Abstract: Discussed is a display device including a substrate including a plurality of pixels, a plurality of sub pixels of one of the plurality of pixels including at least one defective sub pixel and a plurality of none-defective sub pixels; a light emitting diode disposed in each of the plurality of sub pixels, a driving transistor having a source electrode connected to a first electrode of the light emitting diode, and a capacitor which includes a plurality of capacitor electrodes connected to a gate electrode and the source electrode of the driving transistor. The plurality of capacitor electrodes is in contact with each other in the at least one defective sub pixel. In the at least one defective sub pixel, the plurality of capacitor electrodes are connected to each other to connect the gate electrode and the source electrode of the driving transistor.
