Abstract
Provided is a light-emitting device including an organic light-emitting element and a control unit that controls the organic light-emitting element. The organic light-emitting element includes a first electrode, a second electrode, and an organic light-emitting layer which is disposed between the first electrode and the second electrode and in which separation of charges occurs due to incidence of excited light. The control unit changes a potential difference between the first electrode and the second electrode so that recoupling of the charges occurs, in a second period after passage of a delay period from a first period in which the excited light is incident to the organic light-emitting layer.
