Abstract: A display device includes a substrate, a sub-pixel on the substrate and including an organic light emitting diode, an encapsulation layer on the organic light emitting diode, and a plurality of touch electrodes on the encapsulation layer, the plurality of touch electrodes including an open area. The sub-pixel may include first and second emission areas and a first non-emission area in the open area of the plurality of touch electrodes, the first non-emission area being configured to be in a black state or to have a lower brightness than the first and second emission areas. Each of the first non-emission area and at least one of the first and second emission areas may have a shape of an octagon, a circle, an ellipse, a polygon, a triangle, a square, or a hexagon in a plan view.
