Abstract
A reflection type screen having a high SG value, a wide view angle and an excellent color reproducibility of bright parts of projected image is provided. The reflection type screen comprises a substrate having a light reflecting property such as a white plastic film and a light diffusion layer 2 formed on the substrate, which contains a light diffusion agent and a pearl pigment dispersed in a binder resin. The pearl pigment is mica covered with titanium dioxide and has an optical characteristic reflecting blue component of light projected by a projector and transmitting light of a color complementary to blue. When PC images having many white parts or the like are projected on the screen, the bright part of the images does not become yellowish and projected images with high whiteness can be obtained. The content of pearl pigment is preferably 5-100 parts by weight based on 100 parts by weight of the binder resin and 10-150 parts by weight based on 100 parts by weight of the light diffusion agent.
