Abstract
Disclosed is a liquid crystal display device capable of improving a viewing angle thereof while reducing a gray scale inversion. The liquid crystal display device has a porous film aligned on a liquid crystal display panel and having a plurality of pores. The porous film has sidewalls defined by the pores and reflecting a part of light exited from the liquid crystal display panel. That is, the sidewalls reflect a first group of light, which has relatively higher luminance by passing through a short axis of liquid crystal, towards a second group of light having a relatively lower luminance by passing through a long axis of liquid crystal. Accordingly, the viewing angle of the liquid crystal display device is expanded and the gray scale inversion is reduced.
