<P>PROBLEM TO BE SOLVED: To realize a screen having a projection surface hardly influenced by external light and having a large gain, and a projection surface having a wide visual angle and natural feeling. <P>SOLUTION: The screen is equipped with a light reflection layer between a directional diffusing layer diffusing and transmitting light from a prescribed direction and linearly transmitting light from other directions, and an isotropic light diffusing layer nearly isotropically diffusing light regardless of an incident angle. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
