Abstract:
A display substrate has a display area and a peripheral area. The display substrate includes a base substrate; a first insulating layer on the base substrate and in at least the peripheral area; a plurality of light emitting elements on the base substrate and in the display area; and an encapsulating layer on a side of the plurality of light emitting elements distal to the base substrate to encapsulate the plurality of light emitting elements. The encapsulating layer includes a first inorganic encapsulating sublayer extending from the display area into the peripheral area. The display substrate has a groove extending into the first insulating layer in the peripheral area, forming a first perimeter substantially surrounding the display area. The first inorganic encapsulating sublayer extends into at least a portion of the groove.
