发明名称 Display device, electronic apparatus and lighting device
摘要 In a lighting device of a display device, a plurality of light emitting elements are mounted on a surface of a light source substrate, and the light source substrate is supported by a light source support member by means of a positioning (fixing) structure such as a metal screw. The plurality of light emitting elements are divided into a plurality of blocks, and the emission light amount can be controlled with respect to each of the blocks. Although the head of the screw is exposed on the surface of the light source substrate, the screw is located between adjacent ones of the blocks. Therefore, even though the illuminating light intensity becomes partially discontinuous owing to the presence of the screw, degradation of display quality originating from such discontinuity can be suppressed.

主权项 1. A display device, comprising: a lighting device; and a display panel disposed to overlap a light-emitting surface of the lighting device, wherein the lighting device includes: a light guide plate disposed to overlap the display panel; a plurality of light emitting elements aligned along a first side of the light guide plate in a direction from an end portion toward the other end portion thereof, with a light-emitting surface of each of the plurality of light emitting elements arranged so as to oppose the first side, the first side serving as a light-receiving surface; a light source driver that controls the plurality of light-emitting elements with respect to each of a plurality of blocks of the light-emitting elements; a light source substrate having the plurality of light emitting elements mounted on a first surface thereof; a light source support member attached to a second surface of the light source substrate; and a positioning structure located between adjacent ones of the plurality of blocks so as to place the light source substrate in position on the light source support member, with at least a part of the positioning structure exposed on the first surface of the light source substrate, wherein the plurality of light emitting elements are divided into a plurality of blocks in the direction from an end portion toward the other end portion of the first side, and the light source driver controls an amount of light to be emitted from each of the blocks, in accordance with a mode in which the display panel is driven.
