A drive device of a self light emitting display panel which is equipped with a plurality of light emitting elements arranged at intersection positions between a plurality of data lines and plurality of scan lines comprises a first gradation control means ( 21, 24, 25, 26, 30 ) for time-dividing one frame period into N (N is a positive integer) subframe periods to set gradation display by the total of one or plural lighting control periods wherein where a and b are integers which satisfy 0<a<b<N, at an intensity level a, in addition to subframe periods during which lighting is performed at an intensity level a- 1, the first gradation control means allows other one subframe period to be lit, and at an intensity level b, in addition to subframe periods during which lighting is performed at an intensity level b- 1, the first gradation control means allows at least other two or more subframe periods to be lit.
