LIGHT EMITTING ELEMENT, METHOD FOR MANUFACTURING SAME, AND LIGHT EMITTING DEVICE

摘要

Organic light-emitting elements each have the following structure: a transparent anode, a functional layer including a charge injection layer and an organic light-emitting layer, and a transparent cathode are layered on a substrate in the stated order; a bank defines a formation area of the organic light-emitting layer; the charge injection layer is a metal oxide layer formed by oxidizing an upper surface portion of the anode composed of the metal layer, and a portion of the charge injection layer that is positioned under the area is depressed so as to form a recess; and the upper peripheral edge of the recess is covered with a covering portion of the bank.
