There is realized a display device capable of compensating for a deterioration of a circuit element while suppressing an increase of a circuit scale. One horizontal scanning period for a monitor row is composed of: a detection preparation period where preparation for detecting TFT characteristics and OLED characteristics is performed in the monitor row; a TFT characteristic detection period where current measurement for detecting the TFT characteristics is performed; an OLED characteristic detection period where current measurement for detecting the OLED characteristics is performed; and a light emission preparation period where preparation for allowing an organic EL element to emit light is performed in the monitor row. Data lines are used not only as signal lines that transfer a signal for allowing an organic EL element in each pixel circuit to emit light at desired brightness, but also as characteristic detecting signal lines.
