Title:
PROJECTION SCREEN
Document Type and Number:
WIPO Patent Application WO/2023/074890
Kind Code:
A1
Abstract:
A projection screen 1 is used by being attached to an optically transparent adherend, and is provided with a transparent base material 11 and an adhesive agent layer 12. A 0°-frontal luminance on the transparent base material 11 side as measured using transmitted light from a white light source of 1100 cd/m2 is 10-400 cd/m2 , and the luminance ratio of a 45°-diagonal luminance on the transparent base material 11 side as measured using transmitted light from a white light source of 1100 cd/m2 with respect to said 0°-frontal luminance is 0.5 or more. By using the projection screen 1, it is possible to achieve both background visibility when the projector is turned off and diagonal visibility and frontal visibility when the projector is turned on.
