Filed: 1989-11-15
Abstract: PURPOSE:To obtain a reflection type screen where brightness is uniform all over the surface by inclining the respective directions of respective reflecting plane elements in the normal direction of the center part of the surface of the reflection type screen. CONSTITUTION:The directions of the reflecting plane elements are respectively inclined in the normal direction of the center part of the surface of the reflection type screen 11. Since reflected light 7 from a peripheral part is inclined in the direction of center axis of the screen 11 and reflected, in such a case, a viewer existing in front of the screen does not feel that the peripheral part of the screen 11 is dark. Furthermore, the reflected light 7 is allowed to the within an angle formed by the projected light 6 with the normal direction of the center part of the screen 11 so that the light may be reflected most toward the viewer, because the viewer generally views the screen in the rear of a projector 1. Thus, the reflected light quantity on the peripheral part of the screen 11 is prevented from being relatively lowered and the brightness is made uniform all over the surface of the screen 11.
