LIGHT REFLECTOR, PLANAR LIGHT SOURCE AND ILLUMINATION DEVICE USING THE SAME

摘要

A light reflector comprising a resin film having a reflection angle peak ratio [i.e. (reflection peak value when a light ray is applied at an angle of 45° to the perpendicular line of the reflection surface) / (reflection peak value when a light ray is applied at an angle of 15° to the perpendicular line of the reflection surface)] of from 1. 3 to 10, and a specular reflectance [i.e. (reflectance) - (diffuse reflectance)] of from 1.4% to 10%. This light reflector can prevent generation of a bright line even when it is used in an illumination device having a plurality of light sources.
