ABSTRACT:
A method for manufacturing edge emission type EL device arrays is disclosed. The method initially involves depositing a first and a second lower electrode layer of different properties. The second lower electrode layer is patterned into a common electrode arrangement conductive to a plurality of edge emission type EL devices. On top of the first and second lower electrode layers, an EL device layer and an upper electrode layer are deposited. The first lower electrode layer is patterned together with the EL device layer and upper electrode layer into a plurality of edge emission type EL devices. The parts ranging from the top edge of the light-emitting edges for the EL devices to the inside of the substrate are etched. This provides a highly smooth light-emitting edge for each EL device.
