To simplify s configuration of a current mode DA converter. A data line driving circuit includes DA converting units U1 to Un. Each DA converting unit U1 to Un a voltage DA converting circuit for generating an analog voltage signal Sv based on image data, a V/I converting circuit for converting the analog voltage signal Sv into an analog current signal Si, and a voltage current selector for selecting one of the analog voltage signal Sv and the analog current signal Si based on a pre-charge control signal CTL. In addition, the analog voltage signal Sv outputted from the voltage current selector serves as a pre-charge voltage, and the analog current signal Si serves as a driving current of an OLED element.
