To provide a technique advantageous in preventing a reduction in display quality of a light emitting device.SOLUTION: A light emitting device comprises a display area including a plurality of bottom electrodes arranged on a principal surface of a substrate, an organic layer including a light emitting layer arranged to cover the plurality of bottom electrodes, an upper electrode arranged to cover the organic layer, a reflection layer arranged between the principal surface and the plurality of bottom electrodes, and an insulating layer arranged between the reflection layer and the plurality of bottom electrodes. In orthogonal projection with respect to the principal surface, the reflection layer is arranged to overlap the plurality of bottom electrodes. The plurality of bottom electrodes include a first electrode and a second electrode adjacent to each other. An upper electrode contact electrically connecting the reflection layer and the upper electrode is arranged between the first electrode and the second electrode.SELECTED DRAWING: Figure 3 【課題】発光装置の表示品質の低下の抑制に有利な技術を提供する。【解決手段】基板の主面の上に配された複数の下部電極と、前記複数の下部電極を覆うように配された発光層を含む有機層と、前記有機層を覆うように配された上部電極と、前記主面と前記複数の下部電極との間に配された反射層と、前記反射層と前記複数の下部電極との間に配された絶縁層と、を備える表示領域を含む発光装置であって、前記主面に対する正射影において、前記反射層は前記複数の下部電極と重なるように配され、前記複数の下部電極は、互いに隣り合う第１電極と第２電極とを含み、前記第１電極と前記第２電極との間に、前記反射層と前記上部電極とを電気的に接続する上部電極コンタクト部が配される。【選択図】図３
