A display driving device includes a gradation voltage generating section which generates gradation voltage corresponding to display data, a constant current circuit section which supplies a predetermined constant current to a display pixel, a voltage detecting section which detects a voltage of a data line at the time of supplying the constant current as a detected voltage, and a voltage adding section which adds and subtracts the gradation voltage, a reference voltage corresponding to the detected voltage and an intrinsic voltage determined based on a design parameter of a driving transistor provided to the display pixel (driving circuit) so as to generate a pixel data voltage Vpix (=Vref-Vref0+Vdata), and supplies the pixel data voltage as a gradation signal to the data line.
