Abstract
A display substrate is provided. The display substrate includes an alignment film and a plurality of rows of pixel units arranged in a first direction. Each row of pixel units includes a plurality of pixel units arranged in a second direction. The second direction intersects with the first direction, and the angle between a rubbing direction of the alignment film and the first direction is an acute angle. By setting the angle between the rubbing direction of the alignment film of the display substrate and the first direction to be an acute angle, the contrast of a specific orientation of the display device can be changed.
