Abstract: Disclosed is a liquid crystal display. The liquid crystal display comprises a first polarizer, a liquid crystal layer and a second polarizer. The liquid crystal layer is disposed between the first polarizer and the second polarizer. The present invention solves the problem that the dark-state light leakage is serious in the area near the horizontal viewing angle in the conventional liquid crystal display with a single-layer biaxial compensation architecture by adjusting compensation values of a biaxial layer of the first polarizer and a compensation value of a TAC layer of the second polarizer.
