Description

Technical Field

[0001] The present invention relates to a display device.

Background Art

[0002] As a display device, a liquid crystal display device having a liquid crystal panel for displaying an image and a backlight module disposed on the back side of the liquid crystal panel is known. The liquid crystal panel includes a display area and a non-display area around the display area. An image is displayed by selectively transmitting light irradiated from the backlight module to the back of the display area. A frame-shaped panel holder is disposed between the liquid crystal panel and the backlight module, and a bezel is disposed on the front side of the liquid crystal panel. The liquid crystal panel is held so that the non-display area is sandwiched between the panel holder and the bezel. The panel holder is formed of a material having a low reflectance so as not to unnecessarily reflect the light emitted from the backlight module and degrade the display quality.

[0003] An elastic body such as a cushion or silicone rubber is often disposed at the contact portion between the panel holder and the liquid crystal panel and at the contact portion between the bezel and the liquid crystal panel. This elastic body serves to relieve the stress applied to the liquid crystal panel and prevent dust from entering between the liquid crystal panel and the backlight module.

[0004] In recent years, in order to improve the design and installation properties, the narrow border of liquid crystal display devices has been progressing. Patent Document 1 discloses a liquid crystal display device in which a part of the shape of the panel holder is tapered in order to achieve both a narrow border and uniform display quality.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In the liquid crystal display device disclosed in Patent Document 1, the appearance of brightness at the edges of the light guide plate when the liquid crystal display device is viewed from an oblique angle is suppressed. However, due to the narrow bezel, when the panel holder is close to the display area of ​​the liquid crystal panel when viewed from the front, the panel holder, which has low reflectivity, absorbs light from the backlight module, causing the outer edge of the display area to become dark.

[0007] Furthermore, the narrower bezel reduces the non-display area, and the contact area between the elastic body and the liquid crystal panel also decreases, making it difficult to properly hold the liquid crystal panel while suppressing stress on it. If the force acting from the elastic body on the liquid crystal panel is too large, the display quality will deteriorate due to the stress on the liquid crystal panel; if the force acting from the elastic body on the liquid crystal panel is too small, the display quality will deteriorate due to the intrusion of dust.

[0008] This degradation in display quality also occurs in liquid crystal display devices and organic EL display devices disclosed in Patent Document 1.

[0009] The present invention aims to provide a display device that suppresses the deterioration of display quality caused by narrow bezels. [Means for solving the problem]

[0010] The first display device of the present invention comprises a display panel and a frame-shaped support surrounding the display panel. The panel holder comprises a panel holder, the panel holder having a first projection that protrudes inward from the frame shape for supporting the periphery of the display panel from the rear side, and the tip of the first projection has a higher light reflectivity than at least a portion of the other parts of the panel holder.

[0011] The second display device of the present invention comprises a substantially rectangular display panel, a back elastic body, and a frame-shaped panel holder that supports the periphery of the display panel from the back side via the back elastic body, wherein, when the display panel is supported by the panel holder, the flexibility of the back elastic body is higher in the second portion corresponding to the corners of the display panel than in the first portion not corresponding to the corners.

[0012] The third display device of the present invention comprises a display panel, a back elastic body, and a frame-shaped panel holder that supports the periphery of the display panel from the back side via the back elastic body, wherein the surface of the back elastic body that is on the central side of the display panel is inclined and rises from the back of the display panel so as to move from the display panel side toward the panel holder side. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a display device that suppresses the deterioration of display quality due to narrow bezels. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described in detail based on the accompanying drawings. In the following, an example in which the present invention is applied to a liquid crystal display device will be described, but the present invention is also applicable to other display devices such as an organic EL display device. Further, in the following, the configuration of a specific side (right side or lower side) among the upper side, lower side, left side, and right side of the display device will be described in detail, but the same configuration can be adopted for the other sides (left side or upper side).

[0016] <Embodiment 1> Embodiment 1 of the present invention will be described. FIG. 1 is an exploded perspective view of a liquid crystal display device 1 according to Embodiment Ⅰ, and FIG. 2 is a front view of the liquid crystal display device 1.

[0017] The liquid crystal display device 1 has an electrical circuit board for driving, internal components, and a rear cover (not shown) on the back side of the display module 20, which is a unit for displaying images. The display module 20 includes, in order from the front side, a bezel 3, a liquid crystal panel 2, a panel holder 30, an optical sheet group 11, and a backlight module 4.

[0018] The backlight module 4 has a light source substrate 5 with multiple light sources 9 mounted on it, and a reflective sheet 10 inside a case 8 located on the back side. The light sources 9 are not particularly limited, but for example, they are LEDs (Light Emitting Diodes). The reflective sheet 10 is for efficiently reflecting light from the light sources 9 to the optical sheet group 11, and the reflective sheet 10 is made of a material with high reflectivity or has a surface treatment applied. The case 8 is preferably made of a component formed by machining (such as press working) using a metal material, taking into consideration strength and heat dissipation of the light sources 5.

[0019] The bezel 3 is a frame that supports the periphery of the liquid crystal panel 2 from the front side via a front elastic body 50, which will be described later. The bezel 3 is often formed by machining (such as press working) using a metal material, but it may also be formed by resin molding.

[0020] The optical sheet group 11 is a sheet- or plate-shaped component for optically aligning the light from the backlight module 4 and irradiating it onto the liquid crystal panel 2. The optical sheet group 11 consists of a diffuser plate for making the light intensity uniform in the planar direction, and a prism sheet for controlling the direction of light emission. Polycarbonate or polyethylene terephthalate are used as materials for the optical sheet group 11.

[0021] Figure 3 is a cross-sectional view of the liquid crystal display device 1, showing the AA cross-section in Figure 2. Figure 4 is a cross-sectional view of the panel holder 30, extracted from Figure 3.

[0022] The liquid crystal panel 2 is a roughly rectangular display panel that displays images, and has a non-display area 2B surrounding the display area 2A. The display area 2A is the area that displays images by selectively transmitting light from the backlight module 4 located on the back side to the front side, and the bezel 3 and panel holder 30 have openings that do not obstruct the light of the display area 2A. The non-display area 2B is the area sandwiched between a front elastic body 50 attached to the bezel 3 and a back elastic body 40 attached to the panel holder 30. The liquid crystal panel 2 is held in place by the non-display area 2B being sandwiched between the front elastic body 50 and the back elastic body 40.

[0023] The panel holder 30 is a frame-shaped member formed by injection molding using a resin material such as polycarbonate, and is fixed to the case 8 with the optical sheet group 11 in between. The panel holder 30 is made of a low-reflectivity color such as black so as not to unnecessarily reflect strong light from the optical sheet group 11 or stray light emitted or reflected from the edges of the liquid crystal panel 2 back to the liquid crystal panel 2. The panel holder 30 supports the periphery of the liquid crystal panel 2. Specifically, the panel holder 30 supports the periphery of the liquid crystal panel 2 from the back side via the back elastic body 40.

[0024] The panel holder 30 includes a base portion 130 parallel to the liquid crystal panel 2 and the optical sheet group 11, and two vertical wall portions (liquid crystal panel side vertical wall portion 131 and optical sheet side vertical wall portion 132) perpendicular to the base portion 130. The liquid crystal panel side vertical wall portion 131 extends toward the liquid crystal panel 2 side (front side), and its front end contacts the inner surface of the bezel 3. The optical sheet side vertical wall portion 132 is an optical sheet It extends toward the side of the 11 group (rear side), and the end on the rear side contacts the case 8.

[0025] The base portion 130 is a part that supports the periphery of the liquid crystal panel 2 from the rear side (via the back elastic body 40), and is a protruding portion that projects inward toward the frame-shaped outer shape of the panel holder 30. The base portion 130 has a liquid crystal panel side base surface 133 on the liquid crystal panel 2 side that is parallel to and faces the liquid crystal panel 2. The base portion 130 also has an optical sheet side base surface 134 on the optical sheet group 11 side that is parallel to and faces the optical sheet group 11. Furthermore, the base portion 130 has an inner circumferential surface 135 and an inner circumferential inclined surface 136 as surfaces that form an opening for allowing light from the backlight module 4 to pass through to the liquid crystal panel 2 side. The inner circumferential surface 135 is perpendicular to the liquid crystal panel 2 and is located on the outer periphery (outside) of the display area 2A when viewed from the front. The inner circumferential inclined surface 136 is a chamfered inclined surface that connects the inner circumferential surface 135 and the optical sheet side base surface 134, and is inclined to open towards the optical sheet group 11 so as not to obstruct the light emitted from the optical sheet group 11 as much as possible.

[0026] A rear elastic body 40 for holding the LCD panel 2 from the rear is positioned on the LCD panel side base surface 133 by adhesive using double-sided tape or the like. The rear elastic body 40 holds the LCD panel 2 by sandwiching it from the front and rear together with a front elastic body 50 provided on the inner circumference of the bezel 3.

[0027] A reflective sheet 110 (light-reflecting sheet) is placed on the inner circumferential surface 135 to reflect light emitted from the optical sheet group 11 towards the liquid crystal panel 2. The reflective sheet 110 is attached to the inner circumferential surface 135 (the tip of the base portion 130) by, for example, double-sided tape or adhesive, and is positioned on the outer periphery of the display area 2A of the liquid crystal panel 2 when viewed from the front. The material of the reflective sheet 110 is, for example, foamed polyethylene terephthalate. When the reflective sheet 110 is made of foamed polyethylene terephthalate, the reflectivity of the reflective sheet 110 is approximately 95% to 98%.

[0028] In this way, by arranging the reflective sheet 110 on the inner surface 135, it becomes possible to reflect the light L100 irradiated from the optical sheet group 11 onto the inner surface 135 of the panel holder 30 towards the liquid crystal panel 2. As a result, even when the inner surface 135 of the panel holder 30 is close to the display area 2A when viewed from the front due to the narrow bezel, a decrease in brightness at the outer edge of the display area 2A can be suppressed. In addition, since the panel holder 30 is formed of a color with low reflectivity such as black, stray light reflected from the liquid crystal panel side base surface 133 and the optical sheet side base surface 134 is less likely to occur, and a decrease in display quality due to stray light can also be suppressed.

[0029] Figures 5(a) to 5(c) are vertical cross-sectional views showing modified examples of the panel holder according to Embodiment 1 and the reflective sheet of the panel holder, corresponding to cross-section AA in Figure 2. In the above example, the reflective sheet 110 was attached only to the inner circumferential surface 135, but as shown in the reflective sheet 110a of Figure 5(a), the reflective sheet may also be attached to the inner inclined surface 136. As shown in Figure 5(b), a panel holder 30c without an inner inclined surface 136 may be used, and the reflective sheet 110b may be attached to the entire inner circumferential surface 135c that is in contact with the liquid crystal panel side base surface 133 and the optical sheet side base surface 134. Alternatively, as shown in the reflective sheet 110c of Figure 5(c), the reflective sheet may be attached so as to cover a part of the liquid crystal panel side base surface 133 and a part of the optical sheet side base surface 134. In this case, the back elastic body 40 may be attached on top of the reflective sheet 110c. Or, the reflective sheet 110c may also perform the role of the back elastic body 40. As a result, the reflective sheet 110c is pressed against the panel holder 30 by the liquid crystal panel 2 and the optical sheet group 11, thereby preventing the reflective sheet 110c from peeling off the panel holder 30.

[0030] Figures 6(a) to 6(c) are longitudinal cross-sectional views showing modified examples of the panel holder according to Embodiment 1. This corresponds to the AA cross-section in Figure 2. In the panel holder 30 described above, the molded color was a low-reflectivity color such as black, but the panel holder may also be formed by two-color molding, such as the panel holder 30d in Figure 6(a), where the molded color is high-reflectivity white only near the inner circumferential surface 135d. Since the reflectivity of white resin material is often 70% or more, for example, around 70% to 85%, the effect of reflecting light from the backlight module 4 to the liquid crystal panel 2 can be obtained even without placing a reflective sheet 110 on the inner circumferential surface 135d. Alternatively, the reflectivity of the inner circumferential surface 135e may be increased by white painting, as in the panel holder 30e in Figure 6(b). Or, as in the panel holder 30f in Figure 6(f), the entire molded color may be high-reflectivity white, and the surfaces other than the inner circumferential surface 135f may be painted black.

[0031] As described above, according to this embodiment, the reflectivity of the inner surface of the panel holder (the tip of the base portion) is increased to a higher reflectivity than other parts of the panel holder. As a result, even when the inner surface of the panel holder is close to the display area of ​​the liquid crystal panel when viewed from the front due to the narrow bezel, a decrease in brightness at the outer edge of the display area can be suppressed.

[0032] <Embodiment 2> Embodiment 2 of the present invention will now be described. Descriptions of configurations similar to those in other embodiments will be omitted as appropriate, and configurations different from those in other embodiments will be described in detail.

[0033] Figure 7(a) is a front view showing the arrangement of the back elastic body of a liquid crystal display device according to Embodiment 2. As described in Embodiment 1, the liquid crystal panel of the liquid crystal display device is held by being sandwiched between a front elastic body attached to the bezel and a back elastic body attached to the panel holder. The panel holder 230 in Figure 7(a) has a frame shape with an opening 230h (an opening through which light from the backlight module passes) in the center when viewed from the front. The back elastic bodies 240 and 241 are arranged along the edge of the opening 230h. The liquid crystal panel is placed on the back elastic bodies 240 and 241, and the position of the liquid crystal panel is determined by bringing the end faces of the liquid crystal panel into contact with the protrusions 237 and 238 of the panel holder 230. The back elastic body 240 is arranged parallel to the vertical direction of the liquid crystal display device, and the back elastic body 241 is arranged parallel to the horizontal direction of the liquid crystal display device. The back elastic bodies 240 and 241 are both rectangular-shaped cushions made primarily of urethane or rubber.

[0034] Figure 7(b) is a cross-sectional view of the back elastic body of the liquid crystal display device according to Embodiment 2, showing the BB cross-section in Figure 7(a). The panel holder 230 has a liquid crystal panel side vertical wall portion 231 erected on the liquid crystal panel side (front side) and a base portion facing the liquid crystal panel. The base portion has a liquid crystal panel side base surface 233 and a protruding portion 233t on the liquid crystal panel side. The liquid crystal panel side base surface 233 and the protruding portion 233t are continuous, and the protruding portion 233t is closer to the liquid crystal panel than the liquid crystal panel side base surface 233. When the back elastic body 241 is attached to the liquid crystal panel side base surface 233 and the protruding portion 233t, the back elastic body 241 follows the protruding portion 233t and protrudes in the direction of the liquid crystal panel in the portion where the protruding portion 233t is located (region R1). In Figure 7(b), region R1 is the region corresponding to the protruding portion 233t, and region R2 is the other region. Although not shown in the diagram, the back elastic body 240 has a similar shape to the back elastic body 241.

[0035] Figure 7(c) is a cross-sectional view of the back elastic body of the liquid crystal display device according to Embodiment 2 with the liquid crystal panel placed on it. As mentioned above, the back elastic body 241 is a flexible material such as a cushion. Therefore, when the liquid crystal panel 2 is placed on the back elastic body 241, the back elastic body 241 is compressed. When the liquid crystal panel 2 is placed, the protrusion 233t of the panel holder 230 comes close to the liquid crystal panel 2, and the protrusion 233t bears the load of the liquid crystal panel 2. Therefore, the back elastic body 241 is compressed the most in region R1. On the other hand, in region R2, the compression rate of the back elastic body 241 is low, so the liquid crystal panel 2 adapts to the flexibility of the back elastic body 241. It is possible to move along with the back elastic body. In other words, in region R2, even if warping occurs in the liquid crystal panel 2, the back elastic body 241 follows the deformation of the liquid crystal panel 2, thereby suppressing stress generation in the liquid crystal panel 2 and preventing a decrease in display quality. In addition, by the back elastic body 241 deforming in accordance with (in close contact with) the liquid crystal panel 2, the intrusion of dust can be suppressed. Generally, liquid crystal panels are prone to warping due to temperature and humidity, and warping is particularly noticeable at the four corners. Therefore, in the state shown in Figure 7(c), it is preferable that the compression ratio (high flexibility) of the back elastic bodies 240 and 241 is lower in region R2, which corresponds to the corners of the liquid crystal panel 2, than in the region that does not correspond to the corners of the liquid crystal panel 2, where the back elastic bodies 240 and 241 intersect. If we define L1 as the length of the longer side of the liquid crystal panel 2, and L2 as the length of the portion sandwiched between the two end regions R2, i.e., the portion including the two end regions R1, then considering the curvature of the liquid crystal panel as described above, it is preferable that length L2 be 50% or more and 80% or less of length L1. Length L1 can also be considered as the length of one side of the liquid crystal panel 2, and length L2 can also be considered as the length of the portion of that side that does not correspond to the corner of the liquid crystal panel 2.

[0036] Figure 8(a) is a front view showing the arrangement of Modified Example 1 of the back elastic body of the liquid crystal display device according to Embodiment 2. Figure 8(b) is a cross-sectional view of Modified Example 1 of the back elastic body of the liquid crystal display device according to Embodiment 2. Figure 8(c) is a cross-sectional view of Modified Example 1 of the back elastic body of the liquid crystal display device according to Embodiment 2 with the liquid crystal panel placed on it.

[0037] In Figure 7(a), the back elastic bodies 240 and 241 were each composed of a single component. In Figure 8(a), the first back elastic body 240a and the second back elastic body 241a are arranged alternately as vertical back elastic bodies, with the short-side end face of the first back elastic body 240a in contact with the short-side end face of the second back elastic body 241a. Similarly, the first back elastic body 242a and the second back elastic body 243a are arranged alternately as horizontal back elastic bodies. The first back elastic bodies 240a and 242a are made of a material such as silicone rubber. The second back elastic bodies 241a and 243a are cushions made of foam such as urethane. In other words, the first back elastic bodies 240a and 242a are harder and less deformable than the second back elastic bodies 241a and 243a. Conversely, this means that the second back elastic bodies 241a and 243a have lower hardness and are more easily deformable than the first back elastic bodies 240a and 242a. In Figures 8(a) and 8(b), the region where the first back elastic body is located is shown as region R1, and the region where the second back elastic body is located is shown as region R2. In Figure 8(b), the thickness of each member (thickness in the direction perpendicular to the back of the liquid crystal panel 2) is shown, and the second back elastic body 243a in region R2 is thicker than the first back elastic body 242a in region R1. As a result, when the liquid crystal panel 2 is placed on it, as shown in Figure 8(c), the second back elastic body 243a is mainly compressed. As mentioned above, since the second back elastic body 243a is a cushion, even if the second back elastic body 243a is compressed, almost no stress is generated in the liquid crystal panel 2, and there is no decrease in display quality. The first back elastic body 242a is hardly compressed even when the liquid crystal panel 2 is placed on it (its thickness is almost maintained). Also, similar to the example in Figure 7(c), in region R2, even if warping occurs in the liquid crystal panel 2, the second back elastic body 243a follows the deformation of the liquid crystal panel 2, thereby suppressing stress generation in the liquid crystal panel 2 and preventing a decrease in display quality. In addition, the back elastic body 241 deforms in accordance with the liquid crystal panel 2 (while in close contact), which helps to suppress the intrusion of dust.

[0038] Figure 9 is a front view showing the arrangement of a modified example 2 of the back elastic body of a liquid crystal display device according to Embodiment 2. Similar to the modified example 1 described above, the first back elastic bodies 240b, 242b and the second back elastic bodies 241b, 243b are arranged along the edge of the opening 230h of the panel holder 230 (or the edge of the liquid crystal panel 2). The first back elastic bodies 240b, 242b are made of a material such as silicone rubber, and the second back elastic bodies 241b, 243b are made of a cushioning material such as urethane, and the first back elastic bodies 240b, 242b have higher hardness than the second back elastic bodies 241b, 243b. The first back elastic body 242b and the second back elastic body 2 are horizontal back elastic bodies. Although 43b is in contact with each other at the end faces on their respective short sides, variations in assembly can cause slight gaps in the contact area. Dust can enter through these gaps in the direction of the opening 230h, potentially causing dust to adhere to the back surface of the LCD panel 2 and the backlight module, thus degrading the display quality. Therefore, the third back elastic body 244 is positioned to close the aforementioned gaps. Specifically, the third back elastic body 244 is provided along the connection points of the first back elastic body 240b and the second back elastic body 241b, and along the connection points of the first back elastic body 242b and the second back elastic body 243b. The third back elastic body 244 is made of a cushioning material such as urethane, similar to the second back elastic bodies 241b and 243b, and its thickness is about the same as the second back elastic bodies 241b and 243b, but thicker than the first back elastic bodies 240b and 242b. The third back elastic body is also positioned similarly as a vertical back elastic body. By doing so, the intrusion of dust can be further suppressed, and the deterioration of the display quality can be further suppressed.

[0039] As described above, according to this embodiment, by making the back elastic body flexible at the corners of the liquid crystal panel, even when the area in which the back elastic body can be placed is reduced due to the narrowing of the bezel, it is possible to suppress a decrease in display quality and the intrusion of dust.

[0040] <Embodiment 3> Embodiment 3 of the present invention will now be described. Descriptions of configurations similar to those in other embodiments will be omitted as appropriate, and configurations different from those in other embodiments will be described in detail.

[0041] Figures 10(a) and 10(b) are cross-sectional views of a liquid crystal display device according to Embodiment 3. As shown in Figure 10(a), the liquid crystal panel 2 of the liquid crystal display device according to Embodiment 3 is held from the front and rear directions by a front elastic body 350 provided on the bezel 3 and a back elastic body 340 provided on the panel holder 330. The panel holder 330 has a frame shape with an opening in the center (an opening through which light from the backlight module passes) when viewed from the front. The front elastic body 350 and the back elastic body 340 are arranged in the non-display area 2B of the liquid crystal panel 2. The back elastic body 340 is arranged along the four sides of the opening of the panel holder 330 when viewed from the front, realizing a dustproof structure that prevents (suppresses) foreign matter from entering the back side of the liquid crystal panel 2 and the inside of the backlight module. The base surface 333 on the liquid crystal panel side of the panel holder 330 to which the back elastic body 340 is bonded is inclined. Therefore, the central side of the back elastic body 340 of the liquid crystal display device is inclined at an angle θ toward the center of the liquid crystal panel 2 from the backlight module toward the liquid crystal panel 2. This can also be seen as the central side of the liquid crystal panel 2 rising from the back of the liquid crystal panel 2 at an angle (90 degrees - θ) toward the panel holder 330. These inclination angles are preferably 15 degrees or more and 75 degrees or less.

[0042] When using a liquid crystal panel 2 with a narrow bezel, the back elastic body 340 needs to be positioned near the boundary between the display area 2A and the non-display area 2B of the liquid crystal panel 2 to obtain the necessary dustproof performance. Even in this case, by tilting the back elastic body 340 at an inclination angle θ, the amount of back elastic body close to the display area 2A is reduced, making it less likely for the illumination light from the backlight module to be blocked by the back elastic body at the periphery of the display area 2A. Consequently, a decrease in brightness at the periphery of the display area 2A can be suppressed. Furthermore, by tilting the back elastic body 340 at an inclination angle θ, the contact area between the liquid crystal panel and the back elastic body is increased, allowing the liquid crystal panel to be held securely.

[0043] As described above, according to this embodiment, by tilting and contacting the back elastic body with the non-display area of ​​the liquid crystal panel, even with a narrow bezel, the reduction in brightness at the periphery of the display area can be suppressed, and dust can be prevented by the back elastic body. Furthermore, the liquid crystal panel can be held securely. As shown in Figure 10(b), the back elastic body 340 may be extended to the outside of the liquid crystal panel 2 and brought into contact with the front elastic body 350. In this way, the front elastic body 350 and the back elastic body 340 This allows for dust protection even during operation, further suppressing the intrusion of foreign matter into the back side of the LCD panel 2 (improved dustproof performance).

[0044] <Embodiment 4> Embodiment 4 of the present invention will now be described. Descriptions of configurations similar to those in other embodiments will be omitted as appropriate, and configurations different from those in other embodiments will be described in detail.

[0045] The back elastic body is compressed and deformed by the panel holder and liquid crystal panel, thereby achieving dustproof and panel holding functions. However, if the compressed and deformed portion protrudes from the opening of the panel holder into the display area, a phenomenon may occur where the back elastic body appears like a shadow (a decrease in display quality, such as a reduction in brightness at the edges of the display area) depending on the viewing angle when viewing the image. As the contact area between the back elastic body and the liquid crystal panel becomes smaller due to the narrow bezel, this decrease in display quality is more likely to occur. In this embodiment, the shape of the back elastic body and the panel holder is changed to suppress this decrease in display quality.

[0046] Figure 11 is a cross-sectional view of a liquid crystal display device according to Embodiment 4. A back elastic body 442 is positioned between the liquid crystal panel 2 and the panel holder 430. The back elastic body 442 is a cushion that extends in the longitudinal direction when viewed from the front. As mentioned above in Embodiment 1, the back elastic body 442 is attached to the base surface 433 on the liquid crystal panel side of the panel holder 430 with double-sided tape or adhesive. In this embodiment, a groove 431 (recess) is provided in a part of the base surface 433 on the liquid crystal panel side of the panel holder 430. The depth of the groove 431 is preferably 0.5 mm or more. The back elastic body 442 is provided so as to straddle the end of the groove 431 (the end closer to the center of the liquid crystal panel 2). The back elastic body 442 is not attached in the part of the groove 431, and a gap is provided between the back elastic body 442 and the groove 431. When the liquid crystal panel 2 is assembled, the back elastic body 442 is compressed and deformed, and a part of it fits into the groove 431. This prevents the back elastic body 442 from protruding into the display area. The back elastic body 442 may also be adhered to the bottom surface of the groove 431, which causes the back elastic body 442 to tilt into the groove 431, further preventing it from protruding into the display area.

[0047] Figures 12(a) to 12(e) are cross-sectional views showing modified examples of the liquid crystal display device according to Embodiment 4. The same effects as in Figure 11 can be obtained with the shapes of the panel holder and back elastic body in Figures 12(a) to 12(e).

[0048] In Figure 12(a), the panel holder 430a has a slanted portion 432a on the side furthest from the opening, relative to the surface to which the back elastic body 442a is bonded. The back elastic body 442a is not bonded to the slanted portion 432a, and there is a gap between the back elastic body 442a and the slanted portion 432a. When the liquid crystal panel 2 is assembled, the back elastic body 442 is compressed and deformed, and a part of it enters the space (groove) formed by the slanted portion 432a. This prevents the back elastic body 442a from protruding into the display area.

[0049] In Figure 12(b), a slanted portion 432b is provided such that one end forms an opening in the panel holder 430b (one end contacts the opening), and the back elastic body 442b is bonded to the slanted portion 432b. The back elastic body 442b does not contact the liquid crystal panel 2 parallel to it, but the compressed and deformed portion moves to the side opposite to the opening of the panel holder 430b.

[0050] In Figure 12(c), the cross-sectional shape of the back elastic body 442c is not rectangular, but rather has a shape in which one of the four corners of a rectangle is missing, on the side of the panel holder 430c and the side furthest from the opening. The compressed and deformed portion of the back elastic body 442c moves to the part where the corner is missing. Note that the corner on the liquid crystal panel 2 side may also be missing. In the state before the liquid crystal panel 2 is assembled, the thickness of the back elastic body is on the side furthest from the center of the liquid crystal panel 2, and at the center It just needs to be thinner than the side that's closer.

[0051] In Figure 12(d), the cross-sectional shape of the back elastic body 442d is not rectangular. The back elastic body 442d has a groove (notch) on the side furthest from the opening, which is a surface that is approximately perpendicular to the adhesive surface of the panel holder 430d (the surface that rises from the adhesive surface). The compressed and deformed portion of the back elastic body 442d moves to the groove.

[0052] In Figure 12(e), the cross-sectional shape of the back elastic body 442e is not rectangular, and the surface of the back elastic body 442e that contacts the liquid crystal panel 2 has a convex shape. Before the liquid crystal panel 2 is assembled, the thickness of the back elastic body 442e gradually increases and decreases in the direction away from the center of the liquid crystal panel 2. As in other examples, the back elastic body 442e is bonded to the panel holder 430e. The compressed and deformed portion of the back elastic body 442e moves into the surrounding gap formed by the convex shape.

[0053] Figure 13 is a cross-sectional view showing another modification of the liquid crystal display device according to Embodiment 4. The example in Figure 13 is based on the configuration of Figure 10 (Embodiment 3). As also described in Embodiment 3, the base surface 443 on the liquid crystal panel side, which is the adhesive surface for the back elastic body 445 of the backlight, is inclined, and the back elastic body 445 is inclined toward the center of the liquid crystal panel 2 from the backlight module toward the liquid crystal panel 2. In the example in Figure 13, the base surface 443 on the liquid crystal panel side is made smaller than the surface of the back elastic body 445 that is adhered to the base surface 443 on the liquid crystal panel side. The back elastic body 445 is then adhered to the base surface 443 on the liquid crystal panel side such that the side opposite to the opening of the panel holder 435 floats (is not adhered to the panel holder 435). By doing this, the compressed and deformed portion of the back elastic body 445 moves toward the side opposite to the opening of the panel holder 435, and it is possible to suppress the back elastic body 445 from protruding into the display area.

[0054] As described above, according to this embodiment, by changing the shape of the back elastic body and the panel holder, when the liquid crystal panel is assembled, the back elastic body compresses and deforms in a direction away from the center of the liquid crystal panel. As a result, even if the contact area between the back elastic body and the liquid crystal panel becomes smaller due to the narrow bezel, a decrease in brightness at the periphery of the display area can be suppressed.

[0055] <Embodiment 5> Embodiment 5 of the present invention will now be described. Descriptions of configurations similar to those in other embodiments will be omitted as appropriate, and configurations different from those in other embodiments will be described in detail.

[0056] Figures 14(a) and 14(b) show the arrangement of the back elastic body of the liquid crystal display device according to Embodiment 5. The upper half is omitted because it is vertically symmetrical.

[0057] As shown in Figure 3, the liquid crystal panel is held in place by a front elastic body attached to the bezel and a back elastic body attached to the panel holder. In Figure 14(a), the back elastic body for holding the liquid crystal panel is attached to the panel holder 530 without any gaps around the opening. The first back elastic body 540 is made of a material such as silicone rubber. The second back elastic body 541 is a cushion made of foam such as urethane. That is, the first back elastic body 540 is harder and less prone to deformation than the second back elastic body 541. The liquid crystal panel is placed on the first back elastic body 540 and the second back elastic body 541, and the position of the liquid crystal panel is determined by bringing the end face of the liquid crystal panel into contact with the protrusions of the panel holder 530. The other detailed configurations are the same as in Embodiment 2.

[0058] The first back elastic body 540 and the second back elastic body 541 are attached along the opening of the panel holder 530. In order to suppress the intrusion of dust and other debris, the second back elastic body 541 is 1 It is preferable that the second back elastic body be a continuous elastic body and be positioned so as to wrap around the first back elastic body 540 from the outside when viewed from the front. Furthermore, the second back elastic body 541 must be attached so as not to be separated from the first back elastic body 540.

[0059] In order to attach the second back elastic body 541 to the first back elastic body 540 without separating them, the second back elastic body 541 must be crank-shaped (a shape that curves sharply in a continuous and different direction) so as not to overlap with the first back elastic body 540. If the first bending position and the second bending position are close together, the repulsive force of the second back elastic body 541 will deform in a direction away from the first back elastic body 540, creating a gap. In this embodiment, a rib 550 (Figure 14(a)) is provided on the panel holder 530 to guide the crank-shaped second back elastic body 541 so as not to create this gap. The height of the rib 550 is preferably about half the thickness of the second back elastic body 541. The rib 550 is installed at a horizontal distance 3B away from the end face of the first back elastic body 540, which is less than or equal to the width 3A of the second back elastic body 541. Furthermore, marking lines or the like may be placed on the mold of the panel holder 530 to indicate the attachment position of the first back elastic body 540 in the panel holder 530. In the example shown in Figure 14(a), when the second back elastic body 541 is bent and positioned, the outside of the second back elastic body 541 is pressed down by the rib 550, suppressing deformation of the second back elastic body 541. As a result, it becomes possible to attach the second back elastic body 541 to the first back elastic body 540 without separating them.

[0060] Figure 14(b) shows a modified example in which a third back elastic body 551 is placed instead of the rib 550 described above. The third back elastic body 551 is made of the same material as the first back elastic body 540. The placement and height of the third back elastic body 551 are the same as those of the rib 550. Marking lines or the like may be placed on the mold of the panel holder 530 to indicate the attachment positions of the first back elastic body 540 and the third back elastic body 551 in the panel holder 530. In the example of Figure 14(b), when the second back elastic body 541 is bent and placed, the outside of the second back elastic body 541 is pressed down by the third back elastic body 551, suppressing the deformation of the second back elastic body 541. Therefore, it is possible to attach the second back elastic body 541 to the first back elastic body 540 without separating them.

[0061] Figure 15 is a diagram showing the arrangement of the back elastic body of the liquid crystal display device according to Embodiment 5. The upper half is omitted because it is vertically symmetrical. Figure 15 is a modified example in which a dowel 560 is placed instead of the rib 550 in Figure 14(a) or the third back elastic body 551 in Figure 14(b). A dowel 560 with a diameter of approximately 3 mm is placed on the panel holder 530. The placement location and height of the dowel 560 are the same as those of the rib 550. If a cylindrical dowel is used as the dowel 560, the contact area between the dowel 560 and the second back elastic body 541 is limited, improving ease of assembly.

[0062] Figure 16 is a diagram showing the arrangement of the back elastic body of the liquid crystal display device according to Embodiment 5. The upper half is omitted because it is vertically symmetrical. Figure 16 is a diagram showing a modified example in which the shape of the first back elastic body differs from that of Figures 14(a), 14(b), and 15. In Figure 16, protrusions such as ribs 550, a third back elastic body 551, and dowels 560, which suppress the separation of the first back elastic body and the second back elastic body, are not arranged on the panel holder 530. In Figure 16, the first back elastic body 545 is attached to the panel holder 530. The end face of the first back elastic body 545 is a surface cut at an angle of about 30 degrees with respect to the end face of the opening of the panel holder 530. This angle is preferably less than 45 degrees, but may be greater than 30 degrees. By attaching the second back elastic body 541 along the end face of the first back elastic body 545 which is cut at an angle of about 30 degrees, the second back elastic body 541 can be attached without separating from the first back elastic body 540.

[0063] As described above, according to this embodiment, even with a narrow bezel, it is possible to suppress the occurrence of gaps between multiple back elastic bodies and gaps between the liquid crystal panel and the back elastic body, preventing dust intrusion and backlighting. This can suppress light leakage from the tomodule.

[0064] <Embodiment 6> Embodiment 6 of the present invention will now be described. Descriptions of configurations similar to those in other embodiments will be omitted as appropriate, and configurations different from those in other embodiments will be described in detail.

[0065] Figure 17 is a cross-sectional view of the liquid crystal display device according to Embodiment 6, and Figures 18(a) and 18(b) are exploded cross-sectional views of the liquid crystal display device according to Embodiment 6, both corresponding to cross-section AA in Figure 2.

[0066] In Figure 17, similar to Figure 3, a rear elastic body 40 for holding the liquid crystal panel 2 from the rear is attached to the panel holder 630 by double-sided tape or the like. The liquid crystal panel 2 is also held between the front elastic body 650, which is located on the inner circumference of the bezel 3, and the aforementioned rear elastic body 40. A protrusion 637 is located on a part of the inner circumference of the panel holder 630. The protrusion 637 is formed to restrict the position of the liquid crystal panel 2, similar to the protrusion 238 in Embodiment 2, and is located close to the outer circumference of the liquid crystal panel 2.

[0067] In the case of a liquid crystal panel 2 with a small non-display area 2B, if the panel holder is in contact with the surface of the bezel where the front elastic body is located, as shown in Figure 3, the front elastic body 650 may be deformed by being pressed against the protrusion 637 of the panel holder 630. When the front elastic body 650 is deformed by being pressed against the protrusion 637 of the panel holder 630, stress is generated in the liquid crystal panel, which may reduce the display quality.

[0068] Therefore, in this embodiment, as shown in Figure 17, the panel holder 630 is not brought into contact with the surface of the bezel 3 facing the liquid crystal panel 2, and a space is provided between the bezel 3 and the panel holder 630, with the front elastic body 650 placed in this space. By doing so, it is possible to suppress unnecessary deformation of the front elastic body 650 by being pressed against the protrusions 637 of the panel holder 630, and consequently, to suppress a decrease in display quality.

[0069] As shown in Figure 18(a), the front elastic body 650 may be pre-bonded to the bezel 3 (the surface of the bezel 3 facing the liquid crystal panel 2), or the bezel 3 with the front elastic body 650 attached may be mounted to the backlight module. Alternatively, as shown in Figure 18(b), the front elastic body 650 may be positioned to straddle the liquid crystal panel 2 and the protrusion 637, and the bezel 3 may be mounted on top of it. In this case, the front elastic body 650 is bonded to the surface of at least one of the liquid crystal panel 2 and the panel holder 630 that faces the bezel 3.

[0070] As described above, according to this embodiment, by providing a space between the bezel and the panel holder, even with a narrow bezel, unnecessary deformation of the front elastic body can be suppressed, thereby suppressing a decrease in display quality.

[0071] <Embodiment 7> Embodiment 7 of the present invention will now be described. Descriptions of configurations similar to those in other embodiments will be omitted as appropriate, and configurations different from those in other embodiments will be described in detail.

[0072] The front elastic body is compressed and deformed by the panel holder and the liquid crystal panel, but because the narrow bezel reduces the area that holds the liquid crystal panel, the front elastic body is more likely to interfere with the support member placed on the underside of the liquid crystal panel. When such interference occurs, excessive stress is generated in the liquid crystal panel, and the display quality deteriorates. In this embodiment, the front elastic body, panel holder, and support member are modified to suppress the aforementioned interference. In this embodiment, an example is described in which the support member that supports the end face (lower end) of the liquid crystal panel is placed on the underside of the liquid crystal panel, but the upper and right sides of the liquid crystal panel are also described. A similar configuration can be adopted on the side and the left side.

[0073] Figure 19(a) is a cross-sectional view of a liquid crystal display device according to Embodiment 7. In Figure 19(a), similar to Figure 3, a back elastic body 40 for holding the liquid crystal panel 2 from the back is attached to the panel holder 730a by double-sided tape or the like. The liquid crystal panel 2 is sandwiched between a front elastic body 750 arranged on the inner circumference of the bezel 3 and the aforementioned back elastic body 40. A support member 777a is positioned between the lower surface of the liquid crystal panel 2 and the panel holder 730a. The material and shape of the support member 777a are determined so as to suppress stress concentration in the liquid crystal panel 2 even if warping occurs in response to external forces or changes in temperature and humidity. A sliding material is often used for the support member 777a. The support member 777a is often attached to the panel holder 730a with double-sided tape.

[0074] Normally, the support member is positioned perpendicular to the liquid crystal panel (parallel to the bottom surface of the liquid crystal panel) and positioned across the entire bottom surface of the liquid crystal panel. However, this arrangement can cause interference between the compressed and deformed front elastic body and the support member. Therefore, in Figure 19(a), a slope is formed on the panel holder 730a on the surface facing the bottom surface of the liquid crystal panel 2, extending away from the bottom surface of the liquid crystal panel 2, as the portion on the front side from approximately the center in the thickness direction of the liquid crystal panel 2 (panel centerline 7c). On the front side from the panel centerline 7c, the support member 777a follows the aforementioned slope and is positioned away from the liquid crystal panel 2. This suppresses the aforementioned interference. On the rear side from the panel centerline 7c, the support member 777a is positioned perpendicular to the liquid crystal panel 2. It is preferable that the vertical distance 7A from the bottom surface of the liquid crystal panel 2 to the tip of the support member 777a (front end) is longer than the vertical distance 7B from the bottom surface of the liquid crystal panel 2 to the lower end (outer end in front view) of the front elastic body 750. In other words, it is preferable that the vertical distance 7B is shorter than the vertical distance 7A.

[0075] Figure 19(b) shows a modified example in which the shape of the panel holder is changed from that of Figure 19(a). In Figure 19(b), a step is provided on the surface of the panel holder 730b that faces the bottom surface of the liquid crystal panel 2. The step is located at the position of the panel centerline 7c. Due to this step, the portion of the panel holder 730b facing the bottom surface of the liquid crystal panel 2 that is on the front side of the liquid crystal panel 2 from the panel centerline 7c is further from the bottom surface of the liquid crystal panel 2 than the portion that is on the back side of the liquid crystal panel 2 from the panel centerline 7c. On the front side of the liquid crystal panel 2 from the panel centerline 7c, the support member 777b bends so as to enter the space formed by the aforementioned step and moves away from the liquid crystal panel 2. This suppresses interference between the compressed front elastic body 750 and the support member 777b. On the back side of the panel centerline 7c, the support member 777a is positioned perpendicular to the liquid crystal panel 2. Furthermore, the support member 777b only needs to be flexible, and the thickness of the support member 777b may be large, or a rigid material may be used for the support member 777b. Since the support member 777b is not bonded to the panel holder 730b in front of the liquid crystal panel 2 from the panel centerline 7c, the bonding area between the support member and the panel holder can be reduced. For example, if the entire lower surface of the support member 777a is bonded to the panel holder 730 in Figure 19(a), the bonding area in Figure 19(b) can be reduced to approximately half of that in Figure 19(a).

[0076] Figure 20(a) is a cross-sectional view showing another modified example of the liquid crystal display device according to Embodiment 7. Unlike Figures 19(a) and 19(b), Figure 20(a) suppresses interference between the front elastic body and the support member by providing a shape in the bezel into which the front elastic body fits. In Figure 20(a), the support member 770 is attached to the panel holder 735 and is positioned perpendicular to the liquid crystal panel 2 (parallel to the lower surface of the liquid crystal panel 2) and is arranged across the entire lower surface of the liquid crystal panel 2. The front elastic body 750 is attached to the bezel 703a with double-sided tape or the like. A groove 760 (recess) is provided in the part of the bezel 703a that is close to the support member 770 (the surface facing the liquid crystal panel 2), and the front elastic body 750 is positioned so as not to interfere with the support member 770. It can be inserted into 60. Various materials such as metal and resin can be used for the bezel 703a. If the bezel 703a is manufactured (molded) from aluminum die casting or resin, the thickness of the part of the bezel 703a that contacts the front elastic body 750 can be easily increased, and the groove 760 can be suitably formed.

[0077] Figure 20(b) shows a modified version of Figure 20(a) in which the shape of the bezel has been changed. A slope 765 is provided on the bezel 703b in the part close to the support member 770, and the front elastic body 750 is also attached to the slope 765 so as not to interfere with the support member 770. In addition, in Figure 20(b), the adhesive area between the front elastic body and the bezel can be increased compared to Figure 20(a), making it more difficult for the front elastic body to peel off the bezel.

[0078] As described above, according to this embodiment, by changing the shape of peripheral members such as the front elastic body and support members to form a space into which the front elastic body and support members fit, interference between the support members and the front elastic body can be suppressed even when the bezel is narrowed, thereby suppressing a decrease in display quality.
