Claim:
1. An organic light-emitting diode (OLED) display, comprising: a substrate; an active pattern formed over the substrate and including a first region, a second region, a third region, and a fourth region; a gate insulation layer formed over the active pattern and the substrate; a first gate electrode formed over the gate insulation layer and partially overlapping the active pattern, wherein the first gate electrode, the first region and the second region define a first transistor; a second gate electrode formed on the same layer as the first gate electrode, wherein the second gate electrode, the third region and the fourth region define a second transistor, and wherein the second gate electrode, the second region and the fourth region define a third transistor; a first insulating interlayer formed over the first gate electrode, the second gate electrode, and the gate insulation layer; a first conductive pattern formed over the first insulating interlayer and overlapping at least a portion of the third and fourth regions, wherein the first conductive pattern and the overlapping portions of the third and fourth regions define a parasitic capacitor; a first power supply voltage line formed over the first conductive pattern and configured to receive a first power supply voltage; a first light-emitting electrode formed over the first power supply voltage line and electrically connected to the first to third transistors; an organic light-emitting layer formed over the first light-emitting electrode; and a second light-emitting electrode formed over the organic light-emitting layer.
