Abstract:
An electro-luminescence device has an anode and a cathode, between which a hole transporting layer, an emitting layer and a hole insulating layer are provided. The emitting layer is made of a material including a light emitting material of polymer doped with two light emitting materials of molecule. A method of making the electro-luminescence applies the wet process to make the hole insulating layer and the emitting layer to simplify the steps and to control the factors of fabrication.
