To provide an electronic device in which a leak current between a plurality of first electrodes is reduced and a leak current between the first electrode and a second electrode is reduced.SOLUTION: An electronic device according to the present disclosure includes a plurality of first electrodes, a second electrode, a functional layer arranged between the first electrode and the second electrode, and an insulating layer having an inclined portion on the first electrode, wherein the functional layer is continuously arranged so as to cover two adjacent first electrodes from among the plurality of first electrodes and the insulating layer covering each of the two first electrodes, and the layer thickness of the functional layer on the first electrode is smaller than the height from an upper surface of the first electrode to an upper surface of the insulating layer. In the functional layer in the inclined portion of the insulating layer, the layer thickness in a direction perpendicular to an inclined surface of the inclined portion is 20 nm or more.SELECTED DRAWING: Figure 5 【課題】 電子デバイスにおいて、複数の第一電極の間のリーク電流を低減し、かつ第一電極及び第二電極の間のリーク電流を低減した電子デバイスを提供する。【解決手段】 本開示は、複数の第一電極と、第二電極と、前記第一電極と前記第二電極との間に配置された機能層と、前記第一電極の上に傾斜部を有する絶縁層と、を有し、前記機能層が、前記複数の第一電極のうちの隣り合う２つの第一電極と、前記２つの第一電極をそれぞれ覆う前記絶縁層と、を覆うように連続して配され、前記第一電極上の前記機能層の層厚が、前記第一電極の上面から前記絶縁層の上面までの高さよりも小さい電子デバイスであって、前記絶縁層の傾斜部における前記機能層は、前記傾斜部の傾斜面に対して垂直方向の層厚が２０ｎｍ以上であることを特徴とする電子デバイスを提供する。【選択図】 図５
