PROBLEM TO BE SOLVED: To provide an organic light emission device that can secure conduction to an upper electrode and is configured so that an architrave area thereof is narrowed.SOLUTION: An organic compound layer 22 coats a lower electrode 21, and an upper electrode 23 coats the organic compound layer 22. A substrate 10 has an electrode pad portion 24 for an upper electrode which is electrically connected to a wire for transmitting power to the upper electrode 23. When the intersection angle between the surface of the substrate 10 and the inclination of the cross-section of the film end 22a of the organic compound layer provided in an area between the lower electrode 21 and the electrode pad portion 24 for the upper electrode is represented by , the following equations (1) and (2) are satisfied. When the intersection angle between the surface of the substrate 10 and the inclination of the cross-section of the film end 22b of the organic compound layer provided in at least a part of the area other than the area between the lower electrode 21 and the electrode pad portion 24 for the upper electrode is represented by , the following equations (3) and (4) are satisfied. (1)tan( )=d/d; (2)tan( )<0.2; (3)tan( )=d/d; (4)tan( )≥0.2. 【課題】上部電極への導通を確保し、かつ額縁領域が狭小化された有機発光装置を提供する。【解決手段】有機化合物層２２が下部電極２１を被覆し、上部電極２３が有機化合物層２２を被覆し、基板１０が、上部電極２３へ送電するための配線と電気接続される上部電極用電極パッド部２４を有し、下部電極２１と上部電極用電極パッド部２４との間の領域に設けられる有機化合物層の膜端２２ａの断面の傾きと基板１０の表面とがなす角度をθ1としたときに、下記式（１）及び（２）が満たされ、下部電極２１と上部電極用電極パッド部２４との間の領域以外の少なくとも一部の領域に設けられる有機化合物層の膜端２２ｂの断面の傾きと基板１０の表面とがなす角度をθ3としたときに、下記式（３）及び（４）が満たされる。（１）ｔａｎ（θ1）＝ｄ1／ｄ2（２）ｔａｎ（θ1）＜０．２（３）ｔａｎ（θ3）＝ｄ3／ｄ4（４）ｔａｎ（θ3）≧０．２【選択図】図１
