Description

  The present invention relates to a display device and a display device panel suitable for a liquid crystal or organic light emitting display device, and more particularly to a display device and a display device panel effective for a thin type.

A display panel such as a liquid crystal display or an organic light emitting display device has a display element such as a liquid crystal or organic light emitting (organic EL (electroluminescence)) element provided between two substrates on which a thin film device or the like is formed. It is built into the product as a module bonded to a frame.
JP-A-2005-49450

  Glass is generally used as the material of the substrate of such a display panel, but it is very brittle as a problem, and in particular, consideration for impact resistance or drop resistance is required. In conventional modules, the LCD panel is often directly bonded to the frame with double-sided adhesive tape, etc. When the module receives an external impact, the impact is transmitted almost directly to the LCD panel and breaks. There was also a risk. Also, one of the two substrates is provided with an external connection area for input / output of image signals and the like, and this external connection area is generally composed of only one glass substrate. Compared with other parts composed of two glass substrates, the strength is the weakest at about half, and further consideration has been desired for cracks and the like.

  In addition, when the display panel is bonded to the frame, the corners of the display panel (two intersecting sides) are placed in contact with the frame for horizontal positioning. There was a risk of it occurring. It is also possible to position the display panel in the horizontal direction using special equipment and avoid contact between the side of the display panel and the frame. There was a problem that complete panel protection was difficult. In addition, due to equipment accuracy, it is necessary to secure the clearance with the frame more than necessary over the entire periphery of the display panel, and the frame has to be taken wider than necessary. Furthermore, the assembly cost also increases, and there is a problem that costs for handling and construction of equipment are required.

  Incidentally, Patent Document 1 discloses a configuration in which the polarizing plate is made larger than the outer shape of the glass substrate and the protruding portion of the polarizing plate is bonded to the frame. However, in this conventional structure, only the impact applied to the panel main surface is considered, and sufficient measures are not taken against the horizontal impact on the panel end surface (side surface). There was a problem that damage could not be prevented sufficiently. Further, in order to position the display panel in the planar direction, the weakest part composed of only one glass substrate is directly brought into contact with the frame, so that the display panel is extremely weak against impact. Even if positioning was performed using a side surface constituted by two glass substrates on the other side, contact with the frame could not be completely avoided, and there was a risk of damage to the display panel.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a display device and a display device panel capable of buffering shocks from all directions applied to the display panel and reliably protecting the display panel. There is to do.

The display device according to the present invention is elastically deformable having a rectangular display panel in which a drive substrate and a counter substrate are arranged to face each other, and an extended portion which is bonded to the counter substrate and protrudes from the counter substrate on at least two sides of the display panel. A counter-side support plate, an elastically deformable drive-side support plate that is bonded to the drive substrate and has an extended portion that protrudes from the drive substrate on at least two sides of the display panel, surrounds the side surface of the display panel, and and a rectangular frame having a first gap between the four sides, one of the extensions of the opposing side support plate and driven-side supporting plate is fixed to the frame beyond the first gap, the counter side support The 2nd clearance gap smaller than a 1st clearance gap is provided between the other expansion part and the frame among the board and the drive side support plate .

A display device panel according to the present invention has a rectangular display panel in which a drive substrate and a counter substrate are arranged to face each other, and an elastic deformation having an extended portion that is bonded to the counter substrate and protrudes from the counter substrate on at least two sides of the display panel. A counter-side support plate, and a drive-side support plate that is bonded to the drive substrate and has elastically deformable drive-side support plates that extend from the drive substrate on at least two sides of the display panel. the protrusion amount of extension of one of the supporting plates is much larger than the width of the first gap provided between the four sides of the rectangular frame and the display panel surrounding the side surface of the display panel, the opposing side support plate drive The amount of protrusion of the other extended portion of the side support plate is smaller than the width of the first gap .

In the display device of the present invention or the display device panel of the present invention, the initial impact from each direction applied to the display panel is buffered and absorbed by elastic deformation of the extended portion of the opposite side support plate or drive side support plate. The In addition, a first gap is provided between the four sides of the display panel and the frame, and one of the opposing side support plate and the drive side support plate is fixed to the frame beyond the first gap. . On the other hand, a second gap smaller than the first gap is provided between the other extended portion of the opposing side support plate and the driving side support plate and the frame, and the opposing side support plate or the driving side support plate The other extension part protrudes from the end surface of the display panel. This avoids direct contact between the side surface of the display panel and the frame. Therefore, cracking of the display panel due to impact is reliably suppressed.

According to the display device of the present invention or the display device panel of the present invention, the first gap is provided between the four sides of the display panel and the frame, and one of the opposing side support plate and the drive side support plate is provided. The extension portion is fixed to the frame beyond the first gap, while the second support plate and the drive side support plate are smaller than the first gap between the other extension portion and the frame. A gap is provided so that the other extension of the opposing support plate or drive support plate protrudes from the end face of the display panel, so that shocks from all directions applied to the display panel are buffered and the display panel is protected from damage. It can be surely protected.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
1 and 2 show a cross-sectional configuration of the liquid crystal display device according to the first embodiment of the present invention. This liquid crystal display device is a thin module used for a digital camera, a PDA (Personal Digital Assistants), a mobile phone, or the like. For example, a rectangular liquid crystal display panel 100, and an upper surface (viewing surface) and a lower surface of the liquid crystal display panel 100 are used. And the opposite side polarizing plate 200 and the driving side polarizing plate 300, and a rectangular frame 400 surrounding the side surface of the liquid crystal display panel 100. Here, the “thin module” is one in which the thickness of one of the two substrates constituting the display panel is thinner than the thickness of the counter-side polarizing plate 200 ((one-side substrate thickness) <(opposite side). Times the polarizing plate thickness)).

  The liquid crystal display panel 100 includes a liquid crystal (not shown) between the driving substrate 110 and the counter substrate 120, and the type and driving method of the liquid crystal are not particularly limited. In addition, the liquid crystal display panel 100 includes an overlapping region 100A where the driving substrate 110 and the counter substrate 120 are overlapped, and an external connection region 100B where the driving substrate 110 protrudes from the counter substrate 120. The external connection region 100B is provided along one side of the drive substrate 110, and is connected to an FPC (Flexible Printed Circuit) 130 for external connection.

  The drive substrate 110 is a glass substrate provided with a drive circuit, a pixel electrode corresponding to each pixel, and an alignment film (both not shown). The counter substrate 120 is a glass substrate provided with a color filter, a common electrode, and an alignment film (all not shown).

  The counter-side polarizing plate 200 has extended portions 200 </ b> A that protrude from the counter substrate 120 on three sides except one side where the external connection region 100 </ b> B of the liquid crystal display panel 100 is provided. The protruding amount L1 of the extended portion 200A is larger than the first gap G1 provided between the frame 400 and the display panel 100, as will be described later. In addition, as shown in FIG. 3A, the opposite-side polarizing plate 200 includes an adhesive layer 201 for bonding to the opposite substrate 120 in order from the opposite substrate 120 side, a protective layer 202 made of synthetic resin, An iodine-based polarizer 203 and a protective layer 204 made of a synthetic resin are laminated and have elastic deformation characteristics as a whole. Here, the counter-side polarizing plate 200 corresponds to a specific example of the “counter-side support plate” of the present invention.

  The drive-side polarizing plate 300 has extended portions 300 </ b> A that protrude from the drive substrate 110 on three sides except one side where the external connection region 100 </ b> B of the liquid crystal display panel 100 is provided. The protruding amount L2 of the extended portion 300A is smaller than the first gap G1 provided between the frame 400 and the display panel 100, as will be described later. As shown in FIG. 3B, the driving-side polarizing plate 300 includes, in order from the driving substrate 110 side, an adhesive material layer 301, a protective layer 302, a polarizer 303, and a protective layer 304 for bonding to the driving substrate 110. , An adhesive material layer 305 and a brightness enhancement film 306 are laminated and have elastic deformation characteristics as a whole. Here, the driving side polarizing plate 300 corresponds to a specific example of the “driving side support plate” of the present invention.

  The frame 400 shown in FIGS. 1 and 2 is made of, for example, a resin (plastic) having high reflection characteristics, stainless steel, or the like. The frame 400 has a first gap G1 between the four sides of the display panel 100, and the extended portion 200A of the opposing-side polarizing plate 200 is fixed to the frame 400 beyond the first gap G1. Yes. As a result, in this liquid crystal display device, it is possible to buffer the impact from any direction applied to the display panel 100 and to reliably protect the display panel 100 from damage.

  It is preferable that the extended portion 200 </ b> A of the counter-side polarizing plate 200 is fixed to the frame 400 at three or more points. This is because the influence of torsional deformation of the frame 400 caused by drop impact or the like can be alleviated and the display panel 100 can be more reliably protected.

  A fixing portion 200 </ b> B to the frame 400 is provided in the extended portion 200 </ b> A of the counter-side polarizing plate 200. The fixing portion 200B may be provided with a frame fixing adhesive layer made of a material different from that of the adhesive material layer 201, or an attachment structure different from the adhesive material layer 201, for example, a frame 400 shown in FIG. Two or more such claws 410 may be provided, or both of them may be provided. In this way, the pressure-sensitive adhesive layer 201 can be selected in consideration of only the appropriate value of the adhesive strength between the display panel 100 and the counter-side polarizing plate 200 from the viewpoint of temperature characteristics and the like. Further, it is possible to select the material or the structure of the fixing portion 200B so that the display panel 100 can be easily detached from the frame 400 without being damaged during repair. The fixing part 200B may be provided with the same adhesive material layer as the adhesive material layer 201 from the viewpoint of reducing the thickness of the liquid crystal display device.

  A second gap G2 smaller than the first gap G1 is provided between the extended portion 300A of the driving side polarizing plate 300 and the frame 400 (G1> G2 ≧ 0). As described above, since the extended portion 300A of the driving-side polarizing plate 300 protrudes from the end surface of the display panel 100, direct contact between the end surface of the display panel 100 and the frame 400 can be avoided and the end surface of the display panel 100 can be prevented from impact. Can be protected. Further, as will be described later, in the manufacturing process, the display panel 100 and the frame 400 can be aligned in the planar direction using the extended portion 300 </ b> A of the driving side polarizing plate 300.

  A light source 500 made of LEDs (Light Emitting Diodes), a light guide plate (light guide) 600, and an optical sheet 610 are provided on the drive side polarizing plate 300 side of the display panel 100. The light source 500 and the light guide plate 600 are provided on a bottom plate 400 </ b> A that covers the lower portion of the frame 400. The optical sheet 610 is inserted between the light guide plate 600 and the driving-side polarizing plate 300, and is a diffusion sheet or a prism sheet for improving optical characteristics. A third gap G <b> 3 is provided between the driving side polarizing plate 300 and the optical sheet 610, and the impact on the display panel 100 caused by a load on the display panel 100 and a drop can be reduced. It is like that. The optical sheet 610 may be provided as necessary, and when the optical sheet 610 is not provided, the above-described third gap G3 is provided between the driving side polarizing plate 300 and the light guide plate 600. That's fine.

The third gap G3 is preferably larger than the amount of bending of the opposing polarizing plate 200 that occurs when the third gap G3 is dropped. This is because the buffering effect in the thickness direction by the extended portion 200 </ b> A of the counter-side polarizing plate 200 is maximized by avoiding collision due to bending. Here, the amount of deflection of the counter-side polarizing plate 200 is W, the mass supported by the counter-side polarizing plate 200, and the impact to be guaranteed by dropping or the like. / S ² ), if the impact strength applied is determined by [W × G] as is well known, it can be easily estimated by actually measuring the amount of deflection when the impact strength equivalent is applied to the opposing polarizing plate 200. is there.

  Since the setting of the third gap G3 is directly linked to the thickness of the module, it may be assumed that a sufficient gap G3 cannot be secured by giving priority to thinning. However, even in such a case, while the gap G3 becomes 0 in a state of receiving an impact, the buffering effect of the opposing polarizing plate 200 is exhibited, and the impact on the display panel 100 can be reduced. Further, in the state of receiving an impact, the member (the optical sheet 610 or the light guide plate 600) facing the drive side polarizing plate 300 with the gap G3 in between is also subjected to the impact and bends in the same direction. If it is assumed that the elastic deformation characteristics of the member to be counteracted and the counter-side polarizing plate 200 can be made the same, the gap G3 can be set to the minimum necessary (≈0), and the buffering effect can be expected to the maximum.

  Such a liquid crystal display device can be manufactured as follows, for example.

  First, the drive substrate 110 and the counter substrate 120 are respectively formed, and liquid crystal is sealed between them to form the liquid crystal display panel 100.

  Next, the counter-side polarizing plate 200 is bonded to the counter substrate 120, and the driving-side polarizing plate 300 is bonded to the driving substrate 110 at predetermined positions, whereby a display device panel is manufactured. The predetermined position here is a position where the first gap G1 and the second gap G2 described above are obtained between the frame 400 and the frame 400. That is, as shown in FIG. 5, the protrusion amount L1 of the expansion portion 200A is made larger than the first gap G1 provided between the frame 400 and the display panel 100, while the protrusion amount L2 of the expansion portion 300A is set. The second gap G2 smaller than the first gap G1 is formed between the extended portion 300A and the frame 400 by making it smaller than the first gap G1. Thereby, the side surface of the liquid crystal display panel 100 can be protected by the extended portion 200A of the counter-side polarizing plate 200 and the extended portion 300A of the driving-side polarizing plate 300, and the convenience of transportation and handling of the liquid crystal display panel 100 is remarkably improved. Can be made.

  After the opposite-side polarizing plate 200 and the driving-side polarizing plate 300 are bonded to the liquid crystal display panel 100, a first gap G1 and a second gap G2 are formed between the liquid crystal display panel 100 and the frame 400. Are aligned, and the extended portion 200 </ b> A of the opposite-side polarizing plate 200 is fixed to the frame 400. At that time, by aligning at least two intersecting outer shapes of the extended portion 300 </ b> A of the driving side polarizing plate 300 with the frame 400, the display panel 100 can be easily aligned at the same time as being not in contact with the frame 400. On the other hand, in Patent Document 1 described above, the end face of the panel is brought into direct contact with the frame and the horizontal alignment is performed. Therefore, an impact is applied to the panel during the alignment and there is a risk of damage.

  In this liquid crystal display device, light from the light source 500 passes through the light guide plate 600, the optical sheet 610, the driving side polarizing plate 300, the driving substrate 110, the liquid crystal, the counter substrate 120, and the counter side polarizing plate 200. Is emitted. Here, the first gap G1 is provided between the four sides of the display panel 100 and the frame 400, and the extended portion 200A of the opposing-side polarizing plate 200 is fixed to the frame 400 beyond the first gap G1. Has been. Therefore, the display panel 100 has a structure supported only by the counter-side polarizing plate 200. Thereby, the initial impact from each direction applied to the display panel 100 is buffered and absorbed by the elastic deformation of the extended portion 200 </ b> A of the counter-side polarizing plate 200. Therefore, cracking of the display panel 100 due to impact is reliably suppressed.

  For example, as shown in FIG. 6, this liquid crystal display device is housed in a chassis 700 made of a highly rigid material such as an alloy containing magnesium (Mg), and at the upper surface (viewing surface) with a transparent plate 800 made of plastic or the like. And is housed in an outer casing 900 made of a highly rigid material such as polycarbonate containing glass fiber, whereby a liquid crystal display unit of an electronic device such as a cellular phone can be configured. Note that a light shielding tape 810 that covers a frame space around the display area may be attached between the counter-side polarizing plate 200 and the transparent plate 800. Instead of the light shielding tape 810, a light shielding film may be provided on the transparent plate 800 by printing.

  In such an electronic device, for example, in the case of FIG. 6, when the transparent plate 800 is strongly pressed and bent from the outside by a finger or the like, first, the opposing side polarizing plate 200 is bent substantially by the gap G3 amount described above, and at the same time substantially the same A large amount of bending also occurs in the display panel 100 and the driving-side polarizing plate 300. Finally, a load applied from the outside is supported by the chassis 700 via the optical sheet 610, the light guide plate 600, and the like. The display panel 100 is prevented from being bent and the like as well as being not bent. Further, the display panel 100 also has sufficient elastic deformation characteristics, and is an amount of deflection within the elastic limit (substantially synonymous with until it breaks), so when the load is removed, it returns to its original normal state.

  As described above, in the present embodiment, the first gap G1 is provided between the four sides of the display panel 100 and the frame 400, and the extended portion 200A of the counter-side polarizing plate 200 extends beyond the first gap G1. Since the frame 400 is fixed to the frame 400, it is possible to alleviate impacts from all directions from the outside and to reliably protect the display panel 100 from damage. Further, there is no need to add a special cushioning member, and a double-sided adhesive tape for fixing the display panel 100 and the frame 400 is not required, and therefore the thickness is not increased, which is extremely advantageous for reduction in thickness and weight. At the same time, it is effective for cost reduction. Further, the space for fixing the double-sided adhesive tape for fixing the display panel 100 and the frame 400 becomes unnecessary, and a design that minimizes the frame space is also possible. In addition, it is possible to make the bonding area of the display panel 100, the counter-side polarizing plate 200, and the driving-side polarizing plate 300 substantially the same as the display panel 100, and the impact concentration on the display panel 100 can be avoided to the maximum. It can be set as a structure, and the crack of the display panel 100 by an impact, etc. can be suppressed reliably.

  In particular, since the second gap G2 smaller than the first gap G1 is provided between the extended portion 300A of the driving side polarizing plate 300 and the frame 400, the end surface of the display panel 100 and the frame 400 are directly connected. Contact can be avoided and the end face of the display panel 100 can be protected from impact. In the manufacturing process, the display panel 100 and the frame 400 can be aligned in the planar direction using at least two intersecting sides of the extended portion 300 </ b> A of the driving side polarizing plate 300.

  In the above embodiment, as shown in FIG. 2, the case where the drive-side polarizing plate 200 is extended to the external connection region 100B to reinforce the external connection region 100B of the drive substrate 110 has been described. -For reasons of space, etc., the minimum range necessary for optics may be used. In this case, as will be described later, it is desirable to reinforce the counter-side polarizing plate 200 by extending it to the external connection region 100B.

  For example, FIG. 2 shows the case where the counter-side polarizing plate 200 is not provided in the external connection region 100B. However, if the thickness of the FPC 130 is equal to or less than the thickness of the counter substrate 120, the driving-side polarizing plate 300 is external. When the connection region 100B is not covered, the counter-side polarizing plate 200 may be extended to the external connection region 100B by attaching the counter-side polarizing plate 200 after mounting the FPC 130. As a result, it is possible to also serve as peeling protection between the FPC 130 and the drive substrate 110. Furthermore, as shown in FIG. 7, if UV curable resin 140 or the like is applied between the portion extending to the external connection region 100B of the opposite-side polarizing plate 200 and the FPC 130 and the driving substrate 110, the highest strength is obtained. It is possible to greatly improve the strength of the driving substrate 110 and the peel strength of the FPC 130 in the weak external connection region 100B. In addition, in this case, by extending the counter-side polarizing plate 200 to the external connection region 100B, it becomes easier to control the thickness due to the coating amount of the ultraviolet curable resin 140 than in the past. It is valid.

  When the thickness of the FPC 130 is as described above (the thickness of the counter substrate 120 or less), it is naturally possible to extend both the driving side polarizing plate 300 and the counter side polarizing plate 200 to the external connection region 100B. It is also possible to apply the ultraviolet curable resin 140. Thereby, reinforcement of the external connection region 100B can be further ensured.

  Further, not only the opposing side polarizing plate 200 extends to the external connection region 100B, but also an extended portion 200A is provided so as to protrude from the external connection region 100B, and the opposing side polarizing plate 200 is fixed to and supported by the frame 400. Good. As a result, the impact can be reliably mitigated and the dustproof can be improved. In this case, it is possible to provide the FPC 130 out of the hole while providing a hole in the frame 400 and providing the receiving part for the opposite side polarizing plate 200. However, as shown in FIG. In addition, the FPC 130 may be taken out from the FPC outlet 420 between the extended portion 200 </ b> A of the counter-side polarizing plate 200 and the frame 400.

(Second Embodiment)
FIG. 9 illustrates a cross-sectional configuration of a liquid crystal display device according to the second embodiment of the present invention. In this liquid crystal display device, the liquid crystal display panel 100 is disposed in the frame 400 with the drive substrate 110 side as an upper surface (viewing surface), and the extended portion 300A of the drive side polarizing plate 300 extends beyond the first gap G1. Except for being fixed to 400, it has the same configuration, operation and effect as the liquid crystal display device described in the first embodiment. Therefore, the same components are described with the same reference numerals.

  The liquid crystal display panel 100 and the frame 400 are configured in the same manner as in the first embodiment. As in the first embodiment, a first gap G1 is provided between the four sides of the display panel 100 and the frame 400.

  The driving side polarizing plate 300 is bonded to the entire surface of the overlapping region 100A and the external connection region 100B of the liquid crystal display panel 100. Thereby, the strength of the external connection region 100B configured only by the drive substrate 110 can be increased, and the display panel 100 can be more reliably protected from damage. In addition, a fixing part 300B similar to the fixing part 200B described in the first embodiment is provided in the extension part 300A of the driving side polarizing plate 300 for fixing to the frame 400.

  The counter-side polarizing plate 200 has extended portions 200 </ b> A that protrude from the counter substrate 120 on three sides except one side where the external connection region 100 </ b> B of the liquid crystal display panel 100 is provided. The protruding amount L2 of the extended portion 200A is smaller than the first gap G1, and a second gap that is smaller than the first gap G1 is provided between the extended portion 200A of the opposing-side polarizing plate 200 and the frame 400. G2 is provided (G1> G2 ≧ 0).

  This liquid crystal display device can be manufactured in the same manner as in the first embodiment except that the extended portion 300A of the driving side polarizing plate 300 is fixed to the frame 400.

  In the present embodiment, a case has been described in which the extension part 300A of the driving side polarizing plate 300 is provided on three sides excluding the side on which the external connection region 100B is provided, but the extension is also applied to the external connection region 100B. The portion 300A may be provided and fixed to the frame 400. In the case of such a support structure, it is possible to make the FPC 130 out of the hole while providing a hole in the frame 400 and providing the receiving side polarizing plate 300 receiving portion, as shown in FIG. Similarly to the case, the FPC 130 may be brought out from an FPC outlet portion (not shown) between the expansion portion 300A of the driving side polarizing plate 300 and the frame 400 without providing a hole or the like.

  Conversely, the driving-side polarizing plate 300 may be bonded only to the overlapping region 100A without covering the external connection region 100B of the liquid crystal display panel 100 due to space or the like.

  In this case, when the strength of the external connection region 100B becomes a problem, it is desirable to reinforce by extending the opposing substrate 200 to the external connection region 100B, as will be described later.

  For example, FIG. 9 shows the case where the counter-side polarizing plate 200 is not provided in the external connection region 100B. However, if the thickness of the FPC 130 is equal to or less than the thickness of the counter substrate 120, the driving-side polarizing plate 300 is externally connected. When the connection region 100B is not covered, the counter-side polarizing plate 200 may be extended to the external connection region 100B by attaching the counter-side polarizing plate 200 after mounting the FPC 130. As a result, it is possible to also serve as peeling protection between the FPC 130 and the driving substrate 110. Furthermore, if the ultraviolet curable resin 140 or the like is applied between the FPC 130 and the drive substrate 110 between the portion extending to the external connection region 100B of the opposite side polarizing plate 200, the drive of the external connection region 100B having the weakest strength is driven. It is possible to greatly improve the strength of the substrate 110 and the peel strength of the FPC. In addition, in this case, by extending the counter-side polarizing plate 200 to the external connection region 100B, it becomes easier to control the thickness due to the coating amount of the ultraviolet curable resin 140 than in the past. It is valid.

  When the thickness of the FPC 130 is the above-described thickness (the thickness of the counter substrate 120 or less), naturally, both the driving side polarizing plate 300 and the counter side polarizing plate 200 can be extended to the external connection region 100B. It is also possible to apply the ultraviolet curable resin 140. In this way, reinforcement of the external connection region 100B can be further ensured.

  While the present invention has been described with reference to the embodiment, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, the case has been described in which the extended portions 200A and 300A are provided on three sides except for one side where the external connection region 100B of the liquid crystal display panel 100 is provided. The extended portion of the polarizing plate attached to the substrate and the frame 400 may be provided on at least two parallel sides of the display panel 100, and the extended portion of the polarizing plate bonded to the lower (light guide plate 600 side) substrate is The display panel 100 may be provided on at least two intersecting sides.

  Furthermore, for example, the material and thickness of each layer described in the above embodiment are not limited, and other materials and thicknesses may be used.

  Furthermore, in the above-described embodiment, the configuration of the liquid crystal display device has been specifically described. However, it is not necessary to provide all the layers, and other layers may be further provided.
