Light emitting device, light emitting system and method for manufacturing light emitting device

The problem addressed by the present invention is the narrow nature of irradiation areas. This light emitting device is provided with: a light emitting element which comprises a light emitting layer arranged on or above a substrate, and a first element electrode and a second element electrode for applying an electric current or a voltage to the light emitting layer; a first wiring line which is bonded to the first element electrode and electrically connects the first element electrode and a first connection member that is connected to a power supply; and a second wiring line which is bonded to the second element electrode and electrically connects the second element electrode and a second connection member that is connected to the power supply. The light emitting element is a bare chip of an LED element or a bare chip of an organic EL element; and the irradiation angle on the plane intersecting with the substrate is 270° or more.
