Abstract
A display substrate includes a substrate and a light-emitting device layer which includes a first electrode layer, a light-emitting functional layer, and a second electrode layer that are sequentially stacked in a direction away from the substrate. The first electrode layer includes a reflective layer, an insulating layer, and a transparent conductive layer that are sequentially stacked in the direction away from the substrate. In a red sub-pixel region, a thickness of a first portion of the insulating layer is within a range of about 1000 Å to about 2500 Å. In a green sub-pixel region, a thickness of a second portion of the insulating layer is within a range of about 500 Å to about 2000 Å. In a blue sub-pixel region, a thickness of a third portion of the insulating layer is within a range of about 1500 Å to about 3000 Å.
