Abstract
The present invention provides a bright light transmission screen and light diffusion panel. Am amtireflective film is disposed on the surface of a lenticular lens sheet substrate included in a light transmission screen. The antireflective film is made from a high polymer compound of a low refractory index and has a thickness that is different from .lambda./(4n). The antireflective film may also be disposed on a Fresnel lens sheet substrate or a light diffusion panel substrate.
