Abstract

The invention provides a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a first substrate and a second substrate which are arranged in opposite directions and a liquid crystal layer clamped between the first substrate and the second substrate, a heating electrode is arranged on the side, facing the liquid crystal layer, of the first substrate, that is to say, the heating electrode is arranged in the liquid crystal display panel, heat generated by the heating electrode can directly act on liquid crystal molecules in the liquid crystal layer, and then the purpose that the liquid crystal display panel can be started rapidly in the low temperature environment is achieved; the response speed of the liquid crystal molecules in the liquid crystal layer in the low temperature environment can be increased, the display quality of the liquid crystal display device is guaranteed, and the problem that the response speed of the liquid crystal display device working in the low temperature environment is too slow is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Because it is often required to be in a special working environment, the liquid crystal display device for military or vehicle display is required to be able to adapt to a wide range of ambient temperatures, and sometimes it is even required to work normally within the temperature range of -20°C to 55°C. However, due to the increase of the viscosity coefficient of the liquid crystal material at low temperature, the threshold voltage increases, the response speed becomes slow, and even the phenomenon of liquid crystal crystallization occurs, so that the liquid crystal display device cannot work normally. Take Sharp’s wide-temperature liquid crystal display device as an example. The normal temperature-type device’s low-temperature normal operating point is -5°C, and the wide-temperatu...
