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 includes four, subregions, and alignment directions of the upper and lower adjacent subregions as well as the left and right subregions are perpendicular to each other. Alignment directions of any two adjacent subregions respectively located in the upper and lower adjacent subpixels as well as the left and right adjacent subpixels are identical. The alignment directions of any two adjacent subregions respectively located in the vertically adjacent upper alignment region and lower alignment region are identical, so as to reduce dark lines and increase light transmittance.
