PROCESS FOR FORMING AN ORGANIC LIGHT-EMITTING DIODE AND DEVICES MADE BY THE PROCESS

摘要

There is provided a new process for forming a light-emitting diode device having first, second, and third subpixel areas. In the process a hole injection layer is applied over an anode layer. The hole injection material has a conductive polymer and a fluorinated acid polymer. A hole transport layer is applied over the hole injection layer. A first electroluminescent material which is either green or red, is applied to the first subpixel areas. A second electroluminescent material which is either red or green, is applied to the second subpixel areas. A blue electroluminescent material is applied overall, followed by deposition of a cathode. The second electroluminescent material emits a color different from that of the first electroluminescent material.
