Abstract
The present disclosure provides a display substrate, a method for preparing the same, and a display device including the display substrate. The method includes: forming a conductive layer; forming a first photoresist pattern and a second photoresist pattern on the conductive layer, in which the adhesion between the first photoresist pattern and the conductive layer is less than the adhesion between the second photoresist pattern and the conductive layer; and etching the conductive layer by using the first photoresist pattern and the second photoresist pattern as masks to form a first conductive pattern and a second conductive pattern, respectively, in which a line width difference between the first conductive pattern and the first photoresist pattern is greater than a line width difference between the second conductive pattern and the second photoresist pattern.
