Method of producing laminated type organic electroluminescent element and display apparatus
Abstract:
A method of manufacturing includes providing one of the anode and the cathode, providing a layer of bank portions on the cathode or the anode, the bank portions defining apertures, providing the light emitting units in the apertures, providing the charge-generating portions over the light emitting units, at least one of the charge-generating layers being formed using a depositing device, and providing the other of the anode and the cathode. A display apparatus has a laminated organic electroluminescent element obtained with the manufacturing method. The manufacturing method provides with a high production efficiency an organic EL element having between a cathode and an opposing transparent anode at least one layer of a plurality of light-emitting units partitioned by at least one layer of charge-generating layers.
