Liquid crystal display device with wide-viewing angle

摘要

An LCD device includes a liquid crystal panel; a first polarizer attached to a first surface of the liquid crystal panel and including a first polarizing film, first and second optical compensation films disposed on one surface of the first polarizing film, and a phase retardation film, a protective film and a functional film disposed on another surface of the first polarizing film; and a second polarizer attached to a second surface of the liquid crystal panel and including a second polarizing film, an inner protective film disposed on one surface of the second polarizing film, and an outer protective film disposed on another surface of the second polarizing film, wherein the first polarizing film is disposed between the phase retardation film and the liquid crystal panel, and the phase retardation film has a retardation value of λ/4.

主权项

1. A liquid crystal display device, comprising:
a liquid crystal panel; a first polarizer attached to a first surface of the liquid crystal panel and including a first polarizing film, first and second optical compensation films, a phase retardation film, a protective film, and a functional film providing at least one of a hard-coating function and an anti-static function, wherein the first and second optical compensation films are disposed on one surface of the first polarizing film, and the phase retardation film, the protective film and the functional film are disposed on another surface of the first polarizing film; and a second polarizer attached to a second surface of the liquid crystal panel and including a second polarizing film, an inner protective film, and an outer protective film, wherein the inner protective film is disposed on one surface of the second polarizing film, and the outer protective film is disposed on another surface of the second polarizing film, wherein the first polarizing film is disposed between the phase retardation film and the liquid crystal panel, and the phase retardation film has a retardation value of λ/4, wherein the first and second optical compensation films are disposed between the phase retardation film and the liquid crystal panel, and wherein the phase retardation film is configured to convert linearly polarized light received from the first polarizing film into circularly polarized light output by the liquid crystal display device.
