However, if this configuration is adopted, the heat generated on the light source substrate will be concentrated near the surface of the holder plate and will not be easily dispersed to other parts. Therefore, the temperature of the part that contacts the surface of the holder plate in the cover part that becomes the accessible part may be lower than that of the heat source board. rise locally

Embodiment approach 1

[0051] refer to Figure 1 to Figure 9Embodiment 1 will be described. In this embodiment, a liquid crystal display device (an example of a display device) 10 is illustrated. In addition, an X axis, a Y axis, and a Z axis are shown in a part of each drawing, and each axis direction is described as a common direction in each drawing. Wherein, the Y-axis direction is consistent with the vertical direction, and the X-axis direction is consistent with the horizontal direction. In addition, descriptions of up and down are based on the vertical direction unless otherwise specified.

[0052] The television receiver TV includes: a liquid crystal display unit LDU; various substrates PWB, MB, and CTB installed on the back side (back side) of the liquid crystal display unit LDU; , the cover member CV installed in the manner of CTB; and the base ST, which keeps the display surface of the liquid crystal display unit LDU in a state along the vertical direction (Y-axis direction) by the bas...

Embodiment approach 2

[0093] Embodiment 2 will be described with reference to the drawings. The shape of the substrate mounting portion 119 of the second embodiment is different from that of the first embodiment. The other configurations are the same as those of Embodiment 1, and thus descriptions of the configurations, operations, and effects are omitted. In addition, in Figure 10 respectively Figure 7 The portions where the numeral 100 is added to the reference numerals are the same as those described in the first embodiment.

[0094] In the liquid crystal display device 110 of Embodiment 2, as Figure 7 As shown, the bottom surface portion 119 b of the board mounting portion 119 is configured to extend outward compared with the first embodiment. Specifically, the plate surface on the front side of the bottom surface 119b, that is, the plate surface on the opposite side to the surface in contact with the base 114, is formed to face the screw mounting portion 121 of the frame 113, and extend...

Embodiment approach 3

[0096] Embodiment 3 will be described with reference to the drawings. Embodiment 3 differs from Embodiment 1 in the shape of a part of panel holding portion 213 a in frame 213 . The other configurations are the same as those of Embodiment 1, and thus descriptions of the configurations, operations, and effects are omitted. In addition, in Figure 11 respectively Figure 7 The portions where the numeral 200 is added to the reference numerals are the same as those described in the first embodiment.

[0097]In the liquid crystal display device 210 of Embodiment 3, as Figure 11 As shown, the panel pressing portion 213a of the frame 213 is provided with a cutout 213s, so that a part of the panel pressing portion 213a of the frame 213 facing the printed circuit board 227 is located lower than the pressing protrusion 224 of the frame 213 (the part that contacts the liquid crystal panel 211). The position on the front side (the side opposite to the base 214). Furthermore, the fle...

Abstract

A liquid crystal display device (10) is provided with: an LED (17); a liquid crystal panel (11); a light guide plate (16); a chassis (14) that is arranged on the side opposite to the liquid crystal panel (11) side with respect to the light guide plate (16); a frame (13) which is arranged on the display surface side with respect to the liquid crystal panel (11) and is in contact with the chassis (14) in such a manner that the liquid crystal panel (11), the LED (17) and the light guide plate (16) are sandwiched and contained between the frame (13) and the chassis (14); a substrate mounting part (19) that is fitted onto the chassis (14) so as to be apart from the frame (13); an LED substrate (18) which is in contact with the substrate mounting part (19) and on the surface of which the LED (17) is arranged; and holding members (31, 32) which hold the LED substrate (18) with respect to the substrate mounting part (19) by sandwiching the substrate mounting part (19) and the LED substrate (18) therebetween.

Description

technical field [0001] The present invention relates to a display device and a television receiver. Background technique [0002] In recent years, the display elements of image display devices represented by television receivers have been continuously developed from conventional Braun tubes to thin display devices using thin display elements such as liquid crystal panels and plasma display panels, which can realize the thinning of image display devices . The liquid crystal panel used in the liquid crystal display device does not emit light itself, so a backlight device is additionally required as an illumination device. [0003] The backlight device generates heat on the light source substrate on which the light source is mounted as the light source emits light. Therefore, it is required to efficiently dissipate the heat generated on the light source substrate to the outside of the backlight device. For example, Patent Document 1 discloses an edge-light type backlight uni...
