Abstract: A multi-domain vertical alignment display panel and a pixel structure are provided. The pixel structure includes three subpixels arranged in a row, wherein the three subpixels respectively consist of an upper alignment region and a lower alignment region. The upper alignment region and lower alignment region respectively include four subregions. Alignment directions of the upper and lower adjacent subregions as well as the left and right subregions are perpendicular to each other, and the alignment directions of any two adjacent subregions respectively located in the left and right adjacent subpixels are identical, so as to reduce dark lines between the left and right adjacent subpixels and increase light transmittance.
