LIGHT REFLECTOR AND SURFACE LIGHT SOURCE DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a light reflector which has a high reflectance and is capable of improving luminance even in a direct backlight. SOLUTION: The light reflector has a variable angle reflectance R1 of 90-120% when a beam irradiation angle is 15°and a light receiving angle is 0°, and a variable angle reflectance R2 of 85-110% when a beam irradiation angle is 75°and a light receiving angle is 0°.
