Document Type and Number:
WIPO Patent Application WO/2016/006025
Kind Code:
A1
Abstract:
Provided are: a light source device that is equipped with a light-emitting element that is mounted to one surface of a substrate, and with a reflective sheet that is provided on said one surface and reflects light from the light-emitting element in a direction perpendicular to said one surface, said light source device preventing the reflective sheet from rising from said one surface of the substrate, reducing a region in which the reflective sheet is lacking near a diffusion portion, and suppressing the occurrence of luminance nonuniformity caused by the rising of the reflective sheet and the lack of the reflective sheet; and a display device. The invention is provided with a diffusion portion that is provided on a light output surface side of the light-emitting element and diffuses the light from the light-emitting element, and the reflective sheet is configured to have a through-hole including a portion in which the dimensions between opposing ends are equal to or smaller than the size of the diffusion portion in the aforementioned perpendicular direction, said through-hole being provided in a position that is aligned with the diffusion portion in said perpendicular direction.
