Abstract
An anti-reflection plate for a display device, including a transparent substrate wherein, on one or both surfaces of the substrate, a flat first layer consisting of a transparent hardening agent containing a silicon-containing organic compound has been applied and dried and, on the first layer, a second layer consisting of a transparent hardening agent containing a silicon-containing compound has been spray coated and hardened to form an uneven surface having projections each having a height of 0.1 to 2.0 .mu.m in height, a diameter of 10 to 100 .mu.m and a height/diameter ratio of 1/30 to 1/500 can effectively prevent reflection of external light on a screen of a display device without deteriorating the resolution of an image on the screen.
