ELECTROLUMINESCENT DEVICES AND METHODS

摘要

PURPOSE: An electroluminescent device and a manufacturing method thereof are provided to reduce damage to a transferred part of a transfer layer by decreasing an image radioactive level transmitted through an intermediate layer. CONSTITUTION: A cathode(210) is attached to a substrate. A non-patterning emission layer(220) including a first emitter is arranged on the cathode. A patterning emission layer including a second emitter is arranged on the non-patterning emission layer. An additional patterning emission layer(240) is arranged on the non-patterning emission layer. An anode(250) is arranged on the patterning emission layer and the additional patterning emission layer.
