To provide a light emitting element in which a thyristor is not electrically separated when the thyristor is stacked on top of the light-emitting part.SOLUTION: A light emitting element has a substrate, a light emitting part stacked on the substrate, and a thyristor stacked on the light emitting part and set to emit light or increase the amount of light emitted by the light emitting part when it is turned on, the thyristor having a low resistance layer with resistance that does not electrically separate the thyristor at the position where current from the electrode contacting the thyristor flows.SELECTED DRAWING: Figure 1 【課題】本開示は、発光部の上にサイリスタを積層した場合に、サイリスタを電気的に分離させないことを目的とする。【解決手段】発光素子は、基板と、前記基板上に積層された発光部と、前記発光部上に積層され、オン状態になることで前記発光部を発光、又は、発光量を増加させるように設定するサイリスタであって、前記サイリスタに接する電極からの電流が流れる位置に、前記サイリスタを電気的に分離させない抵抗を有する低抵抗層が設けられた前記サイリスタと、を備える。【選択図】図１
