Abstract
The present invention provides a light source device which includes light emitting elements mounted on one surface of a substrate, and a reflection sheet provided on the one surface of the substrate to reflect light from the light emitting elements toward a region opposed to the one surface, prevents the reflection sheet from floating from the one surface of the substrate, and reduces regions lacking the reflection sheet in the vicinity of the diffusion parts, as well as, suppress an occurrence of luminance unevenness caused by the floating of the reflection sheet and the lacking of the reflection sheet, and a display apparatus including the light source device. The light source device includes a diffusion part which are provided proximal to a light emission surface of the light emitting element to diffuse the light from the light emitting element, and the reflection sheet is configured so as to have through holes including a part in which a distance between two opposite points in edge thereof is not more than a size of the diffusion part in a view along a vertical direction to the one surface, and the through hole is formed at a position matching with that of the diffusion part in a view along the vertical direction to the one surface.
