Abstract:
Display unevenness is suppressed. A display device includes pixels (22) arranged in matrix, each including a current-driven type light emitting element (EL) and a drive transistor (Tr3) for supplying a current to the current-driven type light emitting element (EL). The current-driven type light emitting element (EL) is driven by dividing each frame period into a plurality of sub-frame periods for lighting time. The drive transistor is controlled under current write driving using two write currents having a ratio of 1:1/2N and a sum of the two write currents.
