers the conductive layer 61 between the second side S2 and the fifth side S5 and is in contact with the conductive adhesive 50. The moisture-proofing agent 92 is located between the third side S3 and the sixth side S6 in a planar view. The moisture-proofing agent 92 covers the conductive layer 62 between the third side S3 and the sixth side S6 and is in contact with the conductive adhesive 50.

[0022] The cover member CM faces the polarizing plate 40 in the third direction Z, as indicated by a two-dot chain line. The cover member CM covers the entire surface of the display panel PNL in a plan view. The cover member CM is made of a transparent material such as glass or plastic. The cover member CM may also include a touch panel or the like.

[0023] 2 is a schematic cross-sectional view showing an example of the configuration of the display device DSP. The display panel PNL includes the above-mentioned first substrate SUB1 and second substrate SUB2, and a liquid crystal layer LC.

[0024] The first substrate SUB1 includes a transparent substrate 10, insulating layers 11 and 12, a common electrode CE, a plurality of pixel electrodes PE, and an alignment film AL1. The first substrate SUB1 is disposed above the lighting device BL. The insulating layer 11 is disposed on the transparent substrate 10. The common electrode CE is disposed on the insulating layer 11 across a plurality of pixels PX. The insulating layer 12 is disposed on the common electrode CE. A plurality of pixel electrodes PE are disposed on the insulating layer 12 for each pixel PX. The alignment film AL1 covers the plurality of pixel electrodes PE and the insulating layer 12. The scanning lines GL, the signal lines SL, and the switching elements SW shown in FIG. 1 are disposed between the transparent substrate 10 and the common electrode CE.

[0025] The second substrate SUB2 includes a transparent substrate 20 and an alignment film AL2. The second substrate SUB2 is disposed above the first substrate SUB1. The alignment film AL2 is disposed below the transparent substrate 20. Although not shown, a light-shielding layer, a color filter layer, an overcoat layer, and the like may be further provided on the second substrate SUB2. However, the color filter layer may be provided on the first substrate SUB1.

[0026] The liquid crystal layer LC is disposed between the first substrate SUB1 and the second substrate SUB2. In the example of Fig. 2, the liquid crystal layer LC is disposed between the alignment film AL1 and the alignment film AL2.

[0027] The display device DSP further includes the above-mentioned polarizing plate 40 and cover member CM, a polarizing plate 30, transparent adhesives AD1 and AD2, and a conductive adhesive 50. The polarizing plate 30 is disposed between the lighting device BL and the transparent substrate 10, and is adhered to the lower surface of the first substrate SUB1 with a transparent adhesive AD1. The polarizing plate 40 faces the second substrate SUB2. The polarizing plate 40 is disposed between the transparent substrate 20 and the cover member CM, and is adhered to the upper surface of the second substrate SUB2 with a conductive adhesive 50. The polarization axes of the polarizing plate 30 and the polarizing plate 40 are orthogonal to each other in, for example, the XY plane.

[0028] The cover member CM is adhered to the upper surface of the polarizing plate 40 by a transparent adhesive AD2. For example, an OCA (Optical Clear Adhesive) or an OCR (Optical Clear Resin) may be used as the transparent adhesive AD1 and the transparent adhesive AD2.

[0029] The transparent substrate 10 and the transparent substrate 20 are insulating substrates such as glass or plastic. The insulating layer 11 is formed of a transparent insulating material. In one example, the insulating layer 11 includes an inorganic insulating layer and an organic insulating layer. The insulating layer 12 is formed of a transparent inorganic insulating material such as silicon nitride (SiNx).

[0030] The common electrode CE and the pixel electrodes PE are formed of a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO). The alignment films AL1 and AL2 are horizontal alignment films having an alignment regulating force along the XY plane. The alignment films AL1 and AL2 may be photo-alignment films that are given an alignment regulating force by being irradiated with ultraviolet light, or may be alignment films that have been subjected to a rubbing treatment.

[0031] FIG. 3 is a schematic cross-sectional view of the display device DSP taken along the line AA' in FIG. The display panel PNL further includes a seal SE. The seal SE bonds the first substrate SUB1 and the second substrate SUB2 together. The liquid crystal layer LC is sealed by the seal SE.

[0032] The conductive layer 61 and the conductive layer 62 are each disposed between the second substrate SUB2 and the conductive adhesive 50. Specifically, the conductive layer 61 and the conductive layer 62 are each disposed on the second substrate SUB2. Furthermore, each of the conductive layer 61 and the conductive layer 62 is partially covered with the conductive adhesive 50. A portion of an area of ​​the conductive layer 61 that is not covered with the conductive adhesive 50 is covered with a connection member 81. A portion of an area of ​​the conductive layer 62 that is not covered with the conductive adhesive 50 is covered with a connection member 82. The connection member 81 and the connection member 82 are spaced apart from the conductive adhesive 50, but may be in contact with the conductive adhesive 50.

[0033] The electrodes 71 and 72 are formed on a first substrate SUB1. In the example of Fig. 3, a portion of the electrode 71 is covered by a connection member 81. A portion of the electrode 72 is covered by a connection member 82. However, the electrode 71 may be entirely covered by the connection member 81. The electrode 72 may be entirely covered by the connection member 82.

[0034] As described above, the connection member 81 electrically connects the conductive layer 61 and the electrode 71. The connection member 82 electrically connects the conductive layer 62 and the electrode 72. The conductive adhesive 50 is electrically connected to the electrodes 71 and 72 via the conductive layers 61 and 62, the connection member 81 and the connection member 82. This makes it possible to form a discharge path from the conductive adhesive 50 to the electrodes 71 and 72 at the ground potential, and makes it possible to suppress undesired charging of the second substrate SUB2. This makes it possible to suppress a decrease in display quality caused by charging.

[0035] The conductive layer 61 and the conductive layer 62 are each formed of a transparent oxide. Examples of the transparent oxide include indium tin oxide (ITO) and indium zinc oxide (IZO). The resistance value of each of the conductive layer 61 and the conductive layer 62 is equal to or lower than the resistance value of the conductive adhesive 50.

[0036] The connection members 81 and 82 are each formed by applying a conductive paste, for example. The connection members 81 and 82 are each formed of a material containing silver, for example.

[0037] FIG. 4 is a schematic cross-sectional view of the display device DSP taken along the line BB' in FIG. The conductive layer 61 has an upper surface 61U (first upper surface) exposed from the conductive adhesive 50. The conductive layer 62 has an upper surface 62U (second upper surface) exposed from the conductive adhesive 50. The polarizing plate 40 has a first side surface 41 located on the second side S2 side and a second side surface 42 located on the third side S3 side. A corner formed by the upper surface 61U of the conductive layer 61 exposed from the conductive adhesive 50 and the first side surface 41 of the polarizing plate 40 is defined as a first corner CN1, and a corner formed by the upper surface 62U of the conductive layer 62 exposed from the conductive adhesive 50 and the second side surface 42 of the polarizing plate 40 is defined as a second corner CN2.

[0038] The moisture-proofing agent 91 covers the first corner CN1. In the example of Fig. 4, the moisture-proofing agent 91 is filled in a space SP1 surrounded by the conductive layer 61, the polarizing plate 40, and the cover member CM. In the example of Fig. 4, the moisture-proofing agent 91 contacts the conductive layer 61, the polarizing plate 40 (first side surface 41), the conductive adhesive 50, the transparent adhesive AD2, and the cover member CM, but is not limited to this example. The moisture-proofing agent 91 is disposed at the first corner CN1 so as to cover at least the conductive layer 61 and the conductive adhesive 50.

[0039] The moisture-proofing agent 92 covers the second corner portion CN2. In the example of Fig. 4, the moisture-proofing agent 92 is filled in a space SP2 surrounded by the conductive layer 62, the polarizing plate 40, and the cover member CM. In the example of Fig. 4, the moisture-proofing agent 92 is in contact with the conductive layer 62, the polarizing plate 40 (second side surface 42), the conductive adhesive 50, the transparent adhesive AD2, and the cover member CM, but is not limited to this example. The moisture-proofing agent 92 is disposed at the second corner portion CN2 so as to cover at least the conductive layer 62 and the conductive adhesive 50.

[0040] The moisture-proofing agent 91 and the moisture-proofing agent 92 may be, for example, a fluorine-based resin, an olefin-based resin, a urethane-based resin, an acrylic-based resin, or a silicon-based resin.

[0041] In the above example, conductive layer 61 corresponds to the first conductive layer, conductive layer 62 corresponds to the second conductive layer, electrode 71 corresponds to the first electrode, electrode 72 corresponds to the second electrode, connecting member 81 corresponds to the first connecting member, connecting member 82 corresponds to the second connecting member, moisture-proofing agent 91 corresponds to the first moisture-proofing agent, and moisture-proofing agent 92 corresponds to the second moisture-proofing agent.

[0042] According to this embodiment, the conductive layers 61 and 62, the electrodes 71 and 72, the connection members 81 and 82, and the conductive adhesive 50 are electrically connected to each other. The conductive layers 61 and 62 are separated from each other by a gap GP. Therefore, when a voltage is applied between the electrodes 71 and 72, for example, a current flows through the electrode 71, the connection member 81, the conductive layer 61, the conductive adhesive 50, the conductive layer 62, the connection member 82, and the electrode 72 in this order.

[0043] On the other hand, for example, when the conductive layers 61 and 62 are in contact with each other, the resistance values ​​of the conductive layers 61 and 62 are lower than the resistance value of the conductive adhesive 50, so that almost no current flows through the conductive adhesive 50, and a large current flows through the conductive layers 61 and 62. This makes it difficult to measure the resistance value of the conductive adhesive 50.

[0044] In contrast, in the display device DSP according to this embodiment, the conductive layer 61 and the conductive layer 62 are spaced apart from each other and are electrically connected to each other via the conductive adhesive 50. Therefore, compared to when the conductive layer 61 and the conductive layer 62 are in contact with each other, when the conductive layer 61 and the conductive layer 62 are spaced apart from each other, a larger current flows through the conductive adhesive 50. Therefore, the resistance value of the conductive adhesive 50 can be reliably measured.

[0045] Furthermore, the moisture-proofing agent 91 covers the first corner portion CN1, and the moisture-proofing agent 92 covers the second corner portion CN2. Therefore, the moisture-proofing agents 91 and 92 can prevent moisture from entering the contact surface between the conductive layer 61 and the conductive adhesive 50 and the contact surface between the conductive layer 62 and the conductive adhesive 50. Therefore, corrosion of the conductive layers 61 and 62 due to moisture can be suppressed.

[0046] Next, other configuration examples of the display device DSP will be described. The same or similar elements as those of the display device DSP described above are given the same reference numerals, and duplicated explanations will be omitted. Note that the other configuration examples of the display device DSP described below can also achieve the same effects as those described above.

[0047] 5 is a schematic plan view showing another configuration example of the display device DSP. The conductive layer 61 is formed in an L-shape having a first portion 61A extending in the first direction X and a second portion 61B extending from the first portion 61A in the second direction Y. The conductive layer 62 is formed in an L-shape having a third portion 62A extending in the first direction X and a fourth portion 62B extending from the third portion 62A in the second direction Y. The first portion 61A and the third portion 62A are each located between the display area DA and the fourth side S4. The second portion 61B is located between the display area DA and the second side S2. The fourth portion 62B is located between the display area DA and the third side S3.

[0048] The conductive adhesive 50 overlaps a portion of each of the first portion 61A, the second portion 61B, the third portion 62A, and the fourth portion 62B in a plan view. The moisture-proofing agent 91 overlaps a portion of each of the first portion 61A and the second portion 61B in a plan view. The moisture-proofing agent 92 overlaps a portion of each of the third portion 62A and the fourth portion 62B in a plan view.

[0049] 5, by forming the conductive layers 61 and 62 in an L-shape, the contact area between the conductive layers 61 and 62 and the conductive adhesive 50 is increased compared to when the conductive layers 61 and 62 are formed in a rectangular shape. Therefore, the contact resistance between the conductive layers 61 and 62 and the conductive adhesive 50 can be reduced.

[0050] FIG. 6 is a schematic plan view showing still another configuration example of the display device DSP. The widths of the first portion 61A and the third portion 62A along the second direction Y are defined as width W1 and width W3, respectively. The widths of the second portion 61B and the fourth portion 62B along the first direction X are defined as width W2 and width W4, respectively. In the example of FIG. 6, width W1 is larger than width W2, and width W3 is larger than width W4. Therefore, the distance between the display area DA and the second side S2, and the distance between the display area DA and the third side S3 can be made smaller. Therefore, the frame of the display device DSP can be made narrower.

[0051] All display devices that can be implemented by those skilled in the art through appropriate design modifications based on the display devices described above as the embodiments of the present invention belong to the scope of the present invention as long as they include the gist of the present invention.

[0052] Within the scope of the concept of the present invention, a person skilled in the art may conceive of various modifications, and such modifications are also understood to fall within the scope of the present invention. For example, those in which a person skilled in the art appropriately adds or removes components or modifies the design of the above-mentioned embodiment, or adds or omits steps or modifies conditions, are also included in the scope of the present invention as long as they include the gist of the present invention.

[0053] Furthermore, with regard to other effects and advantages brought about by the aspects described in the above-mentioned embodiments, those which are obvious from the description in this specification or which can be appropriately thought up by a person skilled in the art are naturally understood to be brought about by the present invention.
