Abstract
Disclosed is an organic light-emitting display device capable of realizing a high resolution. The organic light-emitting display device includes a storage capacitor disposed on a substrate, which overlaps at least one transistor, with at least one buffer layer interposed therebetween, the at least one buffer layer disposed on the storage capacitor, and which includes a lower storage electrode and an upper storage electrode overlapping the lower storage electrode, with a storage buffer layer interposed therebetween, and a light-emitting diode connected to the transistor. One of the lower storage electrode and the upper storage electrode is formed to have the same line width and the same shape as the storage buffer layer, thereby ensuring a sufficient process margin and consequently realizing a high resolution and improving production yield.
