Abstract
A liquid crystal display and an optical compensation method therefor are provided specifically for adjusting compensation values of an uniaxial positive birefringence A-compensation film (A-Plate) and an uniaxial negative birefringence C-compensation film (C-Plate) and particularly for controlling a valuing range of a compensation value (R) of the C-Plate, so as to reduce the dark-state light leakage by adjusting the compensation values of two types of the compensation film. Thus, the present invention can reduce the dark-state light leakage of a large viewing angle and increase the contrast and definition of the large viewing angle.
