A light emitting device includes a pixel defining layer including a plurality of pixel defining layer elements, on a substrate; a first electrode in a space defined by the substrate and the pixel defining layer; a light emitting layer in a space defined by the first electrode and the pixel defining layer; and a second electrode on the light emitting layer and the pixel defining layer. The second electrode includes a plurality of layers, and an insulating layer between the plurality of layers, overlapping the light emitting layer, and exposing a layer among the plurality of layers in an area corresponding to the pixel defining layer.
