A light-emitting device includes a light-emitting unit, an insulating layer, and a conductive layer to which a predetermined potential is applied. The light-emitting unit includes a first semiconductor layer, a second semiconductor layer having a conductivity type different from a conductivity type of the first semiconductor layer, and a light-emitting layer provided between the first semiconductor layer and the second semiconductor layer. The insulating layer covers the light-emitting unit. The conductive layer is provided in the insulating layer and electrically separated from the light-emitting unit.
