Display substrate, display panel and display apparatus

A display substrate, comprising a base substrate and a plurality of sub pixel units arranged on the base substrate,

• wherein the plurality of sub pixel units is arranged in an array, and the array includes a plurality of rows and a plurality of columns,
• each row and each column of sub pixels includes a first sub pixel and a second sub pixel, a line segment formed by the row of sub pixels has a midpoint in a row direction and a line segment formed by the column of sub pixels has a midpoint in a column direction, the first sub pixel and the second sub pixel are configured for displaying a same color, a distance from the first sub pixel to the midpoint is less than a distance from the second sub pixel to the midpoint, and an aperture area of the first sub pixel is greater than that of the second sub pixel,
• wherein in each row of sub pixels, from a position close to the midpoint in the row direction to a position away from the midpoint in the row direction, and in each column of sub pixels, from a position close to the midpoint in the column direction to a position away from the midpoint in the column direction, the aperture areas of the sub pixels for displaying the same color are reduced in an arithmetic progression mode,
• wherein, the midpoint in the row direction is at an interface between adjacent two of the sub pixels.
