Abstract:
A dual panel-type organic electroluminescent display device, comprising: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 pattern and is connected to the drain electrode and the second electrode.
