Abstract
A polarizer plate including a polarizer substrate formed of a polarizer layer and supporting layers disposed on opposite surfaces of the polarizer layer; an undercoat layer disposed on one surface of the polarizer substrate; an anti-reflection layer disposed on the undercoat layer; and an anti-staining layer including a fluorine-containing silane compound disposed on said anti-reflection layer. The undercoat layer preferably has a specular glossiness according to JIS Z 8741 of from 10 to 40 and a haze according to JIS K 6900 of from 5 to 30%.
