Abstract

An electronic device including 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 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 has a smaller inclination angle relative to the substrate than the first portion. 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.
