A liquid crystal display and an optical compensation method thereof. Specifically, compensation values of a positive dual twisted single axis A-compensation film (36) and a negative dual twisted single axis C-compensation film (37) are changed, and especially, the value range of the compensation value Rth of the negative dual twisted single axis C-compensation film (37) is controlled. The dark-state light leak phenomenon is weakened by adjusting the compensation values of the foregoing two compensation films, which can effectively weaken the dark-state light leak phenomenon at a large viewing angle, and increase the contrast and the sharpness at the large viewing angle. |
