Abstract

A display substrate and a preparation method thereof, and a display device are provided. The display substrate () includes a display region () and an opening region (), the display region () surrounds the opening region (), a first barrier wall () is between the display region () and the opening region (), and the first barrier wall () surrounds the opening region (); the first barrier wall () includes a first metal layer structure, and at least one side surface, surrounding the opening region (), of the first metal layer structure includes a recess (A/A/A). The display substrate combines the imaging device with the display region of the display substrate and has a better encapsulation effect.
