Abstract:
A light emitting device includes a first substrate, a second substrate, a driving circuit, a first electric supply line, and a second electric supply line. In a case where while an image is displayed on the first substrate side, an image is not displayed on the second substrate side, the value of the potential which is supplied to the second electric supply line, to be a value where voltage between both ends of the second light-emitting element falls below the light-emitting threshold voltage. In a case where while an image is not displayed on the first substrate side, an image is displayed on the second substrate side, the value of the potential which is supplied to the first electric supply line, to be a value where voltage between both ends of the first light-emitting element falls below the light-emitting threshold voltage.
