ABSTRACT:
An organic EL device is fabricated by a novel method to reduce the occurrence of poor luminescence in the organic EL device. An anode layer, a hole transporting layer, a luminescent layer, an electron transporting layer, and a cathode layer are laminated in this order on a substrate to form an organic EL device. In the organic EL device, the hole transporting layer is increased in thickness so that foreign particles adhering on the anode layer are substantially covered with the hole transporting layer.
