Transparent support, optical film, polarizing plate and image display device

摘要

Provided is a transparent support including a light-transmitting particle having an average particle diameter of 6 to 20 µm, wherein the transparent support has a thickness of from 20 to 200 µm, the light-transmitting particle is contained in a ratio of 0.5 to 20 mass% based on entire solid content in the transparent support, and the transparent support has an arithmetic average roughness (Ra) of 0.05 µm or less.
