Abstract
A display substrate has a display area and a non-display area. The non-display area includes a dummy pixel area located in a periphery of the display area. The display substrate includes a substrate; a first pixel defining layer disposed on the substrate and located in the display area, the first pixel defining layer having a plurality of first openings; and a second pixel defining layer disposed on the substrate and located in the dummy pixel area, the second pixel defining layer having a plurality of second openings. A capacity of a second opening is greater than a capacity of a first opening, and an open area of a second opening is less than or equal to an open area of a first opening.
