New optical sheet and liquid crystal display device using same sheet

摘要: PURPOSE: To obtain an excellent phase difference compensation film for the liquid crystal display device by setting mean orienting direction of high molecular chains a transparent synthetic resin sheet at certain angle to surface direction. CONSTITUTION: The constituting 3 is as shown 4 and slants α° A retardation value from 5 perpendicular R values slanting directions 6 7 θ vertical are all mutually different. This used LCD which uses, example, STN eliminate between images seen when viewed directly front slantingly, consequently reduction coloring display, improvement contrast ratio, etc., realized.
