Display device

A display device comprising:

• a substrate including a main display area and a sub-display area surrounded by the main display area and having a plurality of transmission parts;
• a thin film transistor layer including a pixel circuit unit in the main display area on the substrate, a sub-pixel circuit unit not overlapping the transmission parts in the sub-display area on the substrate, and a via layer on the pixel circuit unit and the sub-pixel circuit unit;
• a plurality of main pixel electrodes on the via layer and spaced apart from each other in the main display area;
• a plurality of sub-pixel electrodes and a plurality of dummy pixel electrodes on the via layer and spaced apart from each other in the sub-display area and a plurality of connection electrodes electrically connected to any one of the plurality of dummy pixel electrodes and any one of the plurality of main pixel electrodes, respectively;
• a plurality of light emitting layers on the main pixel electrodes, the sub-pixel electrodes, and the dummy pixel electrodes, respectively;
• and
• a common electrode on the plurality of light emitting layers,
• wherein the main pixel electrodes overlap the pixel circuit unit,
• the sub-pixel electrodes overlap the sub-pixel circuit unit, and
• the dummy pixel electrodes do not overlap the pixel circuit unit and the sub-pixel circuit unit,
• wherein the sub-display area includes a first sub-display area in which the sub-pixel electrodes and the transmission parts are located and a second sub-display area surrounding the first sub-display area and in which the sub-pixel electrodes and the dummy pixel electrodes are located,
