Abstract
A light source device which includes a light source, a diffusion member configured to diffuse light from the light source, a reflection sheet configured to reflect the light from the light source to the diffusion member, a storage housing in which the diffusion member and the reflection sheet are stored to face each other, and positioning parts configured to position the diffusion member and the reflection sheet in the storage housing is provided. And the reflection sheet is provided with convex parts in one edge part thereof at positions corresponding, in a facing direction, to notches of the diffusion member which correspond to the positioning parts, such that light reflectance in the vicinity of the notches of the diffusion member is increased.
Claims18
A light source device which includes a light source, a diffusion member configured to diffuse light from the light source, a reflection sheet configured to reflect the light from the light source to the diffusion member, a storage housing in which the diffusion member and the reflection sheet are stored to face each other, and positioning parts which are provided in the storage housing and position the diffusion member and the reflection sheet in the storage housing,
- wherein
- the diffusion member is provided with notches corresponding to the positioning parts in one side surface part thereof,
- the reflection sheet has a flat surface facing the diffusion member, and concaves and convexes which are protruding and recessed along the flat surface in one edge part of the flat surface corresponding to the one side surface part of the diffusion member, and
- the notches of the diffusion member are disposed to correspond to convex parts of the one edge part of the reflection sheet in the facing direction in which the diffusion member and the reflection sheet face each other.
