Patent ID: 7205715

Claim:
A method of fabricating an active matrix organic electroluminescent device, comprising steps of: forming a buffer layer on a substrate; forming a thin film transistor on the buffer layer; forming a passivation layer over the substrate to cover the thin film transistor; forming a first electrode on the passivation layer to electrically contact the thin film transistor through a contact hole formed in the passivation layer; forming a first bank layer on the first electrode and on the passivation layer; forming a second bank layer on the first bank layer; forming a bank opening through the first and second bank layers to expose a portion of the first electrode; forming an organic electroluminescent layer within the bank opening to contact the first electrode and the first bank layer; and forming a second electrode on the organic electroluminescent layer and on the second bank layer, wherein the bank opening is spaced apart from the thin film transistor, sidewalls of the first and second bank layers defining the bank opening are coplanar, and both the first and second bank layers include an organic material.
