Abstract: A method for driving a display apparatus uses self luminous elements that allows for favorable display by suppressing a luminance variation accompanying change of a total current amount at a time of on-off drive. In a display apparatus that performs periodic on-off drive, pixels are divided into at least two groups having different light emitting timings with the timing for writing data to the pixels as a reference. Light emission is controlled so that when one group does not emit light, the other group emits light. Alternatively, light emission is controlled so that when one group emits light, the other group does not emit light. In this manner, either the period in which the two groups do not flow current at the same time or the period in which the two groups flow current at the same time hardly exists in one field period.
