Abstract
The present invention discloses a polarizing layer of a liquid crystal panel and manufacturing method thereof. A polarized ultraviolet (UV) light is irradiated on a UV reactive liquid crystal layer to form a polarized UV reactive liquid crystal layer having polarization properties, and it is used as the polarizing layer of the liquid crystal panel. The present invention has advantages of being thin in the thickness thereof, in addition to having high temperature resistance, as well as a simple manufacturing process, thereby reducing production costs.
