The present disclosure provides a display substrate and a method for preparing the same. The display substrate includes a base, and a pixel circuit layer formed on the base, the pixel circuit layer includes a plurality of pixel driving circuits which are arranged in an array along a first direction and a second direction perpendicular to the first direction. The base has recesses, each of which extends in the first direction and has a bottom surface and a side surface, a surface of the base includes the bottom surface and the side surface of each of the recesses, and a top surface between adjacent ones of the recesses, the bottom surface of each of the recesses is substantially parallel to the top surface between adjacent ones of the recesses, the side surface of each of the recesses is at a first angle to the bottom surface of the recess and the top surface between adjacent ones of the recesses, and a portion of each of the pixel driving circuits is formed on the side surface of one of the recesses.
