[0008] Hereinafter, an example of a preferred embodiment of the present invention will be described. However, the following embodiment is merely an example, and the present invention is not limited to the following embodiment.

[0009] FIG. 1 is a schematic plan view of a display device 1 according to this embodiment. FIG. 2 is a schematic plan view of a chassis 200 in this embodiment. FIG. 3 is a schematic cross-sectional view of a portion of the display device 1 in region III of FIG. 2. FIG. 4 is a schematic perspective view of a portion of the chassis 200 in this embodiment. FIG. 5 is a schematic cross-sectional view of a portion of the display device 1 taken along line VV in FIG. 3. FIG. 6 is a schematic cross-sectional view of a portion of the display device 1 taken along line VI-VI in FIG. 3.

[0010] In the following description, the thickness direction (depth direction) of the display panel 510 shown in Figures 5 and 6 is referred to as the z-axis direction. The display surface side (front side) of the display panel 510 is referred to as the z1 side, and the back side is referred to as the z2 side. The direction perpendicular to the z-axis direction which is the thickness direction of the display panel 510, and along the longitudinal direction of the display panel 510 (width direction) is referred to as the x-axis direction, and the direction along the lateral direction (height direction) is referred to as the y-axis direction. The x-axis and y-axis directions are mutually perpendicular. Also, viewing along the z-axis direction is referred to as "planar view".

[0011] The display device 1 shown in Fig. 1 is a device for displaying images, characters, etc. The display device 1 may be, for example, a display, etc. In this embodiment, the display device 1 is a television receiving device having a tuner capable of receiving television signals.

[0012] The display device 1 includes a panel assembly 100 shown in FIG. 1 and a chassis 200 shown in FIG.

[0013] (Panel Assembly 100) As shown in FIGS. 5 and 6, the panel assembly 100 includes a display panel 510 and a frame 530.

[0014] The display panel 510 may be, for example, a liquid crystal display panel, an OLED (Organic Light Emitting Diode) display panel, a quantum dot light emitting diode (QLED) display panel, a plasma display panel, etc. In the following, in this embodiment, an example in which the display panel 510 is a liquid crystal display panel will be described.

[0015] A backlight 520 is disposed on the z2 side (rear side) in the z-axis direction, which is the thickness direction of the display panel 510. The backlight 520 emits light toward the display panel 510. The backlight 520 is attached to the chassis 200. Note that when a self-luminous display panel is used, the backlight is not necessarily required.

[0016] (Frame 530) The display panel 510 is attached to a frame 530. As shown in Fig. 1, in this embodiment, the display panel 510 and the backlight 520 each have a rectangular shape in a plan view, and the frame 530 is provided in a frame shape so as to surround the display panel 510 and the backlight 520. The peripheral portions of the display panel 510 and the backlight 520 are attached to the frame 530. Therefore, as shown in Figs. 5 and 6, the frame 530 constitutes substantially the entire side surface of the display device 1.

[0017] In the present invention, the frame does not necessarily have to be provided so as to surround the entire periphery of the display panel. The frame only needs to be attached to at least a part of the peripheral portion of the display panel. For example, the frame may be attached to three or less of the four edge portions of a display panel having a rectangular shape in a plan view. For example, the frame may be attached to the corners of the display panel.

[0018] The frame 530 may be made of a resin member having a coating film formed on its surface.

[0019] As shown mainly in Fig. 5, frame 530 has frame main body 531, attachment portion 532, and first protrusion portion 533. As shown in Fig. 1, frame main body 531 is disposed on the outer side of display panel 510 in plan view. Specifically, frame main body 531 is disposed in a frame shape so as to surround display panel 510 in plan view.

[0020] The term "outside" refers to the side away from the centroid. Specifically, the term "outside" in this embodiment refers to the side away from the centroid C of the display panel 510 shown in FIG.

[0021] As shown in FIGS. 5 and 6, the frame body 531 has a first portion 531a and a second portion 531b.

[0022] The first portion 531a includes a portion located at the same height as the display panel 510 in the z-axis direction.

[0023] An attachment portion 532 is connected to the first portion 531a of the frame main body 531. The attachment portion 532 extends inward from the first portion 531a along the x-axis direction. The display panel 510 and the like are attached to the attachment portion 532.

[0024] The second portion 531b is connected to the z2 side end (rear side end) of the first portion 531a. Specifically, the second portion 531b extends from the outer portion of the first portion 531a toward the z2 side (rear side). The second portion 531b is thinner than the first portion 531a.

[0025] The first protrusion 533 is connected to the second portion 531b. The first protrusion 533 may be connected to a portion of the second portion 531b that is closer to the tip side (z2 side) than the center portion in the z-axis direction.

[0026] The first protrusion 533 may be provided around the entire circumference, but in this embodiment, as shown in Fig. 3, the first protrusion 533 is connected to only a portion of the second portion 531b in the circumferential direction. As shown in Fig. 5, the first protrusion 533 protrudes inward from the inner circumferential surface of the second portion 531b. The cross-sectional shape of the first protrusion 533 is substantially triangular.

[0027] The first protrusion 533 has an upper surface 533a located on the z1 side in the z-axis direction and a lower surface 533b located on the z2 side. The upper surface 533a faces the z1 side. The upper surface 533a is a substantially flat surface extending along the x-axis direction and the y-axis direction.

[0028] The lower surface 533b constitutes a second inclined surface. The lower surface 533b is a surface inclined with respect to the z-axis direction. Specifically, in this embodiment, the lower surface 533b is a substantially flat surface inclined with respect to the z-axis direction. The lower surface 533b is inclined outward from the z1 side toward the z2 side in the z-axis direction, which is the thickness direction. In other words, the lower surface 533b is inclined inward from the z2 side toward the z1 side.

[0029] In the present invention, the second inclined surface does not necessarily have to be a substantially flat surface. The second inclined surface may be, for example, a curved surface. More specifically, the second inclined surface may be, for example, a curved inclined surface that protrudes toward the z2 side.

[0030] (Chassis 200) 5 and 6, the chassis 200 is disposed on the z2 side (rear side) in the z-axis direction, which is the thickness direction of the display panel 510. Specifically, in this embodiment, the chassis 200 is disposed inside the frame 530 on the z2 side of the display panel 510. The sides of the chassis 200 are covered by the frame 530.

[0031] The material of the chassis 200 is not particularly limited. The chassis 200 may be made of, for example, a resin member. The resin member constituting the chassis 200 may be coated with a paint film.

[0032] As shown in FIGS. 2, 5 and 6, the chassis 200 includes a chassis body 210 and a holder 220. The chassis body 210 includes a holder 220. The holder 220 is made of a plastic.

[0033] The chassis body 210 covers substantially the entire rear surface of the display panel 510. The chassis body 210 has approximately the same shape as the display panel 510. The shape of the chassis body 210 in a plan view is substantially rectangular.

[0034] The chassis body 210 has a flat first portion 211 extending along the x-axis and y-axis directions, and a second portion 212 extending from the periphery of the first portion 211 toward the z1 side (the display panel 510 side) in the z-axis direction. The second portion 212 extends along the z-axis direction. As shown in FIGS. 5 and 6, the tip portion of the second portion 212 on the z1 side extends to a side of the panel assembly 100. Specifically, the tip portion of the second portion 212 on the z1 side is located to the side of the backlight 520.

[0035] 3, 5, and 6, when viewed from the z2 side along the z-axis direction, a gap G is formed between the chassis 200 and the frame 530. In detail, as shown in Fig. 5 and 6, when viewed from the z2 side, the gap G extends along the z-axis direction between the second portion 212 of the chassis 200 and the second portion 531b of the frame 530.

[0036] (Holder 220) 2, the holder 220 is fixed to the chassis body 210. Specifically, a plurality of holders 220 are fixed to the chassis body 210. More specifically, four holders 220 are fixed to the chassis body 210. A holder 220 is fixed to each of the four end portions of the chassis body 210.

[0037] 5, each of the plurality of holders 220 is engaged with a frame 530. By the plurality of holders 220 engaging with the frame 530, the panel assembly 100 is fixed to the chassis 200.

[0038] The configuration of the holder 220 will be described in further detail with reference to FIGS.

[0039] As shown in FIG. 3, the holder 220 has a fixed portion 221 and a displacement portion 222.

[0040] The fixed portion 221 is directly fixed to the chassis body 210 .

[0041] The fixed portion 221 has a linear portion 221a, a first end portion 221b, and a second end portion 221c. The linear portion 221a is a linear portion extending along the direction in which the end side of the chassis main body 210 extends.

[0042] A first end 221b is connected to one end of the linear portion 221a in the longitudinal direction, and a second end 221c is connected to the other end of the linear portion 221a. In a plan view, each of the first end 221b and the second end 221c extends outward beyond the linear portion 221a.

[0043] The displacement portion 222 is connected to the outer end 221b1 of the first end 221b and the outer end 221c1 of the second end 221c. The displacement portion 222 is not directly fixed to the chassis body 210 and is deformable. The displacement portion 222 is provided apart from the linear portion 221a. A slit S is formed between the displacement portion 222 and the linear portion 221a. Therefore, the displacement portion 222 is deformed starting from the outer end 221b1 and the outer end 221c1, so that the central portion 222a in the longitudinal direction of the displacement portion 222 (the direction in which the edge of the chassis body 210 extends) can be displaced inward or outward. Therefore, the central portion 222a in the longitudinal direction of the displacement portion 222 can be displaced in a direction away from and toward the frame 530. The displacement portion 222 can be deformed into, for example, a bow shape as shown by the dashed line in FIG. 3. As the displacement portion 222 changes from a linear state to a bow shape, the central portion 222a is displaced inward in a plan view and moves away from the frame 530.

[0044] As shown in FIG. 4, the second portion 212 of the chassis body 210 has through holes 213 formed therein, which penetrate the second portion 212 in the thickness direction. Specifically, the through holes 213 are provided at positions of the second portion 212 corresponding to the portions where the multiple holders 220 are provided. Therefore, the holder 220 includes an exposed portion 220a exposed from the chassis body 210. The exposed portion 220a of the holder 220 exposed from the chassis body 210 is composed of a central portion 222a. As shown in FIG. 5 and FIG. 6, a frame 530 is located outside the exposed portion 220a. The frame 530 covers the outside of the exposed portion 220a.

[0045] As shown mainly in FIG. 4 and FIG. 5, the holder 220 has a second protrusion 230. Specifically, the second protrusion 230 is provided on the exposed portion 220a constituted by the central portion 222a. Therefore, the second protrusion 230 is located at a position away from the outer end 221b1 and the outer end 221c1 which are the connection portions of the displacement portion 222 with the fixed portion 221. Specifically, the second protrusion 230 is located between the outer end 221b1 and the outer end 221c1 in the longitudinal direction of the displacement portion 222. More specifically, the second protrusion 230 is provided at approximately the central portion of the displacement portion 222 in the longitudinal direction of the displacement portion 222.

[0046] As shown in Fig. 5, the second protrusion 230 protrudes toward the frame 530. As shown in Fig. 5, the second protrusion 230 is located on the z1 side (front surface side, display panel 510 side) in the z-axis direction, which is the thickness direction, of the first protrusion 533 protruding toward the holder 220. The second protrusion 230 and the first protrusion 533 are engaged with each other, whereby the chassis body 210 and the panel assembly 100 are fixed to each other so as not to be substantially displaceable in the z-axis direction.

[0047] As described above, the second protrusion 230 is provided on the central portion 222a. The central portion 222a is displaceable in a direction away from and toward the frame 530. Therefore, the second protrusion 230 is displaceable in a direction away from and toward the frame 530.

[0048] As shown in FIG. 5, the second convex portion 230 has an upper surface 231 and a lower surface 232. The upper surface 231 is located closer to the z1 side (front surface side) in the z-axis direction than the lower surface 232. The upper surface 231 is an inclined surface. Specifically, the upper surface 231 constitutes a third inclined surface that inclines outward from the z1 side toward the z2 side in the z-axis direction. In this embodiment, the upper surface 231 is constituted by a curved surface. Specifically, the upper surface 231 is constituted by a convex surface that protrudes toward the z1 side. However, the present invention is not limited to this configuration. The upper surface 231 may be constituted by, for example, a flat surface.

[0049] 3, the dimension along the longitudinal direction of the first protrusion 533 is substantially the same as the dimension along the longitudinal direction of the second protrusion 230. In particular, the dimension along the longitudinal direction of the second protrusion 230 is slightly shorter than the dimension along the longitudinal direction of the first protrusion 533.

[0050] As shown in FIG. 3, the first protrusion 533 has a substantially rectangular shape in a plan view.

[0051] As shown in FIG. 3, FIG. 4, and FIG. 6, the displacement portion 222 is provided with third convex portions 241, 242. Specifically, in this embodiment, the displacement portion 222 is provided with a plurality of third convex portions 241, 242. The plurality of third convex portions 241, 242 have inclined surfaces (first inclined surfaces) 241a, 242a, respectively. The inclined surfaces 241a, 242a extend outward from the z2 side toward the z1 side in the z-axis direction. In this embodiment, the inclined surfaces 241a, 242a are flat surfaces. However, the inclined surfaces 241a, 242a do not have to be flat surfaces. For example, they may be curved surfaces such as convex surfaces or concave surfaces.

[0052] At least a part of the inclined surfaces 241a, 242a is visible through the gap G when viewed from the z2 side along the z-axis direction. In other words, when viewed from the z2 side along the z-axis direction, a gap G that exposes the inclined surfaces 241a, 242a is formed between the chassis 200 and the frame 530.

[0053] 3 and 4, in this embodiment, the third convex portion 241 and the third convex portion 242 are provided on both sides of the second convex portion 230. In particular, the third convex portion 241 and the third convex portion 242 are provided on both sides of the second convex portion 230 in the extending direction of the displacement portion 222. Therefore, the third convex portions 241, 242 are provided between a fixed end on one side of the displacement portion 222 and the second convex portion 230, and between a fixed end on the other side of the displacement portion 222 and the second convex portion 230, respectively.

[0054] (A process of attaching the panel assembly 100 to the chassis 200) 7 and 8 are schematic cross-sectional views for explaining the process of attaching the panel assembly 100 to the chassis 200. Next, the process of attaching the panel assembly 100 to the chassis 200 will be explained with reference to FIGS.

[0055] 7, the panel assembly 100 and the chassis 200 are aligned. At this time, the first protrusion 533 of the frame 530 constituting a part of the panel assembly 100 and the second protrusion 230 of the holder 220 constituting a part of the chassis 200 butt against each other in the z-axis direction.

[0056] When the panel assembly 100 is pressed relatively toward the chassis 200 from this state, the upper surface 231 of the second convex portion 230 is pressed by the lower surface 533b, which serves as the inclined surface, of the first convex portion 533, as shown in Fig. 8, and the displacement portion 222 is elastically deformed into a bow shape as shown by the dashed line in Fig. 3, so that the second convex portion 230 moves inward. When the panel assembly 100 is further pressed relatively toward the chassis 200 from this state, the first convex portion 533 gets over the second convex portion 230, and then the second convex portion 230 moves outward again, and the panel assembly 100 and the chassis 200 are assembled as shown in Fig. 5.

[0057] In this way, in the display device 1, the second protrusion 230 is provided so as to be displaceable in a direction away from the frame 530. Therefore, compared to a case where the displacement portion is directly fixed to the chassis and the second protrusion cannot be substantially displaced in a direction away from the frame, it is possible to suppress deformation of the frame 530 when the first protrusion 533 climbs over the second protrusion 230 to assemble the panel assembly 100 to the chassis 200. Therefore, it is possible to suppress deformation, discoloration, and damage of the frame 530 that constitutes the appearance of the display device 1. Therefore, the display device 1 can be easily manufactured without impairing the appearance.

[0058] From the viewpoint of effectively suppressing plastic deformation of the displacement portion 222, it is preferable that both ends in the longitudinal direction of the displacement portion 222 are fixed to the fixed portion 221. It is more preferable that both ends in the longitudinal direction of the displacement portion 222 are fixed to the fixed portion 221, and that the second convex portion 230 is provided in an approximately central portion in the longitudinal direction of the displacement portion 222. In this case, the amount of deformation per unit length of the displacement portion 222 accompanying the displacement of the second convex portion 230 can be made smaller.

[0059] In the display device 1, at least one of the upper surface 231 of the second protrusion 230 and the lower surface 533b of the first protrusion 533 is configured as an inclined surface inclined with respect to the z-axis direction, which is the thickness direction. Therefore, the force required to displace the second protrusion 230 inward when pressing the panel assembly 100 against the chassis 200 is reduced. Therefore, the assembly of the panel assembly 100 and the chassis 200 is easy, and the ease of manufacture of the display device 1 is further improved.

[0060] In the display device 1, since both the upper surface 231 of the second protrusion 230 and the lower surface 533b of the first protrusion 533 are inclined surfaces, the upper surface 231 and the lower surface 533b slide easily when the panel assembly 100 is inserted into the chassis 200, and the frictional force generated can be reduced. Therefore, the assembly of the panel assembly 100 and the chassis 200 is made even easier.

[0061] Furthermore, in this embodiment, at least one of the second inclined surface formed by the lower surface 533b of the first convex portion 533 and the third inclined surface formed by the upper surface 231 of the second convex portion 230 has a curved portion. Therefore, the contact area between the second inclined surface and the third inclined surface when the panel assembly 100 is assembled to the chassis 200 can be reduced. Therefore, the frictional force generated between the second inclined surface and the third inclined surface can be further reduced. Therefore, the force pressing the panel assembly 100 against the chassis 200 can be further reduced. Therefore, the ease of manufacture of the display device 1 is further improved. From this viewpoint, it is more preferable that at least one of the second inclined surface and the third inclined surface is curved and the other is flat.

[0062] (Process of removing the panel assembly 100 from the chassis 200) 9 and 10 are schematic cross-sectional views illustrating the process of removing the panel assembly 100 from the chassis 200. As shown in FIG.

[0063] For example, when repairing or maintaining the display device 1, it may be necessary to remove the chassis 200 from the panel assembly 100. Next, the process of removing the panel assembly 100 from the chassis 200 will be described with reference mainly to Figures 9 and 10.

[0064] As shown in FIG. 9, when removing the panel assembly 100 from the chassis 200, first, a jig 900 is inserted into the gap G. By pressing the inclined surface 241a of the third protrusion 241 with the jig 900, the central portion 222a of the displacement portion 222 can be displaced inward together with the third protrusion 241 as shown in FIG. 10. By doing so, the displacement portion 222 is elastically deformed into a bow shape shown by a dashed line in FIG. 3. This allows the second protrusion 230 provided on the central portion 222a of the displacement portion 222 to be displaced inward to the state shown in FIG. 8. As a result, the engagement between the second protrusion 230 and the first protrusion 533 is released. Thus, the panel assembly 100 can be removed from the chassis 200.

[0065] In this way, in the display device 1, a third convex portion 241 having an inclined surface 241a is provided, and a gap G is formed to expose the inclined surface 241a, so that the panel assembly 100 can be easily removed from the chassis 200 using the jig 900.

[0066] From the viewpoint of displacing the third convex portion 241 by the jig 900, the inclined surface 241a may have any shape as long as it is inclined with respect to the z-axis direction. However, from the viewpoint of reducing the maximum stress that must be applied to the jig 900, it is preferable that the inclined surface 241a be a flat surface.

[0067] In the display device 1, the third protrusions 241, 242 are provided on both sides of the second protrusion 230. Therefore, by displacing the multiple third protrusions 241, 242 using the jig 900, the second protrusion 230 can be displaced more smoothly.

[0068] Below, a description will be given of modified examples of the preferred embodiment of the present invention. In the following description, components having substantially the same functions as those in the above embodiment will be referred to by the same reference numerals, and the description will be omitted. In addition, in the following description of the modified examples, only the parts different from the above embodiment will be described, and the description of the above embodiment will be referred to for the description of the other parts.

[0069] (Modification) In the display device 1 according to the embodiment described above, an example has been described in which, in a plan view, both ends of the displacement portion 222 in the longitudinal direction are supported by the fixed portion 221. However, the manner in which the displacement portion 222 is fixed to the fixed portion 221 is not particularly limited to this configuration.

[0070] Fig. 11 is a schematic cross-sectional view of a portion of a display device in a first modified example. In the example shown in Fig. 11, the displacement portion 222 is fixed by the fixing portion 221 only on the y2 side in the y-axis direction, which is the longitudinal direction of the displacement portion 222 in a plan view. In the first modified example, the displacement portion 222 is a cantilever beam. In this case, the stress required to displace the second protrusion 230 is reduced. In other words, the second protrusion 230 is more likely to be displaced with a small stress. This makes it even easier to attach the panel assembly 100 to the chassis 200.

[0071] In the above embodiment and the first modified example, an example has been described in which at least one of both ends in the longitudinal direction of the displacement portion 222 in a plan view is fixed by the fixing portion 221. However, the present invention is not limited to this configuration.

[0072] FIG. 12 is a schematic cross-sectional view of a part of a display device in a second modified example. In the example shown in FIG. 12, the fixed portion 221 is provided at the z2-side end (lower end) of the displacement portion 222 in the z-axis direction. That is, the z2-side end of the displacement portion 222 is fixed to the chassis 200 via the fixed portion 221. Therefore, the z1-side portion of the displacement portion 222 that is far from the fixed portion 221 is displaced relatively large, and the connection portion with the fixed portion 221 is not substantially displaced. The second convex portion 230 is provided at the z1-side end of the displacement portion 222, but the z1-side end moves along the circumferential direction with the connection portion with the fixed portion 221 as the center. In this case, it is not necessarily necessary to provide the fixed portion 221 on the outside of the displacement portion 222 in the y-axis direction. Therefore, the dimension of the holder 220 along the y-axis direction can be increased.

[0073] In addition, the position where the fixed portion 221 is provided with respect to the displacement portion 222 in the y-axis direction is not particularly limited. For example, the displacement portion 222 may be provided in substantially the entire area where the fixed portion 221 is provided in the y-axis direction, or may be provided only in a part of the area. For example, the displacement portion 222 may be provided in at least a part of the area where the second convex portion 230 is provided in the y-axis direction. For example, the displacement portion 222 may be connected to at least one of both ends of the displacement portion 222 in the y-axis direction. In this case, the second convex portion 230 is easily displaced by a small force.

[0074] In the above embodiment, an example has been described in which the third convex portions 241, 242 are disposed on both sides of the region in which the first convex portion 533 and the second convex portion 230 face each other in the z-axis direction in plan view. However, in the present invention, the position at which the third convex portion is provided is not particularly limited.

[0075] For example, multiple pairs of convex portions, each of which is a pair of a first convex portion 533 and a second convex portion 230 facing each other in the z-axis direction, may be provided along the y-axis direction, and a third convex portion 241 may be provided between adjacent pairs of convex portions in the y-axis direction.

[0076] 13, the third convex portion 241 may be coaxially located on the z2 side of the second convex portion 230. In this case, it is preferable that the distance (a) between the second convex portion 230 and the third convex portion 241 in the z-axis direction is equal to or greater than the dimension (b) of the first convex portion 533 in the z-axis direction (a>b).

[0077] In the above embodiment, an example has been described in which the holder 220 is provided on each of the four end sides of the rectangular chassis body 210. However, the present invention is not limited to this configuration. When the chassis body 210 is rectangular, it is preferable that the holder 220 is provided on at least one of the four end sides, and it is more preferable that the holder 220 is provided on at least two opposing end sides. For example, as shown in FIG. 14, the holder 220 may be provided on three end sides of the rectangular chassis body 210.

[0078] Furthermore, a plurality of holders 220 may be provided on one end side of the chassis body 210 .

[0079] As shown in Fig. 6, in the above embodiment, an example has been described in which the inclined surfaces 241a, 242a are inclined along the z-axis direction, and the gap G is provided linearly along the z-axis direction. However, the present invention is not limited to this configuration. The inclined surfaces and gap of the third convex portion may be provided in such a manner that the second convex portion 230 is displaced by inserting a jig through the gap and pressing the inclined surfaces. For example, the inclined surfaces of the third convex portion may be inclined with respect to the y-axis direction, and the gap may be provided along the y-axis direction.

[0080] The present invention is not limited to the above-described embodiment and may be modified, and the above configurations may be replaced with substantially the same configurations, configurations that achieve the same effects, or configurations that can achieve the same purpose.
