This abstract first appeared for US patent application 18554635 titled 'Display Substrate and Display Device

Original Abstract Submitted

A display substrate including a pixel definition layer on a base substrate, the pixel definition layer having a pixel opening, the pixel opening exposing at least a portion of a surface of the first electrode, and at least a portion of the second electrode covering the pixel opening; the pixel definition layer includes a first side surface close to the first electrode, the first side surface includes n stages of first steps sequentially arranged along a light emitting direction of the light emitting functional layer, the first step includes a first step side surface, a slope angle of a first step side surface of a first step of an i-th stage is greater than that of a first step of a j-th stage, and the first step of the i-th stage is located on a side of the first step of the j-th stage close to the base substrate.
