Patent ID: 8408774

Claim:
A light reflector comprising: a resin film, wherein the resin film comprises a bright line preventing layer (B), the bright line preventing layer (B) contains a filler in a concentration of at most 20% by weight, the light reflector has a reflection angle peak ratio P of from 1.3 to 10, in which the reflection angle peak ratio P is obtained from a reflection peak value P 1 and a reflection peak value P 2 , as measured on a surface of the bright line preventing layer (B), according to the formula (1): Reflection Angle Peak Ratio P=P 2 /P 1 (1) wherein P 1 represents a reflection peak value of the light reflector when a light ray is applied at an angle of 15° to a perpendicular line of the surface of the bright line preventing layer (B) of the light reflector; P 2 represents a reflection peak value of the light reflector when a light ray is applied at an angle of 45° to the perpendicular line of the surface of the bright line preventing layer (B) of the light reflector, the light reflector has a specular reflectance R 2 of from 1.4% to 10%, in which the specular reflectance R 2 is obtained from a reflectance R 1 and a diffuse reflectance R 3 , as measured on the surface of the bright line preventing layer (B), according to formula (2): Specular Reflectance R 2 =R 1 −R 3 (2) wherein R 1 represents a reflectance on the surface of the bright line preventing layer (B) of the light reflector; R 3 represents a diffuse reflectance on the surface of the bright line preventing layer (B) of the light reflector, the surface of the bright line preventing layer (B) has projections and recesses, and a density by number of the projections and recesses of the surface of the bright line preventing layer (B) is from 0.1×10 −4 to 3.5×10 −4/μm 2 .
