Abstract
A light source device includes a circuit board having a LED mounted on a surface, a lens attached to the surface so as to diffuse light emitted from the LED, a reflecting sheet having a through hole in the inside of which the lens is disposed and reflecting light emitted from the LED at an opposite side of the surface, and a restricting member which is disposed at one of an edge of the through hole in the reflecting sheet and the lens, and restricts a deviation of the reflecting sheet in a direction departing from the surface.
