A data driving circuit (129) including: a voltage digital-analog converter (230) adapted to generate a first gradation voltage corresponding to external data; a current digital-analog converter (240) adapted to generate a gradation current corresponding to the external data; a voltage control unit (250) adapted to receive a feedback pixel current from a pixel via a data line (D1,...Dj) and to generate a second gradation voltage by increasing or decreasing a level of the first gradation voltage in accordance with the feedback pixel current; a buffer unit (260) adapted to selectively supply the first or second gradation voltage to the data line; and a selection unit (280) adapted to selectively connect the data line (D1,...Dj) to either the buffer unit (260) or the voltage control unit (250). With this configuration, an image is displayed with a desired brightness.
