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.

Abstract: A design for an organic light-emitting display device that increases capacitor capacity and increases aperture ratio by forming an initializing voltage electrode on a different layer than an electrode of the capacitor and forming only one via hole for an entire set of three sub-pixels. One of the source electrodes and the drain electrodes of switching transistors for the three sub-pixels are formed in common, along with the gate electrodes of the switching transistors.

Abstract: A touch screen panel includes first and second sense cells on a same layer and coupling patterns that couple adjacent ones of the first sense cells and adjacent ones of the second sense cells to each other, respectively. The coupling patterns do not cross with each other, thereby improving the ability of the coupling patterns to withstand static electricity. A dummy line formed of a same material as the sense cells may be formed between the first and second sense cells, and the dummy line is electrically coupled to a guard ring located in an area outside of a display area of the touch screen panel, making it possible to overcome the effects of static electricity applied to the front surface of the touch screen panel as well as the side surface thereof.
