Abstract
An organic electroluminescent display (ELD) device includes a first substrate, a second substrate spaced apart and facing the first substrate, a plurality of switching thin film transistors and a plurality of driving thin film transistors interconnected on the first substrate, each of the switching thin film transistor and the driving thin film transistor having an active layer, a gate electrode, a source electrode, and a drain electrode, the drain electrode of the driving thin film transistor being extended to the pixel region to have an extended portion, a contact electrode contacting the extended portion of the drain electrode of the driving thin film transistor, a first electrode formed on the second substrate, an organic light-emitting layer on the first electrode, and a second electrode on the organic light-emitting layer.
