Abstract
A display device includes a substrate on which a plurality of sub-pixels including at least one defective sub-pixel are defined; a light emitting element disposed in each of the sub-pixels; a driving transistor disposed in each of the sub-pixels and having a source electrode connected to a cathode of the light emitting element; a capacitor disposed in each of the sub-pixels and connected between a gate electrode and the source electrode of the driving transistor; and a reflector disposed in each of the sub-pixels and electrically connected to the cathode. In the defective sub-pixel, the gate electrode and the source electrode of the driving transistor are electrically connected through the capacitor. Accordingly, according to the present disclosure, the defective sub-pixel can be easily darkened or blackened by performing a welding process on a capacitor including a plurality of electrodes spaced apart from each other in the defective sub-pixel.
