1. An electronic device comprising elements arranged on a substrate, each of the elements including an insulating layer, a first electrode, a functional layer, and a second electrode in mentioned order starting from a side closer to the substrate, the functional layer and the second electrode being continuously arranged to cover two of the first electrodes independently included in adjacent two of the elements from a position on one of the two first electrodes to a position on the other first electrode,
wherein the insulating layer has an inclined portion that is inclined relative to the substrate,
the first electrode has a first portion positioned on the inclined portion and a second portion in contact with the functional layer, the second portion having a smaller inclination angle relative to the substrate than the first portion, and
a thickness of the functional layer positioned on the first portion in a direction normal to a functional layer surface in contact with the first portion is smaller than a thickness of the functional layer positioned on the second portion in a direction normal to a functional layer surface in contact with the second portion,
the elements include a first element configured to emit first light and a second element configured to emit second light,
each of the first element and the second element further includes, between the second portion and the substrate, a reflecting layer and a portion of the insulating layer in mentioned order starting from the side closer to the substrate,
a thickness of the portion of the insulating layer included in the first element and a thickness of the portion of the insulating layer included in the second element are different from each other,
the insulating layer has a flat portion at a position farther away from the substrate than the second portion,
the reflecting layer is arranged under the second portion and the flat portion,
a thickness of a portion of the reflecting layer in a direction vertical to the substrate, the portion being positioned under the flat portion, is greater than a thickness of a portion of the reflecting layer in the direction vertical to the substrate, the portion being positioned under the second portion, and
the insulating layer is arranged to cover a step formed between the portion of the reflecting layer positioned under the second portion and the portion of the reflecting layer positioned under the flat portion.
