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: The present application provides a pixel structure and a display panel. Each of a plurality of sub-pixel units includes a main sub-pixel, at least one secondary sub-pixel, and a thin film transistor electrically connecting the main sub-pixel and the at least one secondary sub-pixel, wherein by controlling a pretilt angle of a first branch electrode of the main sub-pixel to be different from a pretilt angle of a second branch electrode of the secondary sub-pixel, a driving voltage of the main sub-pixel and a driving voltage of the secondary sub-pixel are different, so that color shift can be effectively alleviated and wider viewing angles can be obtained, thus being beneficial to improve an aperture ratio and light transmission of the pixel structure.
