A display device includes a transistor disposed on a substrate, an organic layer disposed on the transistor and defining grooves, a first pixel electrode disposed on the organic layer, electrically connected to the transistor, and including a pixel metal layer and a pixel protective layer, the pixel protective layer including at least one of an oxide and a halide and surrounding the pixel metal layer, and a dummy electrode disposed on the organic layer, spaced apart from the transistor, and including a dummy metal layer and a dummy protective layer, the dummy protective layer including at least one of an oxide and a halide and surrounding the dummy metal layer.

Display device and method of manufacturing the same

An organic light emitting display device may include a substrate, a first pixel electrode on the substrate, a pixel defining layer on the substrate, the pixel defining layer having an opening exposing a portion of the first pixel electrode, a second pixel electrode on the portion of the first pixel electrode exposed by the opening, a hole injection layer on the second pixel electrode, the hole injection layer including a metal oxide, an organic light emitting layer on the hole injection layer; and a common electrode on the organic light emitting layer.

Organic light emitting display device and method of manufacturing the same

A display apparatus includes: a substrate comprising a main display area, a component area, and a peripheral area; a main pixel electrode at the main display area of the substrate; a main thin-film transistor at the main display area of the substrate and electrically connected to the main pixel electrode; an auxiliary pixel electrode at the component area of the substrate; an auxiliary thin-film transistor at the peripheral area of the substrate; and a connecting wire connected to the auxiliary pixel electrode and including a thin portion having a thickness less than a thickness of the auxiliary pixel electrode, wherein the connecting wire electrically connects the auxiliary thin-film transistor to the auxiliary pixel electrode.
