Claim:
1. An organic light emitting diode display, comprising: a substrate; a gate metal layer on the substrate; a gate insulating layer and an etching stop layer on the gate metal layer to expose a portion of the gate metal layer; a first source and drain metal layer on the etching stop layer; a passivation layer on the first source and drain metal layer to expose a predetermined area of the first source and drain metal layer; a second source and drain metal layer on the passivation layer being contacted with the first source and drain metal layer having the exposed predetermined area; an interlayer insulating layer having first and second contact holes through which first and second areas of the second source and drain metal layer are exposed, respectively; and an anode metal layer on the interlayer insulating layer to cover the first contact hole, the anode metal layer being extended to cover the second contact hole.
