Active matrix organic electroluminescent display device and method of fabricating the same

An active matrix organic electroluminescent device, comprising:

• a substrate;
• a buffer layer on the substrate;
• a thin film transistor on the buffer layer;
• a gate line on the buffer layer;
• a first insulating layer on the thin film transistor and the gate line;
• a power line on the first insulating layer over the gate line;
• a second insulating layer on the first insulating layer and the power line;
• a first electrode disposed on the second insulating layer, the first electrode electrically contacts the thin film transistor through a first hole formed in the first and second insulating layers and electrically contacts the power line through a second hole formed in the second insulating layer;
• a passivation layer disposed on an entire surface of the substrate covering the second interlayer insulating layer and the thin film transistor;
• a second electrode disposed on the passivation layer to contact the thin film transistor through a third contact hole formed in the passivation layer;
• a first bank layer disposed on the second electrode and on the passivation layer, the first bank layer having a first bank opening exposing a portion of the second electrode;
• a second bank layer disposed on the first bank layer to have a second bank opening aligned with the first bank opening;
• an organic eleotroluminescent layer confined within the first bank opening to electrically contact the second electrode and the first bank layer;
• and
• a third electrode disposed on the organic electroluminescent layer and on the second bank layer within the first and second bank openings.
