Abstract
A mask plate is used for manufacturing a pixel definition layer of the display substrate, which includes first transparent patterns and first opaque patterns, and further includes transition structures located between the first transparent patterns and the first opaque patterns. And the transition structures include a plurality of second transparent patterns and second opaque patterns alternately arranged, and a line width of each of the second transparent patterns and each of the second opaque patterns is less than the resolution of an exposure machine by using the mask plate for exposure.
