A lightening apparatus includes light-emitting elements arranged in a matrix. One of the light-emitting elements is located at each intersection between at least two first reference voltage lines and “m” first drive voltage lines. A first reference voltage driver time-divisionally switches the first reference voltage lines. A first drive voltage driver supplies first luminous drive voltages to the first drive voltage lines. One of the light-emitting elements is located at each intersection between at least one second reference voltage line and “m” second drive voltage lines. A second reference voltage driver switches the second reference voltage line. A second drive voltage driver supplies second luminous drive voltages to the second drive voltage lines.
