摘要: A holographic screen of a rear projection type for use in projector transmitting light received from end the onto viewing surface. The includes sheet including surface forming into an image viewing, plurality diffusion protrusions disposed on predetermined intervals along horizontal and vertical directions diffusing incident light, scattering formed over entire absorbers between protrusions, absorbing ambient to Thus, with improved contrast is displayed screen.
