Abstract:
1. An organic light-emitting display panel comprising: a gate line and a data line formed to cross each other on a substrate; an organic light-emitting diode formed in a pixel area defined by the intersection of the gate line and the data line; a power line formed parallel to the data line for supplying an electric current to the organic light-emitting diode; a switching transistor provided at the intersection of the gate line and the data line; a driving transistor connected to the switching transistor and the power line to control the current supplied from the power line; and a storage capacitor composed of a storage electrode overlapping the power line with a first gate-insulating layer disposed therebetween, wherein the storage capacitor includes a groove portion formed on a lateral side of the power line overlapping the storage electrode so that the overlapping area of the power line and the storage electrode is kept constant.
