Light-emitting substrate and method for manufacturing the same, and light-emitting apparatus

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.
