Patent ID: 7292297

Claim:
An optical film assembly for a liquid crystal display panel including a liquid crystal layer having a twist angle of about −10 degree to about +10 degree, the optical film assembly comprising: a lower polarizer disposed under a lower substrate of the liquid crystal display panel, the lower polarizer including an absorption axis forming at an angle of about 122 degree to about 142 degree in a clockwise direction with respect to a major axis of a liquid crystal of the liquid crystal layer, and the liquid crystal being disposed adjacent to the lower substrate; a lower λ/2 retardation film disposed between the lower substrate and the lower polarizer, the lower λ/2 retardation film including a first optical characteristics Δnd 1 of about 260 nm to about 280 nm, a slow axis of the lower λ/2 retardation film forming at an angle of about 95 degree to about 115 degree in the clockwise direction with respect to the absorption axis; and a lower λ/4 retardation film disposed between the lower substrate and the lower λ/2 retardation film, the lower λ/4 retardation film including a second optical characteristics Δnd 2 of about 120 nm to about 140 nm, a slow axis of the lower λ/4 retardation film forming at an angle of about 161 degree to about 181 degree in the clockwise direction with respect to the absorption axis, wherein ‘Δn’, ‘d 1 ’ and ‘d 2 ’ denote an anisotropy of a refractive index, a thickness of the lower λ/2 retardation film and a thickness of the lower λ/4 retardation film, respectively.
