Abstract

A liquid crystal display panel is provided, which includes a color filter substrate including an array of red, green, blue, and white color resistances. An array substrate disposed opposite to the color film substrate. The array substrate includes a plurality of data lines and a plurality of gate lines vertically arranged, the data lines and the gate lines divide the array substrate into a plurality of sub-pixel areas. A liquid crystal layer disposed between the array substrate and the color filter substrate. The white sub-pixel area is provided with a heating layer for heating the liquid crystal layer, which solves the problem that the liquid crystal display panel exhibits undesirable phenomena such as smear due to abnormal liquid crystal state when operating in a low-temperature environment.
