DISPLAY DEVICE

Abstract:

A display device includes a substrate including a plurality of sub-pixels; a planarization layer disposed on the substrate and including a trench adjacent to the plurality of sub-pixels; a plurality of light emitting elements disposed in the plurality of sub-pixels and sharing an organic layer and a cathode; and an auxiliary electrode disposed in the trench and connected to the cathode. A side surface of the auxiliary electrode has a concave shape. The organic layer has an open portion that is disconnected by the auxiliary electrode. Therefore, it is possible to minimize current leakage through the common layer and prevent an increase in resistance of the cathode by the auxiliary electrode.
