发明名称 BACK FACE TRANSMISSION SCREEN
摘要 A rear-projection screen is formed by adhesively bonding a front transparent sheet (2f) to the front surface of a transparent plate (3) on a viewing side (A), and adhesively bonding a wide-angle diffusing sheet (2r) to the rear surface of the transparent plate (3) on an image-projecting side. The front transparent sheet (2f) is provided in its front surface with a plurality of horizontal, parallel, minute ridges (4) having a triangular cross section. A side surface facing up or down of the two side surfaces of each minute ridge (4) is coated with a shading film (5), and the other side surface is transparent. The surface on the viewing side of the rear-projection screen does not reflect images even in a bright environment and are capable of displaying high-definition images having a high black level. The rear-projection screen can be used for forming a large screen. <IMAGE>
