To provide an organic device with a reduced leakage current between pixels.SOLUTION: There is provided an organic device including a first element and a second element disposed adjacent to the first element. The first and second elements include a first electrode, a second electrode, an organic layer disposed between the first and second electrodes, and an insulation layer covering the first electrode. The insulation layer has an eaves shape including a protruding portion protruding from the insulation layer of the first element toward the second element. The organic layer includes a charge transport layer and a functional layer. The following factors satisfy a specific relationship: t representing a total film thickness of the organic layer in the eaves shape, t' representing a film thickness of the charge transport layer in the eaves shape, x1 representing a protruding amount of the eaves shape, x2 representing a distance between the eaves shapes of the first and second elements, and y representing a distance from a lower surface of the first electrode to the protruding portion of the eaves shape.SELECTED DRAWING: Figure 1 【課題】画素間リークを低減した有機デバイスを提供する。【解決手段】第１の素子とその隣に配される第２の素子を含む有機デバイスであって、第１及び第２の素子は、第１の電極と、第２の電極と、第１の電極と第２の電極との間に配置されている有機層と、第１の電極を覆う絶縁層と、を有し、絶縁層は、第１の素子の絶縁層から第２の素子に突き出された突き出し部を有する庇形状を有し、有機層が電荷輸送層と機能層とを有し、庇形状において有機層の合計膜厚をｔ、庇形状において電荷輸送層の膜厚をｔ'、庇形状の突き出し量をｘ１、第１の素子の庇形状と、第２の素子の庇形状との間の距離をｘ２、第１の電極の下面から庇形状の突き出し部までの距離をｙとするとき、それらの因子が特定の関係を満たす有機デバイス。【選択図】図１
