<p>PROBLEM TO BE SOLVED: To provide a light emitting diode to which a plurality of light emitting cells are electrically connected on a substrate.SOLUTION: A light emitting element 300 includes: a substrate; a plurality of light emitting cells 100 and 200; and at least four electrodes formed on the substrate. A plurality of light emitting cells constitutes a first light emitting cell block and a second light emitting cell block. A first electrode 310 in four electrodes is connected to among an anode of a first light emitting cell in the second light emitting cell block, a cathode of a fourth light emitting cell, and an AC power supply. A second electrode 320 is connected to among the anode of a second light emitting cell in the second light emitting cell block, the cathode of a third light emitting cell, and the AC power supply. A third electrode 330 is connected to among the cathode of first light emitting cell, the cathode of second light emitting cell, and an external circuit connected to one end of the anode side in the first light emitting cell block. A fourth electrode 340 is connected to the anode in first light emitting cell block.</p> |
