Abstract

PURPOSE:To ensure the directivity in both the horizontal and vertical directions for a reflective screen with the facilitated production, by providing the directivity to the reflective layer on the back of a lenticular plate. CONSTITUTION:A reflective layer 2 which is provided on the back of a lenticular plate 1 is made of a metallic thin plate of the aluminum foil, etc. The inner face of the layer 2 is made uneven to obtaifn the vertical directivity to the horizontal directivity of the plate 1. When the parallel light L is irradiated to a screen having such constitution, the vertical directivity (b) can be obtained by the layer 2 to the horizontal property (a) of the plate 1. In this case, no special process is applied to the plate 1 itself to facilitate easy production.
