The display device may further include a third capacitor electrode overlapping the first capacitor electrode and the second capacitor electrode, in which the first capacitor electrode and the second capacitor electrode may overlap each other with the first insulating layer therebetween, so as to form a first storage capacitor, and the second capacitor electrode and the third capacitor electrode may overlap each other with the second insulating layer therebetween, so as to form a second storage capacitor.

Another exemplary embodiment of the present invention provides a method of manufacturing a display device, including: forming signal lines on a substrate, the signal lines including a gate line, a data line, and a driving voltage line collectively defining an outer boundary of a pixel area; forming a transistor on the substrate, the transistor being connected to the signal line; forming a first electrode extending across the pixel area, the first electrode being connected to the transistor, and disposed on the signal line and the transistor, the first electrode further having a first portion and a second portion, the first portion overlying only the signal line and the transistor, and the second portion including all of the first electrode not included in the first portion; forming a pixel defining layer on only the first portion of the first electrode; forming an organic emission layer disposed on substantially the entire second portion but not on the first portion; and forming a second electrode on the pixel defining layer and the organic emission layer.

The organic emission layer may not be formed on the pixel defining layer.
