TRANSMISSIVE SCREEN

WIPO Patent Application WO/2022/154060

A1

A screen (25) is provided with a back surface-side first layer (37) and a front surface-side second layer (38). The first layer (37) is provided with an array of lens bodies (31) facing the front surface side of the screen (25). Each lens body (31) has an asymmetric structure in which a high diffusion surface (33) formed by a lens curved surface and a low diffusion surface (36) having a smaller curvature than the lens curved surface are placed back to back. At least on the high diffusion surface (33), a reflection film (Rf) that transmits a part of incident light and reflects a part thereof is formed. The second layer (38) is provided with an inversely shaped array that covers the lens bodies (31) while facing the back surface side of the screen (25). Image light (Im) obliquely projected from the back surface side of the screen (25) is refracted by an interface on the back surface side of the first layer (37), further reflected by the high diffusion surface (33), and further refracted by an interface on the front surface side of the second layer (38) and emitted toward the front surface side of the screen (25).
