LIGHT SOURCE DEVICE, DISPLAY DEVICE, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To realize functions equivalent to those of a parallax barrier using a light guide plate and provide illumination light of a desired luminance distribution.

SOLUTION: A light source device includes: a first light source for emitting first illumination light; a light guide plate including a plurality of scattering areas each allowing the first illumination light that has entered the light guide plate from a side direction to be scattered in the plurality of scattering areas and exit to the outside. A light scattering characteristic is added to the scattering areas by forming a plurality of depression and projection shapes in surfaces of the scattering areas or dispersing a light scattering material in the scattering areas, and density of the depression and projection shapes or concentration of the light scattering material in the scattering areas changes according to position.
