Liquid crystal display device using a phase-difference film and in-plane switching mode liquid crystal display device using a phase-difference film
Abstract:
A liquid crystal display (LCD) device is provided. The LCD device includes an LCD panel having a first liquid crystal layer therein; a first polarizing sheet; and a first phase-difference compensation portion disposed adjacent a first surface of the LCD panel between the LCD panel and the first polarizing sheet. The first phase-difference compensation portion includes a plurality of phase-difference films having at least second and third liquid crystal layers with tilt angles that are different.
