Abstract
The present invention discloses a liquid crystal display and a method of optical compensation thereof. Specifically, the present invention adjusts compensation values of a uniaxial positive birefringence A-Plate and a uniaxial negative birefringence C-Plate, especially a value range of retardation in a thickness direction Rth of the uniaxial negative birefringence C-Plate is controlled. By adjusting the compensation values of the above-mentioned two types of compensation films, the dark-state light leakage phenomenon is suppressed. The present invention is capable of suppressing the dark-state light leakage phenomenon at a large viewing angle effectively and increasing the contrast and clarity at a large viewing angle.
