Abstract:
1. An optical film assembly for a liquid crystal display panel including a liquid crystal layer having a viewing angle of about 170 degree to about 250 degree in a clock direction with respect to a horizontal direction of the liquid crystal display panel and 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 8 degree to about 28 degree in a clockwise direction with respect to the horizontal direction of the liquid crystal display panel; a lower λ/2 retardation film disposed between the lower substrate and the lower polarizer, the lower λ/2retardation film including a first optical characteristics Δnd 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 wherein ‘Δn’, ‘d
