Liquid crystal display

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 corresponding to the light in the first direction, the light in the second direction, and the light in the third direction, 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.
