摘要:
There is provided a light diffusion film in which a decrease in the half-value angle can be suppressed even after processing with a high elongation rate. A light diffusion film including a base material film and a light diffusing layer, the light diffusing layer containing light diffusing particles and a resin binder, wherein a ratio (T/t) of an average film thickness T of the light diffusing layer, to an average particle diameter t of the light diffusing particles, is 3.0 or more.
