Abstract

A display device includes: a substrate; a circuit layer disposed on the substrate; a first electrode disposed on the circuit layer; a pixel defining layer disposed on a portion of the circuit layer and the first electrode, wherein an opening is defined in the pixel defining layer; a first light-emitting layer disposed on the first electrode and a portion of the pixel defining layer, wherein at least a portion of the first light-emitting layer overlaps the opening in a plan view; a protective layer disposed on the first light-emitting layer and overlapping the pixel defining layer in the plan view; a capping layer covering a side portion of the first light-emitting layer; and a second electrode disposed on the first light-emitting layer and the capping layer. The protective layer includes a first protective layer disposed on the first light-emitting layer and a second protective layer disposed on the first protective layer and having greater etch resistance than the capping layer.
