TOP-EMITTING ELECTROLUMINESCENT DEVICES COMPRISING CATHODE BUS BARS

摘要

A top-emitting display apparatus is provided having a plurality of pixels, said apparatus comprising an anode formed on a substrate (1) , a well-defining layer (2) , the thickness of said well-defining layer being insufficient for it to serve as a spacer for an evaporation mask, an organic electroluminescent layer (8) formed on the anode in each well of the well-defining layer (2) to form said plurality of pixels, a layer of metal (6) formed on the top surface of the well-defining layer (2) , and a transparent cathode layer (9) deposited such that it is formed both on the electroluminescent layer (8) and the layer of metal (6) on the top surface of the well-defining layer (2) . A method for the manufacture of such an apparatus is also provided.
