[Modes for carrying out the invention]

[0009] [Embodiment 1] One embodiment of this disclosure will be described in detail below.

[0010] (Overall configuration of display device 1) Figure 1 is an exploded perspective view showing a schematic of the display device 1 according to Embodiment 1. The display device 1 is a so-called mini-LED (Light Emitting Diode) type liquid crystal display device. As shown in Figure 1, the display device 1 comprises a display unit 10, a power supply board 50 (circuit board), a liquid crystal control board 55 (circuit board), a main board 60 (circuit board), a stand 21, and a half cabinet 22.

[0011] Figure 2 is an exploded perspective view showing the schematic of the display unit 10. As shown in Figure 2, the display unit 10 comprises a liquid crystal panel 11, a bezel 12, a first optical sheet 13, a second optical sheet 14, an LED substrate 15, and a chassis 30.

[0012] The liquid crystal panel 11 is a display panel that displays images. The LED substrate 15 is a substrate on which a plurality of LEDs 15a (light sources) are arranged on the surface. The LED substrate 15 is arranged on the side opposite to the surface of the liquid crystal panel 11 that displays images. The LED 15a irradiates light toward the liquid crystal panel 11. The liquid crystal panel 11 displays an image by controlling the transmission of the light irradiated from the LED 15a.

[0013] Specifically, the liquid crystal panel 11 has a configuration in which a pair of glass substrates (not shown) with excellent light transmittance are arranged at a predetermined interval, and liquid crystal is encapsulated between the glass substrates. On the glass substrate closer to the LED 15a, there are provided a switching element connected to a source wiring and a gate wiring orthogonal to each other, a pixel electrode connected to the switching element, an alignment film, etc. (all not shown). On the glass substrate farther from the LED 15a, a color filter in which each coloring portion such as R (red), G (green), and B (blue) is arranged in a predetermined array, a counter electrode, an alignment film, etc. are provided (all not shown). Further, polarizing plates (not shown) are arranged on the outer sides of the pair of glass substrates, respectively.

[0014] The bezel 12 defines the outer frame of the liquid crystal panel 11. The bezel 12 is a frame-shaped member arranged on the side of the LED substrate 15 of the liquid crystal panel 11. In the display device 1, the edge portion of the liquid crystal panel 11 and the bezel 12 are bonded together, for example, with double-sided tape. However, the liquid crystal panel 11 and the bezel 12 may be bonded together by another method.

[0015] The first optical sheet 13 and the second optical sheet 14 adjust the light guiding from the LED 15a to the liquid crystal panel 11. The first optical sheet 13 and the second optical sheet 14 are arranged between the bezel 12 and the LED substrate 15. The first optical sheet 13 and the second optical sheet 14 may be appropriately selected from known diffusion sheets, lens sheets, reflective modification sheets, etc. Also, in addition to the first optical sheet 13 and the second optical sheet 14, the display unit 10 may further include another optical sheet.

[0016] The chassis 30 is a housing that houses the first optical sheet 13, the second optical sheet 14, and the LED substrate 15. The chassis 30 is formed of, for example, resin. The chassis 30 is disposed on the side opposite to the surface on which an image is displayed of the liquid crystal panel 11.

[0017] Returning to FIG. 1, the power supply substrate 50 supplies the power input from the outside of the display device 1 to each part of the display device 1. The liquid crystal control substrate 55 controls the operation of the liquid crystal panel 11. The main substrate 60 comprehensively controls the operations of each part included in the display device 1, such as the liquid crystal panel 11, the LED substrate 15, the power supply substrate 50, and the liquid crystal control substrate 55.

[0018] The stand 21 is a base that supports the display unit 10. The half cabinet 22 is a cabinet that houses the power supply substrate 50, the liquid crystal control substrate 55, the main substrate 60, and the like. The half cabinet 22 is attached to a region approximately half on the lower side of the chassis 30 in a state where the display unit 10 is supported by the stand 21. In other words, in a state where the display unit 10 is supported by the stand 21, the half cabinet 22 is not attached to a region approximately half on the upper side of the chassis 30. Thereby, compared with the case where a cabinet is attached to the entire chassis 30, the thickness on the upper side of the display device 1 in a state where the display unit 10 is supported by the stand 21 can be reduced.

[0019] FIG. 3 is a diagram showing the configuration of the back surface of the display device 1. In FIG. 3, the half cabinet 22 is shown in a removed state. As shown in FIG. 3, the display device 1 includes, on the back surface, a reinforcing member 40 and a wiring member 70 in addition to the above-described chassis 30, power supply substrate 50, liquid crystal control substrate 55, and main substrate 60. That is, the power supply substrate 50, the liquid crystal control substrate 55, and the main substrate 60 are disposed on a part of the chassis 30 on the same side as the reinforcing member 40.

[0020] The reinforcing member 40 reinforces the strength of the chassis 30. The reinforcing member 40 also functions as a jig for attaching the half cabinet 22 to the chassis 30. The reinforcing member 40 is positioned on a portion of the chassis 30 opposite to the liquid crystal panel 11 and extends along a first direction parallel to the surface of the chassis 30. In Figure 3, the reinforcing member 40 extends along the direction of the longer side of the chassis 30, which has a substantially rectangular shape. However, the direction in which the reinforcing member 40 extends and its position can be appropriately changed within a range that maintains the strength of the chassis 30. The reinforcing member 40 is preferably made of metal. Specifically, the reinforcing member 40 is made of, for example, aluminum or stainless steel.

[0021] The wiring component 70 is a wiring that connects to the power supply board 50, the liquid crystal control board 55, and the main board 60. The wiring component 70 connected to the power supply board 50 supplies power from the power supply board 50 to the liquid crystal panel 11, LED 15a, liquid crystal control board 55, and the main board 60. The wiring component 70 connected to the main board 60 transmits control signals from the main board 60 to the liquid crystal panel 11, LED 15a, liquid crystal control board 55, and the power supply board 50. The wiring component 70 connected to the liquid crystal control board 55 transmits control signals from the liquid crystal control board 55 to the liquid crystal panel 11.

[0022] Figure 4 is a magnified view of area A1 in Figure 3. As shown in Figure 4, the chassis 30 is provided with multiple connectors 31. The connectors 31 are connected to the liquid crystal panel 11 or LED 15a on the liquid crystal panel 11 side of the chassis 30. By connecting the power supply board 50, the liquid crystal control board 55, and the main board 60 to the connectors 31 using wiring members 70, the power supply board 50, the liquid crystal control board 55, and the main board 60 are connected to the liquid crystal panel 11 or LED 15a via the wiring members 70 and the connectors 31.

[0023] The reinforcing member 40 has a cavity 41 inside. The cavity 41 extends along the direction of the long side of the chassis 30, just like the reinforcing member 40 itself. At least a portion of the wiring member 70 is housed within the cavity 41 of the reinforcing member 40. For example, the wiring member 70 is pulled out of the cavity 41 near the power supply board 50, the liquid crystal control board 55, the main board 60, and the connector 31, while the rest is housed within the cavity 41.

[0024] (Configuration of the reinforcing member 40) Figure 5 is a diagram showing an example of the configuration of the reinforcing member 40 according to Embodiment 1, and is a cross-sectional view of the reinforcing member 40 in a plane perpendicular to the direction in which the cavity 41 extends. In the example shown in Figure 5, the reinforcing member 40 has a bottom plate 42 and a first side plate 43. The bottom plate 42 is a plate-shaped portion facing the chassis 30. In the configuration shown in Figure 5, the bottom plate 42 is joined to the chassis 30. The first side plate 43 is a plate-shaped portion that protrudes from one end of the bottom plate 42 in a direction perpendicular to the direction in which the cavity 41 extends (second direction). In the example shown in Figure 5, the second direction is parallel to the bottom plate 42. In the example shown in Figure 5, the end of the bottom plate 42 from which the first side plate protrudes is the end furthest from the power supply board 50, the liquid crystal control board 55, and the main board 60.

[0025] The reinforcing member 40 further has a top plate 44. The top plate 44 is a plate-shaped portion that extends from the first side plate 43 opposite the bottom plate 42. The top plate 44 is provided with a notch 44a. The notch 44a forms an opening that allows any part of the wiring member 70 to be accommodated from the outside to the inside of the cavity 41.

[0026] A retaining member 49 is provided on the first side plate 43. The retaining member 49 holds the wiring member 70 inside the cavity 41. Specifically, the retaining member 49 comprises a bottom portion 49a joined to the first side plate 43 and a pair of claw portions 49b protruding from the bottom portion 49a. By gripping the wiring member 70 with the claw portions 49b, the wiring member 70 is less likely to fall out of the cavity 41. The retaining member 49 is made of, for example, resin. The retaining member 49 is attached to the first side plate 43 using, for example, double-sided tape.

[0027] The retaining member 49 may be provided at only one location in the direction in which the cavity 41 extends, or it may be provided at predetermined intervals (for example, 5 cm to 10 cm). Alternatively, the retaining member 49 may be provided at any position considering its positional relationship with other components of the display device 1, such as the power supply board 50, the liquid crystal control board 55, and the main board 60.

[0028] Figure 6 is a diagram showing another example of the configuration of the reinforcing member 40 according to Embodiment 1, and is a cross-sectional view of the reinforcing member 40 in a plane perpendicular to the direction in which the cavity 41 extends. As shown in Figure 6, the reinforcing member 40 may not have a top plate 44 and may have a second side plate 45. The second side plate 45 is a plate-shaped portion that protrudes from the other end of the bottom plate 42 in a direction perpendicular to the direction in which the cavity 41 extends. In the example shown in Figure 6, the other end of the bottom plate 42 from which the second side plate 45 protrudes is the end closer to the power supply board 50, the liquid crystal control board 55, and the main board 60. The second side plate 45 is provided with a notch 45a. The notch 45a forms an opening that allows any part of the wiring member 70 to be accommodated from the outside to the inside of the cavity 41. Also, in the example shown in Figure 6, the retaining member 49 is provided on the bottom plate 42.

[0029] The structure of the reinforcing member 40 is not limited to the examples shown in Figures 5 and 6. For example, when the reinforcing member 40 has a top plate 44, the retaining member 49 may be provided on the bottom plate 42. Also, when the reinforcing member 40 has a second side plate 45, the retaining member 49 may be provided on the first side plate 43. Furthermore, when the reinforcing member 40 has a second side plate 45, a notch may be formed in the first side plate 43. In this case, the retaining member 49 may be provided on the bottom plate 42, the top plate 44, or the second side plate 45.

[0030] By housing at least a portion of the wiring member 70 within such a reinforcing member 40, the area required for arranging the wiring member 70 outside the reinforcing member 40 is reduced. Furthermore, as described above, the direction in which the reinforcing member 40 extends and the position of the reinforcing member 40 can be appropriately changed within a range that maintains the strength of the chassis 30. For this reason, the direction in which the wiring member 70 housed within the reinforcing member 40 extends and the position of the wiring member 70 can also be appropriately changed. Consequently, the display device 1 improves the degree of freedom in the layout of the wiring member 70.

[0031] The wiring member 70 housed in the cavity 41 may supply power from the power supply board 50 to the liquid crystal panel 11. The current flowing through the wiring member 70 that supplies power from the power supply board 50 to the liquid crystal panel 11 is larger than the current flowing through the wiring member 70 described in (i) and (ii) below, for example.

[0032] (i) Wiring member 70 that supplies power from power supply board 50 to main board 60 (ii) Wiring member 70 that transmits control signals from the main board 60 to the liquid crystal panel 11 Therefore, in the wiring member 70 that supplies power from the power supply board 50 to the liquid crystal panel 11, the EMI (Electromagnetic Interference) caused by unwanted radiation resulting from the current flowing through the wiring member 70, particularly the ripple contained in the current, also increases.

[0033] The wiring member 70 housed in the cavity 41 is covered in part in the circumferential direction, when the extension direction of the cavity 41 is axial, by the bottom plate 42, the first side plate 43, and either the top plate 44 or the second side plate 45. If the reinforcing member 40 is made of metal, the reinforcing member 40 blocks at least a portion of the EMI. Therefore, by housing the wiring member 70 that supplies power from the power supply board 50 to the liquid crystal panel 11 in the cavity 41, the impact of EMI on other components of the display device 1 can be reduced. However, the wiring member 70 housed in the cavity 41 is not limited to the wiring member 70 that supplies power from the power supply board 50 to the liquid crystal panel 11. The wiring member 70 of (i) or (ii) above, or yet another wiring member 70, may be housed in the cavity 41.

[0034] The display device relating to this disclosure is not limited to a mini-LED liquid crystal display device. The display device relating to this disclosure may be a liquid crystal display device that is not mini-LED, or an organic EL (Electro-Luminescence) display device. If the display device is an organic EL display device, it does not include an LED substrate 15 and a liquid crystal control substrate 55, and instead of a liquid crystal panel 11, it includes a self-emitting organic EL panel as the display panel. The wiring member 70 connects the power supply substrate 50 and the main substrate 60 to the organic EL panel. Even in such a display device, the degree of freedom in the layout of the wiring member 70 is improved by housing at least a part of the wiring member 70 in the cavity 41.

[0035] Furthermore, as described above, the reinforcing member 40 reinforces the chassis 30 and functions as a jig for attaching the half cabinet 22 to the chassis 30. In other words, the display device 1 is equipped with the reinforcing member 40 regardless of the layout of the wiring members 70. Therefore, there is no need to add any unnecessary components to the display device 1 in order to accommodate the wiring members 70. Also, the reinforcing member 40 is a separate component from the chassis 30. For this reason, no special processing is required for the chassis 30 to improve the flexibility of the layout of the wiring members 70.

[0036] [Embodiment 2] Other embodiments of this disclosure are described below. For the sake of clarity, components having the same function as those described in the above embodiments are denoted by the same reference numerals, and their descriptions are not repeated.

[0037] Figure 7 is a diagram showing an example of the configuration of a reinforcing member 40A according to Embodiment 2, and is a cross-sectional view of the reinforcing member 40A in a plane perpendicular to the direction in which the cavity 41 extends. As shown in Figure 7, the reinforcing member 40A has a bottom plate 42, a first side plate 43, a second side plate 45, and a top plate 44. In the reinforcing member 40A, the top plate 44 connects the first side plate 43 and the second side plate 45 to each other. The top plate 44 is provided with a notch 44a. The notch 44a forms an opening that allows any part of the wiring member 70 to be accommodated from the outside to the inside of the cavity 41.

[0038] Figure 8 is a diagram showing another example of the configuration of the reinforcing member 40A according to Embodiment 2, and is a cross-sectional view of the reinforcing member 40A in a plane perpendicular to the direction in which the cavity 41 extends. In the example shown in Figure 8, the reinforcing member 40A does not have a notch 44a in the top plate 44, but a notch 45a is provided in the second side plate 45.

[0039] The configuration of the reinforcing member 40A is not limited to those shown in Figures 7 and 8. For example, the first side plate 43 may have a notch. Also, notches may be provided in two or more adjacent members among the first side plate 43, the top plate 44, and the second side plate 45. For example, the top plate 44 may have a notch 44a and the second side plate 45 may have a notch 45a.

[0040] Unlike the reinforcing member 40 described in Embodiment 1, the reinforcing member 40A has a bottom plate 42, a first side plate 43, a second side plate 45, and a top plate 44. Therefore, the wiring member 70 housed in the cavity 41 of the reinforcing member 40A is less likely to fall out of the cavity 41 compared to the wiring member 70 housed in the cavity 41 of a reinforcing member 40 that does not have a second side plate 45 or a top plate 44. For this reason, the reinforcing member 40A does not require a retaining member 49. Consequently, by including the reinforcing member 40A in the display device 1, the number of parts of the display device 1 can be reduced compared to the case where the display device 1 is equipped with the reinforcing member 40.

[0041] Furthermore, the wiring member 70 housed in the cavity 41 of the reinforcing member 40A is more extensively covered by the reinforcing member 40A compared to the wiring member 70 housed in the cavity 41 of the reinforcing member 40. As a result, in the display device 1 equipped with the reinforcing member 40A, the EMI caused by unwanted radiation resulting from the current flowing through the wiring member 70 is reduced compared to the EMI in the display device 1 equipped with the reinforcing member 40.

[0042] Figure 9 shows a modified example of the reinforcing member 40A according to Embodiment 2, and is a cross-sectional view of the reinforcing member 40A in a plane perpendicular to the direction in which the cavity 41 extends. In the modified example shown in Figure 9, a fall prevention member 48 is provided in the notch 44a of the reinforcing member 40A. The fall prevention member 48 is provided in at least a portion of the cavity 41 in the direction of extension. The position where the fall prevention member 48 is provided in the direction of extension of the cavity 41 may be the same as the position where the retaining member 49 is provided as described in Embodiment 1. Alternatively, the fall prevention member 48 may be provided over the entire length of the cavity 41 in the direction of extension.

[0043] The anti-detachment member 48 closes the opening formed by the notch 44a at the location where the anti-detachment member 48 is provided, making it difficult for the wiring member 70 to fall out of the cavity 41 at that location. The anti-detachment member 48 is made of a flexible material. Therefore, by applying an external force to the anti-detachment member 48 and deforming it, the wiring member 70 can be accommodated in the cavity 41 even at the location where the anti-detachment member 48 is provided.

[0044] [Embodiment 3] Further embodiments of this disclosure are described below.

[0045] Figure 10 is a diagram showing an example of the configuration of a reinforcing member 40B according to Embodiment 3, and is a cross-sectional view of the reinforcing member 40B in a plane perpendicular to the direction in which the cavity 41 extends. As shown in Figure 10, the reinforcing member 40B has a bottom plate 42, a first side plate 43, a second side plate 45, and a top plate 44. In the reinforcing member 40B, the top plate 44 connects the first side plate 43 and the second side plate 45 to each other. The top plate 44 is provided with a pull-out hole 44b. The pull-out hole 44b is a hole that allows the end of the wiring member 70 to be pulled out from the inside of the cavity 41 to the outside. The pull-out hole 44b is not included in the cross-section of the reinforcing member 40B shown in Figure 10.

[0046] Figure 11 is a plan view of the reinforcing member 40B in the vicinity of the power supply board 50. As shown in Figure 11, the lead-out holes 44b are formed in the vicinity of the power supply board 50. The lead-out holes 44b are also formed in the vicinity of components to which wiring members 70, at least a portion of which is housed inside the cavity 41, are connected, such as the connector 31 (see Figure 4).

[0047] When the wiring member 70 connecting the power supply board 50 and the connector 31 is housed in the cavity 41, one end of the wiring member 70 is inserted into the cavity 41 through one of the lead-out holes 44b, and the other end is pulled out of the cavity 41 through the other lead-out hole 44b. As a result, both ends of the wiring member 70 are pulled out from their respective lead-out holes 44b.

[0048] Figure 12 is a diagram showing another example of the configuration of the reinforcing member 40B according to Embodiment 3, and is a cross-sectional view of the reinforcing member 40B in a plane perpendicular to the direction in which the cavity 41 extends. In the example shown in Figure 12, the top plate 44 does not have a pull-out hole 44b, and the second side plate 45 has a pull-out hole 45b. Alternatively, in the reinforcing member 40B, neither the pull-out holes 44b nor 45b may be provided, and a pull-out hole may be provided in the first side plate 43.

[0049] Furthermore, in the reinforcing member 40B, it is not necessarily required that only one of the pull-out holes 44b or 45b be formed. For example, a pull-out hole 44b may be provided in the top plate 44 near the power supply board 50, and a pull-out hole 45b may be provided near the connector 31. The choice of which of the first side plate 43, the second side plate 45, and the top plate 44 to provide the pull-out holes can be appropriately determined according to the positional relationship of each component of the display device 1.

[0050] The wiring member 70 housed in the cavity 41 of the reinforcing member 40B is covered by the reinforcing member 40B on its entire periphery, except for the vicinity of the lead-out hole. Therefore, in the display device 1 equipped with the reinforcing member 40B, the EMI caused by unwanted radiation resulting from the current flowing through the wiring member 70 is further reduced than in the display device 1 equipped with the reinforcing member 40A. The reinforcing member 40B can be suitably used, for example, when the current flowing through the wiring member 70 is large, or when components susceptible to EMI (e.g., the liquid crystal control board 55 and the main board 60) are densely clustered near the reinforcing member 40B.

[0051] 〔summary〕 A display device according to Embodiment 1 of the present disclosure comprises: a display panel for displaying an image; a chassis disposed on the side of the display panel opposite to the side on which the image is displayed; a reinforcing member disposed on a part of the chassis opposite to the display panel and having a cavity extending along a first direction parallel to the surface of the chassis; a circuit board disposed on a part of the chassis on the same side as the reinforcing member and connected to the display panel; and a wiring member connected to the circuit board, wherein at least a portion of the wiring member is housed in the cavity of the reinforcing member.

[0052] According to the above configuration, in the display device, the reinforcing member and the circuit board are arranged on the chassis opposite the display panel. At least a portion of the wiring members connected to the circuit board are housed in the cavity of the reinforcing member. The position of the reinforcing member can be changed as appropriate within a range that maintains the strength of the chassis. Therefore, the degree of freedom in the layout of the wiring members is improved.

[0053] In a display device according to aspect 2 of the present disclosure, the reinforcing member has a bottom plate facing the chassis, a first side plate protruding from one end of the bottom plate in a second direction perpendicular to the first direction, and further comprises a second side plate protruding from the other end of the bottom plate in the second direction, and a top plate extending from the first side plate facing the bottom plate, wherein a notch is provided in the second side plate or the top plate, the notch forms an opening that allows any portion of the wiring member to be accommodated from the outside to the inside of the cavity, and a holding member for holding the wiring member inside the cavity is provided in the bottom plate, the first side plate, the second side plate, or the top plate.

[0054] According to the above configuration, the reinforcing member of the display device comprises a bottom plate, a first side plate, and either a second side plate or a top plate. Furthermore, a holding member for holding wiring members is provided on the bottom plate, the first side plate, the second side plate, or the top plate. Therefore, any part of the wiring member can be housed in the cavity from the outside through an opening formed by a notch provided in the second side plate or top plate, and held by the holding member.

[0055] In the display device according to embodiment 3 of the present disclosure, the reinforcing member may have the top plate, the top plate may be provided with the notch, and the first side plate may be provided with the holding member.

A pull-out hole is provided in either the bottom plate, the first side plate, the second side plate, or the top plate, allowing the end of the wiring member to be pulled out from the inside of the cavity to the outside. As a result, the wiring member housed in the cavity is covered by the reinforcing member, except for the vicinity of the pull-out hole. Consequently, the influence of unwanted radiation on other components is reduced.

[0065] In the display device according to aspect 8 of the present disclosure, the pull-out hole may be provided on the top plate.

[0066] With the above configuration, the ends of the wiring components can be pulled out from the inside of the cavity to the outside through the pull-out holes provided in the top panel.

[0067] In the display device according to aspect 9 of the present disclosure, the circuit board is a power supply board that supplies power to the display panel, and the wiring member may supply power from the power supply board to the display panel.

[0068] With the above configuration, the current flowing through the wiring component is larger compared to, for example, when the wiring component transmits control signals to the display panel. As a result, EMI generated in the wiring component also increases. By housing such a wiring component in a cavity, at least a portion of the wiring component's periphery is covered by the reinforcing component. Therefore, the above-mentioned EMI can be reduced.

[0069] A display device according to embodiment 10 of the present disclosure further comprises a light source disposed on the display panel side of the chassis and irradiating light toward the display panel, wherein the display panel may be a liquid crystal panel that controls the transmission of light from the light source.
