Light emitting element and manufacturing method thereof, and light emitting device using the light emitting element

Abstract

A light-emitting element has a layer including an organic material between a first electrode and a second electrode, and further has a layer including a metal oxide between the second electrode and the layer including the organic material, where these electrodes and layers are laminated so that the second electrode is formed later than the first electrode. The light-emitting element is suppressed damage caused to a layer including an organic material during deposition by sputtering and a phenomenon such as short circuit between electrodes.

What is claimed is: 
     
         1 . A light-emitting element comprising:
 a cathode;   an anode over the cathode;   a first layer comprising an organic material between the anode and the cathode; and   a second layer comprising a metal oxide and a hole-transporting material between the anode and the first layer,   wherein the anode comprises a conductive metal oxide or a metal,   wherein the second layer is in contact with the anode, and   wherein the first layer is in contact with the second layer.
