Abstract

A light-emitting substrate includes a base; a first material layer and a second material layer that are disposed on the base, and an etch stop layer between the first material layer and the second material layer. The first material layer is closer to the base than the second material layer. The second material layer includes a plurality of patterns, and each pattern and the first material layer have an overlapping region therebetween. The etch stop layer includes at least portions in respective overlapping regions. A portion of the etch stop layer located in each overlapping region is in contact with the first material layer and the second material layer.
