Also, a bank defines a formation area of the organic light-emitting layer. Here, the hole-injection layer is a metal oxide layer formed by oxidizing an upper surface portion of the anode composed of the metal layer. Also, a portion of the hole-injection layer that is positioned under the area is depressed so as to form a recess, and upper peripheral edge of the recess is covered with a portion of the bank.
