Problems solved by technology

[0011] However, as described above, considering the expansion of the light guide plate, etc., a predetermined air gap is formed between the incident surface of the light guide plate and the light source, and accordingly there is a problem that the distance between the incident surface of the light guide plate and the light source is too large. Long, resulting in low incidence efficiency of the light emitted from the light source to the incident surface, and low efficiency of light use

Abstract

A display device includes: a casing configured by at least one chassis; a display arranged inside the casing; a light guiding plate arranged on a rear face side of the display and has an outer peripheral face at least a part of which is formed as an incident face on which light is incident; a light source unit including a light source arranged to face the incident face of the light guiding plate on a lateral side of the light guiding plate; and a heat dissipating member, to which the light source unit is attached, that dissipates heat generated when the light source is driven. The heat dissipating member or the light source unit is attached to the light guiding plate, and the heat dissipating member and the light source unit can be moved with respect to the chassis in accordance with expansion or shrinkage of the light guiding plate.

Description

technical field [0001] The present technology relates to the technical field of display devices. More specifically, it relates to the technical field of improving the use efficiency of light emitted from a light source by attaching a heat dissipation member or a light source unit to a light guide plate. Background technique [0002] Liquid crystal panels are used, for example, in display devices such as televisions and personal computers used to display images. The display is disposed within a housing constructed from a plurality of cabinets. [0003] Since the liquid crystal panel is not a self-luminous type display, the above-described display device is configured such that light as a back light is emitted toward the liquid crystal panel from the rear side. Therefore, in each display device having a display that is not a self-luminous type such as a liquid crystal display, a light source unit having a light source serving as a backlight that radiates light toward the dis...
