Abstract: The present invention provides a liquid crystal display panel and an alignment method of the liquid crystal display panel. By inputting a voltage equal to a pixel voltage into data black-matrix less (DBS) electrodes at a gray scale 255, rotation of liquid crystals at the DBS electrodes can be consistent with rotation of liquid crystals at the pixel electrodes during an alignment process. Therefore, the present invention improves brightness at the DBS electrodes of the liquid crystal display panel at the gray scale 255, and increases light transmittance of the liquid crystal display panel.

Abstract: A liquid crystal display panel and a display device are provided. A first metal line is disposed on a first substrate of the liquid crystal display panel. An orthographic projection of the first metal line on a pixel electrode covers a first trunk electrode. A voltage difference V1 between the first metal line and a common electrode is small, so that a liquid crystal molecule corresponding to the first metal line does not deflect. In this way, a problem of an insufficient liquid crystal recovery force when the liquid crystal display panel is pressed is resolved, eliminating poor liquid crystal diffusion as a result of pressing and resulting in improving display quality.
