Abstract: A liquid crystal display panel and a liquid crystal display device are disclosed. The liquid crystal display panel has first pixel units and second pixel units, when the liquid crystal display panel displays odd frames, a polarity of each of the first pixel units is changed, and a polarity of each of the second pixel units is maintained.
