Patent ID: 7402950

Claim:
An active matrix organic light emitting display device, comprising: a substrate; a plurality of data lines formed in one direction and disposed at a given interval on the substrate, a plurality of power supply lines formed in the same direction as the data lines and disposed at a given interval, and a plurality of scan lines disposed at a given interval in a direction perpendicular to the data lines and the power supply lines; at least two thin film transistors and at least one capacitor formed on the substrate, each of the thin film transistors including a semiconductor layer, a gate insulating layer, a gate electrode, and source and drain electrodes connected to semiconductor layer via contact holes, respectively; pixel regions driven by the data lines, the power supply lines, and the scan lines; and each of the pixel regions includes a first electrode electrically connected to at least one of the thin film transistors, an organic layer having at least an organic emission layer, and a second electrode, wherein at least one of the data line and the power supply line is formed to pass over at least one of a source region, a channel region, and a drain region of the semiconductor layer, and wherein the at least one of the data line and the power supply line does not pass over the contact holes.
