Manufacturing Method for Display Substrate, Display Substrate and Display Device

A display substrate, comprising:

• a display area and a bonding area disposed at one side of the display area, wherein the bonding area comprises an isolation area disposed close to the display area and a bonding pad area disposed at one side of the isolation area away from the display area, and the display substrate is manufactured using a manufacturing method, the manufacturing method comprises:
• forming a driving structure layer in the display area of a substrate and forming a bonding structure layer in the bonding area of the substrate, wherein the driving structure layer comprises a pixel driving circuit,
• forming a light emitting structure layer on the driving structure layer in the display area and forming an isolation dam on the bonding structure layer in the isolation area, wherein the light emitting structure layer comprises a light emitting element which is connected with the pixel driving circuit,
• forming an encapsulation structure layer in the display area and forming an inorganic encapsulation layer in the bonding area, wherein the inorganic encapsulation layer envelops the isolation dam, and
• removing the inorganic encapsulation layer in the bonding pad area.
