Abstract: Disclosed is a display device with high resolution. The display device includes a substrate, a plurality of signal lines on the substrate, multiple buffer layers including at least one organic buffer layer and at least one inorganic buffer layer, and at least one transistor that overlaps one or more of the plurality of signal lines, with the multiple buffer layers interposed therebetween. Accordingly, it may be possible to ensure a sufficient process margin and consequently to realize a high resolution and improve production yield.

Abstract: Disclosed are an organic light emitting display device which may implement high resolution and a method of manufacturing the same. A storage capacitor disposed on a substrate overlaps a plurality of transistors connected to a light emitting element with at least one buffer layer including an organic buffer layer interposed therebetween and, thus, a sufficient process margin may be assured, high resolution may be implemented and yield may be improved.

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.
