An optical sheet and a light transmission screen using the same

摘要

The present invention provides a bright light transmission screen and light diffusion panel. An antireflective film (5) is disposed on the surface of a lenticular lens sheet substrate (7) included in a light transmission screen. The antireflective film (5) 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 (55) substrate or a light diffusion panel substrate.
