PROBLEM TO BE SOLVED: To solve the problems of requiring the wiring of a common electrode on the outer side of either end of a column when all one conduction type semiconductor layers for connecting the common electrode are exposed in the same direction and light emission dispersion due to the position deviation of the electrode is easily generated when the one conductivity type semiconductor layers for connecting the common electrode are exposed in the alternating directions in the adjacent island-like semiconductor layer. SOLUTION: In this LED array for which the plurality of island-like semiconductor layers for which the one conductivity type semiconductor layer and an opposite conduction type semiconductor layer are laminated are arranged and provided in a columnar shape on a substrate, the common electrode is connected and provided on the one conductivity type semiconductor layer and an individual electrode is connected and provided on the opposite conductivity type semiconductor layer, the (4N-3)-th (N is a positive integer) and 4N-th one conductivity type semiconductor layers of the plurality of one conduction type semiconductor layers are connected to the same common electrode and the (4N-2)-th and (4N-1)-th one conductivity type semiconductor layers are connected to the other common electrodes. |
