Abstract
A display substrate and a preparation method thereof, and a display device are provided. The preparation method includes: forming a display region and a non-display region including an opening region; forming a first barrier wall between the display region and the opening region, in which the first barrier wall surrounds the opening region and includes a first metal layer structure, and a recess is formed on at least one side surface, surrounding the opening region, of the first metal layer structure; and after the first barrier wall is formed, forming a conductive layer pattern in the display region and on the first barrier wall. The forming the conductive layer pattern includes: forming a conductive material layer in the display region and on the first barrier wall, the conductive material layer being disconnected at the first barrier wall; and patterning the conductive material layer to form the conductive layer pattern.
