Abstract

A display base plate includes: a substrate (), a first electrode layer () formed on the substrate (), and a first pixel definition layer () and a second pixel definition layer () formed on the first electrode layer (); the first pixel definition layer () divides the substrate () into a plurality of pixel regions (), each pixel region () includes a plurality of subpixel regions () distributed along a first direction, and two adjacent subpixel regions () are separated by the second pixel definition layer (); in the first direction, surfaces of each pixel region () in contact with the first pixel definition layer () include a plurality of first curved surfaces () and a plurality of second curved surfaces (), and the first curved surfaces () and the second curved surfaces () are protruded away from the pixel region () to which they belong.
