Compensation System for Liquid Crystal Panel and Liquid Crystal Display Device

摘要

The present invention provides a compensation system for liquid crystal panel and liquid crystal display device. The compensation system includes first biaxial compensation film and second biaxial compensation film, disposed on two sides of liquid crystal panel respectively, first biaxial compensation film having planar compensation value Ro1 for incident light of 550 nm wavelength and compensation value Rth1 along thickness direction, second biaxial compensation film having planar compensation value Ro2 for incident light of 550 nm wavelength and compensation value Rth2 along thickness direction; wherein 15 nm≦Ro1≦94 nm; 35 nm≦Rth1≦214 nm; 35 nm≦Rth1≦214 nm; 14 nm≦Ro2≦101 nm; Y1≦Rth2≦Y2; Y1=0.004302×Rth12−1.96894×Rth1+259.7; Y2=−0.00234308×Rth12−0.32227×Rth1+245. As such, the present invention effectively reduces dark state light leakage of liquid crystal panel by disposing biaxial compensation films of appropriate compensation values.
