A light-emitting device includes a plurality of organic EL elements. Each of the organic EL elements includes a reflection electrode, a hole transport region, an electron-trapping luminescent layer, and a light extraction electrode in this order. The hole transport region has a sheet resistance of 4.0×107 Ω/sq.⋅ or more at a current of 0.1 nA/pixel, and the total thickness of the hole transport region and the electron-trapping luminescent layer is equivalent to an optical path length enabling emission from the electron-trapping luminescent layer to be enhanced.
