Abstract: A display substrate and a display device including the display substrate are disclosed. In one aspect, the display substrate includes a plurality of pixels formed in a substantially circular pixel area and a driving circuit formed in a peripheral area surrounding the pixel area and configured to drive the pixels. A boundary is formed between the pixel area and the peripheral area, and the boundary is substantially concentric with respect to an arc defining the substantially circular pixel area. The driving circuit comprises a conductive pattern having a first side which extends in a peripheral direction crossing the boundary.
