发明名称 Liquid crystal display with two positive tilted retardation films and two negative retardant films
摘要 A liquid crystal display includes a tilted retarder. The tilted retarder has an optical axis which is aligned at an angle of from about 5 DEG to 15 DEG with respect to normal. Thus, because the optical axis of the liquid crystal layer is aligned at an angle to one side of normal and the optical axis of the tilted retarder(s) is at an angle to the other side of normal, the retardation effects substantially cancel one another out. Tilted retarder(s) may be used in combination with negatively birefringent retarders according to certain embodiments of this invention in twisted nematic normally white displays.
