To provide a technique advantageous for making pixels more minute.SOLUTION: The present invention relates to a light emitting device in which a plurality of pixels are arranged on a main surface of a substrate, each of the pixels including: an organic layer including a light emitting layer; a reflection layer arranged between the main surface and the organic layer; a first insulation layer between the reflection layer and the organic layer; a transmission electrode between the first insulation layer and the organic layer; and a second insulation layer having an opening unit which exposes a part of the transmission electrode and covering the periphery part of the transmission electrode. A trench penetrating the first insulation layer is provided between the periphery part of the transmission electrode and the reflection layer. The transmission electrode is electrically connected to the reflection layer in the trench, and the second insulation layer has a recessed part covering the trench.SELECTED DRAWING: Figure 1 【課題】画素の微細化に有利な技術を提供する。【解決手段】基板の主面に複数の画素が配された発光装置であって、前記複数の画素のそれぞれは、発光層を含む有機層と、前記主面と前記有機層との間に配された反射層と、前記反射層と前記有機層との間に配された第１絶縁層と、前記第１絶縁層と前記有機層との間に配された透過電極と、前記透過電極の一部を露出させる開口部を備えながら前記透過電極の周縁部を覆うように配された第２絶縁層と、を含み、前記透過電極のうち前記周縁部と前記反射層との間に前記第１絶縁層を貫通する溝が設けられ、前記透過電極は、前記溝において前記反射層に電気的に接続され、前記第２絶縁層は、前記溝を覆う部分に凹部を備える。【選択図】図１
