Patent ID: 8022898

Claim:
A flat display device having a display region including at least two thin film transistors and a pixel, comprising: a scan line electrically connected with a gate electrode of a first thin film transistor; a data line electrically connected with either a source electrode or a drain electrode of the first thin film transistor; a first electrode electrically connected with either a source electrode or a drain electrode of a second thin film transistor; a driving line that supplies uniform power to the display region; an auxiliary driving line electrically connected with the driving line; an intermediate layer comprising at least an emission layer; and a second electrode, wherein the auxiliary driving line and the driving line are in a different layer from each other, the auxiliary driving line being formed directly on the same layer as the first electrode, the driving line being formed directly on the same layer as the source electrode and the drain electrode, wherein each end of the driving line is coupled to a driving power supply line, wherein the intermediate layer is disposed between the first electrode and the second electrode, wherein a light emitting unit comprises the first electrode, the intermediate layer, and the second electrode, and the first electrode is either an anode or a cathode of the light emitting unit, and wherein the driving line is electrically connected with the first electrode to supply uniform power to the light emitting unit.
