Abstract: A display device includes a substrate, on which a display area and a non-display area are defined, pixels disposed on the substrate, where the pixels include pixel electrodes disposed in emission areas positioned in the display area, light emitting layers disposed on the pixel electrodes, and a common electrode disposed on the light emitting layers, an insulating layer disposed on the substrate and positioned in a non-emission area between the emission areas of the pixels and the non-display area, and a conductive pattern disposed on the insulating layer to be separated from the pixel electrodes of the pixels, where a first voltage is applied to the conductive pattern. The insulating layer includes a lower insulating layer positioned between the pixel electrodes in the display area, and an upper insulating layer disposed on the lower insulating layer and having a greater area than an upper surface of the lower insulating layer.
