Abstract

PURPOSE:To obtain a reflective screen which can be easily viewed from any direction with a large reflection factor and no directivity, by forming a metallic film vapor-deposited on the surface of a substrate having a specific space factor. CONSTITUTION:A substrate 1 is made of a plastic film having 10-40% space factor (SF) which is shown by an equation, where dm is the thickness of the substrate measured by a micrometer (thickness at the projected part) and dw is the thickness of the substrate obtained from the weight through conversion. Such substrate is fixed on a fixed plate 4. Then a metallic vapor-deposited film 2 made of Al, Cr, etc. plus a protecting film 3 made of a thin film of polymethacrylate, etc. having high light transmittance are provided on the substrate 1. Thus the intensity of the reflected light is increased for a new reflective screen by 1.3-1.5 times as much as that of a conventional screen.
