Uniform heating device applied to liquid crystal display and liquid crystal display

The invention discloses a uniform heating device applied to a liquid crystal display and the liquid crystal display. The uniform heating device comprises a first heating unit and a second heating unit. The first heating unit is fixed in a display area of a liquid crystal screen of the liquid crystal display. The second heating unit is fixed on the back surface of the liquid crystal screen. The heating surfaces of the first and second heating units face the liquid crystal screen. The first heating unit is a flexible resistive film which is shaped along the outer edge of the display area of the display screen. The second heating unit adopts indium tin oxide (ITO) transparent conductive glass for heating. The uniform heating device and the liquid crystal display have the advantages that a rational heating design is adopted, so that the shortcomings of display of the liquid crystal screen at low temperature can be overcome, the 6-minute overall performance display of the liquid crystal screen at -45 DEG C can be realized, and the requirements of the liquid crystal display in most environments can be met.
