Illumination device and liquid crystal display device |
摘要 |
An illumination device includes a light source and a planar illuminator for emitting light of the light source portion from one surface thereby to illuminate a liquid crystal panel. The planar illuminator has a reflection surface, on which minute concavo-convex shapes are substantially randomly formed. Surface emission is performed by diffuse reflecting the light irradiated from the light source portion by the reflection surface.
