Abstract
A light emitting device includes: a first layer in which a first light emitting element is disposed; a second layer stacked on the first layer and including a second light emitting element that at least partially overlaps the first light emitting element as viewed in a light emitting direction perpendicular to a light emitting surface of the first light emitting element; and a control substrate on which the first layer is stacked and that controls light emission of the first light emitting element and the second light emitting element. The first layer includes a first surface facing the second layer in the light emitting direction, a second surface facing the control substrate in the light emitting direction, and a first opening formed from the first surface to the second surface. The second light emitting element and the control substrate are electrically connected together through the first opening.
