PROBLEM TO BE SOLVED: To provide an organic light-emitting device which has a small non-light-emitting region due to short-circuit between electrodes and also has high quality.SOLUTION: There is provided an organic light-emitting device 1 having a plurality of organic light-emitting elements which includes: a lower electrode 21; an upper electrode 23; and an organic compound layer 22 placed between the lower electrode 21 and the upper electrode 23. In the organic light-emitting device 1, a part of an end part of the lower electrode 21 (end part 21b) is covered with an insulation layer 13 which separates the lower electrode 21 and the upper electrode 23, and a portion (end part 21a) not covered with the insulation layer 13 out of the end part of the lower electrode 21 is covered with the organic compound layer 22.SELECTED DRAWING: Figure 1 【課題】電極間の短絡による非発光領域の少ない、高品質な有機発光装置を提供する。【解決手段】下部電極２１と、上部電極２３と、下部電極２１と上部電極２３との間に配置される有機化合物層２２と、を有する有機発光素子を複数有する有機発光装置１であって、下部電極２１の端部の一部（端部２１ｂ）が、下部電極２１と上部電極２３とを離間する絶縁層１３に被覆され、下部電極２１の端部のうち絶縁層１３に被覆されない部分（端部２１ａ）が、有機化合物層２２に被覆されていることを特徴とする、有機発光装置１。【選択図】図１
