Abstract
The present application discloses a display substrate. The display substrate includes a base substrate; a plurality of thin film transistors for driving image display on the base substrate; a planarization layer on a side of the plurality of thin film transistors distal to the base substrate; and a pixel definition layer defining a plurality of subpixel regions. The display substrate includes a recess extending into the planarization layer and in an inter-subpixel region of the display substrate. The display substrate further includes a recess fill layer in the recess. The recess fill layer has a light transmittance rate lower than that of the planarization layer.
