Abstract:
1. A liquid crystal display (LCD), comprising a backlight source for generating light, and the LCD also comprising a first triacetate cellulose (TAC) film; a first polyvinyl alcohol (PVA) film; a first phase compensator film, for providing a first retardation value and a second retardation value by adjusting thickness of the first phase compensator film and by adjusting a first refractive index, a second refractive index, and a third refractive index corresponding to the light in a first direction, the light in a second direction, and the light in a third direction, respectively; a liquid crystal (LC) cell; a second phase compensator film, for providing a third retardation value by adjusting thickness of the second phase compensator film and by adjusting a fourth refractive index, a fifth refractive index, and a sixth refractive index, respectively; a second PVA film; and a third TAC film; wherein black-state light leakage at a wide viewing angle is controlled according to the first retardation value, the second retardation value, and the third retardation value in the LCD, wherein the third retardation value is determined by the fourth refractive index, the fifth refractive index, the sixth refractive index, and thickness of the second phase compensator film, and the third retardation value is between Y
