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.

A light-emitting substrate, comprising:
- a base;
- a first material layer and a second material layer that are disposed on the base, the first material layer being closer to the base than the second material layer, a material of the first material layer including a conductive material or a carrier transport material, the second material layer including a plurality of patterns, and each pattern and the first material layer having an overlapping region therebetween;
- and
- an etch stop layer between the first material layer and the second material layer, the etch stop layer including at least portions in respective overlapping regions, a portion of the etch stop layer located in each overlapping region being in contact with the first material layer and the second material layer, and a material of the etch stop layer including at least one of metal material, metal oxide and metal fluoride.
A light-emitting substrate, comprising:
- a base;
- a first material layer and a second material layer that are disposed on the base, the first material layer being closer to the base than the second material layer, a material of the first material layer including a conductive material or a carrier transport material, the second material layer including a plurality of patterns, and each pattern and the first material layer having an overlapping region therebetween;
- and
- a third material layer between the first material layer and the second material layer, the third material layer including at least portions in respective overlapping regions, a portion of the third material layer located in each overlapping region being in contact with the first material layer and the second material layer, the portion of the third material layer located in each overlapping region having a double-layer structure including a metal layer and a metal oxide layer, a material of the metal layer including metallic aluminum and/or metallic silver, and a material of the metal oxide layer including an oxide of metallic aluminum and/or an oxide of metallic silver.
