Abstract
A liquid crystal display panel and a liquid crystal display device are provided. The liquid crystal display panel includes a first substrate having a plurality of pixel electrodes. Each of the pixel electrodes includes a horizontal trunk electrode and a vertical trunk electrode through which a pixel unit corresponding to the pixel electrode is divided into four light-transmitting areas, and two adjacent light-transmitting areas have different alignment directions. The pixel electrode also includes a plurality of branch electrodes located in the four light-transmitting areas. The branch electrodes are parallel to the horizontal trunk electrode or the vertical trunk electrode.
