Abstract

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, ···).
