Abstract:
1. A liquid crystal display comprising: a liquid crystal panel assembly including two panels and a liquid crystal layer interposed between the panels and having first and second outer surfaces opposite each other; first and second polarizers on the first and the second surfaces of the panel assembly, respectively; a first a-plate film with reverse wavelength dispersion that birefringence increases as a wavelength of incident light increases, and is inserted between the first polarizer and the first surface of the panel assembly; a first hybrid c-plate compensation film inserted between the first a-plate film and the first polarizer; a second a-plate film with reverse wavelength dispersion inserted between the second polarizer and the second surface of the panel assembly; and a second hybrid c-plate compensation film between the second a-plate film and the second polarizer, wherein a retardation value of the first a-plate film ranges about 5 nm through about 45 nm for a light wavelength of about 550 nm, about (0.4-0.7)*(the retardation value for the light wavelength of about 550 nm) for a light wavelength of about 400 nm, and about (1.1-1.4)*(the retardation value for the light wavelength of about 550 nm) for a light wavelength of about 650 nm.
