Abstract: 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.
