Drive base plate, light-emitting base plate, and display device

A drive base plate, comprising:

• a substrate;
• and
• a first conductive layer and a first block layer disposed on the substrate, wherein the first conductive layer comprises multiple first conductive portions arranged at intervals, and each of the first conductive portions comprises a first contact pad;
• wherein the first block layer comprises first hollowed-out regions, each of the first hollowed-out regions corresponds to a respective first contact pad, an orthographic projection of the first contact pad on the substrate is within an orthographic projection of the first hollowed-out region on the substrate, and a material of the first block layer comprises an oxidation-resistant material;
• and
• wherein the drive base plate further comprises:
• a second conductive layer located on a side of the first conductive layer facing away from the substrate, the first block layer being located between the first conductive layer and the second conductive layer;
• and
• a first insulation layer located on a side of the first conductive layer facing away from the substrate;
• wherein the first insulation layer comprises:
• a first inorganic layer adjacent to the substrate;
• an organic layer located on a side of the first inorganic layer facing away from the substrate;
• and a second inorganic layer located on a side of the organic layer facing away from the substrate;
• wherein the first block layer is located on a side of the second inorganic layer of the first insulation layer facing away from the substrate, and the second conductive layer is located on a side of the first block layer facing away from the substrate.
