Abstract:
An image display device includes: an organic EL element, a first electrostatic capacitor, a driving transistor having a gate connected to a first electrode of the first electrostatic capacitor and a source connected to an anode of the organic EL element, a second electrostatic capacitor having an electrode connected to a second electrode of the first electrostatic capacitor, a negative power source line which determines the potential of a cathode of the organic EL element, and a scanning line driving circuit which controls a first switching transistor, a second switching transistor, and a third switching transistor. In a non-light-emitting period, the scanning line driving circuit sets, during a period from a start of a reset period to an end of the non-light-emitting period, a fixed voltage corresponding to the potential of the negative power source line to the source electrode of the driving transistor.
