Abstract:
1. A liquid crystal display device, comprising: a liquid crystal display panel; a first polarizer on a first surface of the liquid crystal display panel; a second polarizer on a second surface of the liquid crystal display panel; a first light path control film entirely formed on a first surface of the second polarizer to refract the light polarized by the second polarizer to only a lower direction at an outside of a display surface of the liquid crystal display panel in order to minimize a gray inversion on the display surface of the liquid crystal display panel; and a second light path control film on a first surface of the first polarizer to refract the light incident to the liquid crystal display panel, wherein each of the first and second light path control films includes a first base material and a second base material formed in a same layer and alternately deposited in a slanting line direction, and a refractive index of the first base material is different from that of the second base material, and wherein each of the first and second base materials includes at least one of PMMA, PET system, PS system, and PP system resin.
