Optical device

A method of manufacturing an optical device, comprising,

• a step of forming an organic EL elements on a substrate, the organic EL elements comprising a first electrode, an organic layer, and a second electrode, and one of the first electrode and the second electrode is a first conductive film, and
• a step of forming a second conductive film which is electrically in contact with the first conductive film,
• wherein the first conductive film is formed so as to cover a part of the second conductive film, and
• wherein a plurality of concave portions are provided in a contact surface of the second conductive film which comes into contact with the first conductive film.

• a step of forming a first conductive film which is a first interconnect and is electrically in contact with the first electrode or the second electrode, and
• a step of forming a second conduct film which is a lead-out interconnection and is electrical in contact with the first conductive film and the second conductive film,
• wherein the first conductive film is formed so as to cover a part of the second conductive film, and
• wherein a plurality of concave portions are provided in a contact surface of the second conductive film which comes into contact with the first conductive film.
