Display device and method for manufacturing the same

A method for manufacturing a display device, the method comprising:

• forming a plurality of pixel electrodes spaced apart from each other, wherein each pixel electrode includes a central part and a peripheral part surrounding the central part;
• forming a preliminary-pixel defining layer to cover the plurality of pixel electrodes;
• removing a portion of the preliminary-pixel defining layer to form a pixel defining layer including an overlap part overlapping the peripheral part when viewed in a plan view, and a lateral side defining a pixel opening exposing the central part, wherein a portion of the overlap part has an undercut portion which is recessed from the lateral side;
• forming a light emitting material on the central part exposed through the pixel opening;
• and
• forming 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, wherein the common electrode has a disconnected portion along the undercut portion.
