ABSTRACT:
Provided is a liquid crystal panel that limits a viewing angle. The liquid crystal panel includes a plurality of color pixels and a plurality of interference sub-pixels. Each of the color pixels includes red (R), green (G) and blue (B) sub-pixels. The interference sub-pixels are included in each of the color pixels and disposed on the same plane as the color pixels to control light that penetrates the liquid crystal panel and travels in side directions of the liquid crystal panel, except the front direction thereof. The viewing angle can be controlled by the interference sub-pixels. Since the interference sub-pixels and the color sub-pixels are disposed on the same plane, the thickness and weight of the liquid crystal panel do not increase. Further, it is possible to prevent the decrease of the light quantity and the degradation of the brightness.
