Abstract:
An active matrix organic electroluminescent device, comprising:a substrate; a buffer layer on the substrate; a thin film transistor on the buffer layer; a passivation layer on an entire surface of the substrate covering the thin film transistor; a first electrode disposed on the passivation layer to contact the thin film transistor through a contact hole formed in the passivation layer; a first bank layer disposed on the first electrode and on the passivation layer, the first bank layer having a first bank opening exposing a portion of the first 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 electroluminescent layer confined within the first bank opening to electrically contact the first electrode and the first bank layer; and a second electrode formed on the organic electroluminescent layer and on the second bank layer within the first and second bank openings.
