Patent ID: 7728510

Claim:
An organic light emitting display (OLED) comprising: a substrate; a thin film transistor on a pixel region of the substrate and having a semiconductor layer, a gate electrode, and source and drain electrodes; a first conductive pattern on a metal line region of the substrate at a same layer as the gate electrode; an insulating layer exposing a portion of the first conductive pattern; at least one of a passivation layer or a planarization layer on the thin film transistor, and spaced apart from the metal line region of the substrate; a second conductive pattern in contact with the first conductive pattern; a first electrode electrically connected with the source electrode or the drain electrode; a pixel defining layer on the pixel region excluding the metal line region of the substrate and having an opening which exposes a portion of the first electrode; an organic layer on the exposed portion of the first electrode and comprising at least an organic emission layer; and a second electrode on the organic layer, wherein a portion of the second electrode overlaps with the second conductive pattern and the first conductive pattern.
