PROBLEM TO BE SOLVED: To prevent increase in amount of current flowing through ground wiring when the common ground wiring is connected to a plurality of light emitting elements and mutually different power wiring is connected thereto.SOLUTION: Each of first light emitting elements 102 has: a first electrode; a second electrode; and an organic layer. The organic layer has a light emitting layer, which is located between the first electrode and the second electrode. A plurality of power wiring 112 is connected to the first electrode of a mutually different first light emitting element 102, and ground wiring 142 is connected to the second electrode of a plurality of first light emitting elements 102. A control unit 200 is configured to control a current flowing to the plurality of the power wiring 112 to thereby control light emission timing of the plurality of first light emitting elements. Then, the power wiring 112 is configured to repeatedly emit the plurality of first light emitting elements, and shift the light emission timing of the plurality of first light emitting elements 102 during one cycle. |
