Embodiment 1）

[0066] [Structure of Display Device]

[0067] First, refer to Figure 1 to Figure 7 , the configuration of the display device according to Embodiment 1 of the present invention will be described. figure 1 It is a perspective view showing the front side of the display device according to Embodiment 1 of the present invention. figure 2 is showing figure 1 Oblique view of the back side of the display device. image 3 is showing figure 1 A plan view of the back side of the display device. Figure 4 is showing figure 1 A plan view of the interior of the display device. Figure 5 yes Figure 4 A cross-sectional view of the main part of the display device cut along line A-A in . Figure 6 It is a perspective view of main parts showing a state in which the backlight is disassembled. Figure 7 It is an enlarged plan view showing a slit and its peripheral portion.

[0068] The display device 2 shown in the drawing includes a housing 4 , a liquid crystal panel 6 (constituting ...

Embodiment 2）

[0093] Next, refer to Figure 9 as well as Figure 10 , the structure of the display device according to Embodiment 2 of the present invention will be described. Figure 9 It is a plan view showing the inside of the display device according to Embodiment 2 of the present invention. Figure 10 yes Figure 9 A cross-sectional view of the main part of the display device cut along line BB in .

[0094] Such as Figure 10It is shown that, in the display device 2B of this embodiment, the heat insulating plate 46 is interposed between both ends of the heat sink 30B and the outline region 20 of the rear frame 12B. The heat insulating plate 46 blocks heat transfer from both ends of the heat sink 30B to the outer shell region 20 of the rear frame 12B. Accordingly, it is possible to more effectively suppress the temperature rise of the rear frame 12B of the outer frame region 20 exposed to the outside of the display device 2B.

[0095] Furthermore, if Figure 9 It is shown that, i...

Abstract

The present invention provides a display device capable of suppressing a temperature rise in a region of a rear frame exposed to the outside. The display device (2) for displaying images includes: a liquid crystal screen (6), displaying images; a backlight (8), illuminating light to the back of the liquid crystal screen (6); a rear frame (12), through screws (40) to support the backlight (8); and the back cover (16), covering a part of the side of the rear frame (12) that is different from the side configured with the backlight (8), the backlight (8), extending to the backlight (8) from the back cover ( 16) Outside the inner contour area (22) of the rear frame (12) covered, the screws (40) are only arranged in the inner contour area (22) of the rear frame (12) covered by the back cover (16).

Description

technical field [0001] The present invention relates to a display device for displaying images. Background technique [0002] Conventionally, a display device including a direct-type backlight for irradiating light to the back of a display screen, such as a liquid crystal television receiver, has been used (for example, refer to Patent Document 1). The casing of the display device is composed of a resin front case provided on the display side, and a resin rear case provided on the backlight side. Furthermore, a rear frame for supporting the backlight in a heat-conductive manner is provided between the front case and the rear case. The backlight includes a heat sink, a wiring board mounted on the heat sink, and a plurality of LEDs (Light Emitting Diodes) mounted on the wiring board. The radiator is connected to the rear frame by multiple screws. [0003] The rear frame, the heat sink, and the wiring board are each formed of a highly thermally conductive metal (for example,...
