Light diffusing film, polarizing plate, image display device and production method of light diffusing film

摘要

A light diffusing film contains a thermoplastic resin as the main component and containing, in the thermoplastic resin, (A) a light-transmitting particle having an average primary particle diameter of 1 to 10 μm, wherein there is substantially no refractive index difference between the thermoplastic resin and the light-transmitting particle, wherein one surface has concavoconvex shape, the total haze value is from 5 to 40%, and the average film thickness is from 20 to 200 μm.
