[0002] Liquid Crystal Display (LCD for short) is widely used in various fields due to its advantages of thinness, no radiation, and low power consumption; however, under extreme weather conditions, the use of traditional LCD may be affected, such as in extreme In cold or extremely hot environments, the LCD monitor may not display properly
[0003] The main reason for the above phenomenon is that the widest temperature at which liquid crystal materials can maintain their liquid crystal state at this stage is -40°C to 100°C, and the temperature that can be displayed is only at -20°C to 60°C
Liquid crystal materials are very sensitive to temperature changes. In low temperature environments, the response speed of liquid crystal materials slows down and the response time is greatly prolonged, which causes serious lag of the display screen.

Abstract

The embodiment of the invention provides a color film substrate, a liquid crystal display panel and a liquid crystal display device and relates to the technical field of display. Heat can be provided for the liquid crystal display panel in a low-temperature working state, so that the liquid crystal display panel can perform normal display. The color film substrate comprises a black matrix, a color filter layer and a heating layer which are all arranged on a substrate body, wherein the position of the heating layer corresponds to that of the black matrix, and the heating layer comprises a P-type semiconductor thermoelectric material area and an N-type semiconductor thermoelectric material area which make contact with each other. The color film substrate is used for manufacturing the display device.
