Abstract: A display device in one example includes a substrate including an active area and a non-active area adjacent to the active area, a plurality of sub pixels disposed in the active area and each including a plurality of transistors, a first passivation layer covering the plurality of transistors, a planarization layer covering the first passivation layer, a second passivation layer covering the planarization layer, an adhesive layer disposed on the second passivation layer, and a plurality of light emitting diodes disposed on the adhesive layer. The first passivation layer and the second passivation contact with each other in the non-active area, so as to seal an end portion of the planarization layer.

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.
