A lightening apparatus includes light-emitting elements (P 1,1 , P 1,2, ···) arranged in a matrix. One of the light-emitting elements (P 2,1, P 2,2, ···) is located at each intersection between at least two first reference voltage lines (S2, S5) and "m" first drive voltage lines (Y1, Y2, ···). A first reference voltage driver (3) time-divisionally switches the first reference voltage lines (S2, S5). A first drive voltage driver (6) supplies first luminous drive voltages (B1, B2, ···; E1, E2, ···) to the first drive voltage lines (Y1, Y2, ···). One of the light-emitting elements (P 1,1, P 1,2, ···, P 3,1 ,P 3,2 ,···; P 4,1, P 4,2, ···) is located at each intersection between at least one second reference voltage line (S1, S3; S4) and "m" second drive voltage lines (X1, X2, ···; Z1, Z2, ···). A second reference voltage driver (2, 4) switches the second reference voltage line (S1, S3; S4). A second drive voltage driver (5, 7) supplies second luminous drive voltages (A1, A2, ···, C1, C2, ···; D1, D2, ···) to the second drive voltage lines (X1, X2, ···; Z1, Z2, ···).
