REFLECTIVE SCREEN, FRONT PROJECTION DISPLAY DEVICE, AND MULTI-SCREEN DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reflective screen which utilizes light highly efficiently to allow display of a bright and satisfactory image, and a front projection display device and a multi-screen display device including the same.SOLUTION: A reflective screen 10 comprises a lens layer 12 in which a plurality of unit lenses 121 formed like a substantially triangular prism which is convex to the rear side are arrayed, and a reflection layer 13 formed on two slopes 121a and 121b of each unit lens 121. In a region A which is a part of the lens layer 12 in an array direction of the unit lenses 121, image light L1 projected from one side and image light L2 projected from the other side impinge on different slopes of the same unit lens 121, are reflected by the reflection layer 13, and are emitted in the same direction substantially. In regions B1 and B2 other than the region A, image light impinges on only one slope out of two slopes of the unit lens 121 but does not impinge on the other slope.
