1. A method of manufacturing a display device including light emitting elements that are arranged in a two-dimensional matrix, in which the light emitting elements include a drive circuit and a light emitting portion in which a first electrode, an organic layer having a light emitting layer, and a second electrode are laminated, the method comprising:
providing the drive circuit and a contact portion on the substrate; forming a first insulating layer that covers the drive circuit, the contact portion, and the substrate; forming a first opening, through which a part of the drive circuit is exposed in the bottom, on a portion of the first insulating layer which is located above the drive circuit and forming a third opening, through which the contact portion is exposed in a concave portion and in the bottom, on a portion of the first insulating layer which is located above the contact portion; forming a conductive material layer on the entire surface and patterning the conductive material layer to form the first electrode on the first insulating layer, to form a first electrode extending portion in the first opening, to form an auxiliary electrode layer, which is distant from the first electrode, over a range from an upper area of the first insulating layer to an internal area of the third opening, and to remove the conductive material layer on at least a part of the bottom of the concave portion; removing a portion of the first insulating layer, which is located on an exposed portion in the bottom of the concave portion, to expose the contact portion, forming a second insulating layer on the entire surface, forming a second opening, through which the first electrode is exposed in the bottom, on the second insulating layer, forming a fourth opening, which reaches an exposed portion of the contact portion in the bottom of the concave portion, on the second insulating layer, or forming a second insulating layer on the entire surface, removing a portion of the second insulating layer which is located above the concave portion, removing a portion of the first insulating layer which is located on a portion of the bottom of the concave portion, forming a second opening, through which the first electrode is exposed in the bottom, on the second insulating layer, and forming a fourth opening, which reaches an exposed portion of the contact portion in the bottom of the concave portion, on the second insulating layer and the first insulating layer; forming the organic layer over a range from an exposed portion of the first electrode in the bottom of the second opening to a part of an upper area of the second insulating layer; and forming the second electrode over a range from an upper area of the organic layer to an upper area of the second insulating layer and furthermore to an internal area of the fourth opening.
