Display substrate, display apparatus, and method of fabricating display substrate

A method of fabricating a display substrate, comprising:

• forming an insulating layer on a base substrate;
• and
• subsequent to forming the insulating layer, forming an electrode layer on a side of the insulating layer distal to the base substrate, the electrode layer formed to comprises a plurality of electrode blocks;
• wherein the display substrate is formed to have an electrode block region corresponding to the plurality of electrode blocks, and an inter-electrode block region outside the electrode block region;
• the insulating layer is formed to have a first side distal to the base substrate and a second side opposite to the first side and proximal to the base substrate;
• each of the plurality of electrode blocks is formed to have a third side distal to the base substrate and a fourth side opposite to the third side and proximal to the base substrate;
• and
• the insulating layer and the electrode layer are formed so that the first side of the insulating layer in the inter-electrode block region has a first height relative to a surface of the base substrate greater than a second height of the fourth side of an adjacent electrode of the plurality of electrode blocks relative to the surface of the base substrate.
