White reflective film for direct surface light source and direct surface light source using the same

摘要

A reflection film having a reflection layer A and a surface layer B containing particles mainly composed of a resin, and the surface layer B has a glossiness of 3 or more and less than 16 at an incident angle of 85 degrees, Furthermore, the white reflective film for direct type | mold surface light sources which has a light source provided with the lens cap whose glossiness of 60 degrees of incident angles is 17 or more and less than 50. When this film is used for a direct type surface light source having a light source provided with a lens cap (particularly, a reflective lens cap) as a light source, it is possible to suitably suppress luminance unevenness.
