Abstract
A dual panel-type organic electroluminescent display device includes a first substrate and a second substrate bonded together to include a plurality of sub-pixel regions, a first electrode on an inner surface of the second substrate, an insulating pattern on the first electrode along a border portion between adjacent sub-pixel regions, a plurality of partition walls on the insulating pattern, a plurality of organic electroluminescent layers, each within one of the sub-pixel regions between adjacent partition walls, a second electrode on the organic electroluminescent layer, a plurality of thin film transistors on an inner surface of the first substrate each within one of the sub-pixel regions, and including a semiconductor layer, a gate electrode, a source electrode, and a drain electrode, a passivation layer covering the thin film transistors and including a contact hole exposing the drain electrode, and a plurality of connection patterns on the passivation layer, each including a first pattern and a second pattern, wherein the first pattern corresponds to the second electrode and has a height larger than a height of the partition walls and the second pattern covers the first patt…
