To provide an electronic device capable of more reliably suppressing a current leak between adjacent elements.SOLUTION: An organic luminescent device 100 includes a plurality of light emitting elements 10 arranged on a substrate 1. Each of the plurality of light emitting elements 10 includes a first insulating layer 3, a lower electrode 2 (first electrode), an organic layer 4 (functional layer), and an upper electrode 5 (second electrode) in mentioned order starting from a side closer to the substrate 1. The organic layer 4 and the upper electrode 5 are continuously arranged to cover two of the lower electrodes 2 independently included in adjacent two of the light emitting elements 10. The first insulating layer 3 has an inclined portion 31 that is inclined relative to the substrate 1. The lower electrode 2 includes a first portion 21 arranged on the inclined portion 31, and a second portion 22 in contact with the organic layer 4, the second portion 22 having a smaller inclined angle relative to the substrate 1 than that of the first portion 21. A thickness of the organic layer 4 arranged on the first portion 21 is smaller than a thickness of the organic layer 4 arranged on the second portion 22.SELECTED DRAWING: Figure 2 【課題】隣り合う素子の間の電流リークをより確実に抑制可能な電子デバイスを提供する。【解決手段】有機発光装置１００は、基板１上に配置された複数の発光素子１０を有する。複数の発光素子１０のそれぞれは、基板１側から、第１絶縁層３と、下部電極２（第１電極）と、有機層４（機能層）と、上部電極５（第２電極）と、をこの順に有し、有機層４および上部電極５は、隣り合う２つの発光素子１０がそれぞれ独立に有する２つの下部電極２を覆うように連続して配置されている。第１絶縁層３は、基板１に対して傾斜した傾斜部３１を有する。下部電極２は、傾斜部３１の上に配置された第１部分２１と、有機層４と接し、基板１に対する傾斜角が第１部分２１よりも小さい第２部分２２と、を有する。第１部分２１の上に配置された有機層４の厚さは、第２部分２２の上に配置された有機層４の厚さよりも小さい。【選択図】図２
