Display substrate, method and device for manufacturing display substrate, and display device

A method for manufacturing a display substrate, comprising:

• shielding a to-be-cut region of a to-be-evaporated substrate with a shielding member;
• and
• evaporating a common layer material onto the to-be-evaporated substrate to form a common layer of the display substrate,
• wherein the display substrate comprises the to-be-cut region and a display region surrounding the to-be-cut region, and the common layer material is deposited onto the display region rather than the to-be-cut region;
• wherein the shielding the to-be-cut region of the to-be-evaporated substrate with the shielding member and evaporating the common layer material onto the to-be-evaporated substrate to form the common layer of the display substrate comprises:
• placing the shielding member into an evaporation chamber after placing the to-be-evaporated substrate into the evaporation chamber, and attaching the shielding member to the to-be-cut region;
• placing a metal mask plate used in the formation of the common layer into the evaporation chamber, and aligning the metal mask plate with the to-be-evaporated substrate;
• and
• evaporating the common layer material onto the to-be-evaporated substrate to form the common layer of the display substrate;
• wherein the shielding member and the metal mask plate are made of different materials;
• and wherein the shielding member and the metal mask plate are placed into the evaporation chamber sequentially.
