A display device includes a first substrate on which a thin film transistor is disposed, a planarization layer disposed on the first substrate, where the planarization layer includes a plurality of protrusions, a first electrode disposed on the planarization layer, a pixel defining layer disposed on the first electrode, where the pixel defining layer includes a plurality of insulating patterns corresponding to the protrusions, a light emitting layer disposed on the first electrode and the pixel defining layer, and a second electrode disposed on the light emitting layer.

Display device having improved light emission efficiency

An manufacturing method of a display device may include the following steps: forming a transistor on a substrate; forming an insulating layer on the transistor; forming a conductive layer including silver on the insulating layer; forming a photosensitive member on the conductive layer; forming an electrode of a light-emitting element by etching the conductive layer; performing plasma treatment on a structure that comprises the electrode, the plasma treatment using a gas including a halogen; and removing a product that is resulted from the plasma treatment.
