The present disclosure provides a LCD screen, including a liquid crystal panel, a first functional layer disposed on an array substrate of the liquid crystal panel, a quarter-wave plate and a polarizing layer sequentially stacked on the first functional layer, wherein the array substrate has a metal wire that reflects ambient light sequentially passing through the polarizing layer, the quarter-wave plate and the first functional layer and striking the surface of the metal wire; an included angle is between the optical axis of the quarter-wave plate and the absorption axis of the polarizing layer so as to block the ambient light reflected by the metal wire in the polarizing layer. The angle between the optical axis of the quarter-wave plate and the absorption axis of the polarizing layer of the present disclosure is 30-60°, so that the ambient light entering the polarizing layer is blocked in the polarizing layer.
