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.
