Abstract
A method for manufacturing a display substrate is provided. The display substrate comprises a first electrode and a second electrode on a base substrate, the display substrate comprises a plurality of sub-pixels, the first electrode comprises a plurality of sub-electrodes corresponding to the plurality of sub-pixels respectively, when a first line extending in a first direction moves in a second direction within an area of each of the sub-electrodes, a distance between two crossing points of the first line and the sub-electrode changes, the first direction being perpendicular to the second direction. The method includes: forming an opaque pixel definition layer on the base substrate on which the plurality of sub-electrodes has been formed, wherein the pixel definition layer comprises light-transmissible openings corresponding to the sub-electrodes respectively, and a location of the pixel definition layer on the display substrate is controlled.
