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.

Mask plate, display substrate and manufacturing method thereof, and display device

The present disclosure relates to a display substrate and a display device thereof. The display substrate comprises: a substrate; a first wiring extending in a first direction on the substrate; a first dielectric layer on the substrate and the first wiring; a second wiring extending in the first direction on the first dielectric layer, wherein an orthographic projection of the second wiring on the substrate at least partially overlaps with an orthographic projection of the first wiring on the substrate; a conformal dielectric layer on the first dielectric layer and the second wiring; a third wiring and a fourth wiring disposed at spacings in the first direction on the conformal dielectric layer, wherein orthographic projections of the third wiring and the fourth wiring on the substrate at least partially overlap with the orthographic projections of the first wiring and the second wiring on the substrate.
