Abstract:
1. A method of fabricating an organic light emitting display, comprising: preparing a substrate having a display region and a circuit measuring pad region; depositing and patterning a conductive layer on the substrate to form a first conductive layer above the circuit measuring pad region while forming source and drain electrodes above the display region; forming a first insulating layer on the source and drain electrodes and the first conductive layer; simultaneously forming first and second via holes in the first insulating layer, the first via hole exposing the source or drain electrode, the second via hole exposing the first conductive layer; depositing and patterning a conductive layer to form a pixel electrode contacting the source or drain electrode through the first via hole, and a second conductive layer contacting the first conductive layer through the second via hole; and depositing and patterning an insulating layer to form a pixel defining layer which exposes the pixel electrode above the display region and covers the second conductive layer above the circuit measuring pad region.
