Abstract: A display device includes a plurality of pixel electrodes spaced apart from each other, in which each pixel electrode includes a central part and a peripheral part surrounding the central part, a pixel defining layer disposed on the plurality of pixel electrodes and including an overlap part overlapping the peripheral part when viewed in a plan view, and a lateral side to define a pixel opening exposing the central part, in which a portion of the overlap part has an undercut, a light emitting material disposed on the central part exposed through the pixel opening, and a common electrode including a first part disposed on the light emitting material on the central part and a second part disposed on the pixel defining layer, in which the first part is disconnected from the second part along the undercut portion.
