Abstract
Disclosed is a liquid crystal display device having a wide viewing angle, in which compensation films are disposed between a liquid crystal display panel and polarizers to change a polarized state of light, which is incident on the liquid crystal display panel and output therefrom through the polarizers, thereby preventing light from being leaked in a diagonal direction of the liquid crystal display device in a normally black mode.
