Abstract:
A display device includes a display pixel having: an organic EL element; a capacitor element; a drive transistor having a gate electrode connected to a first electrode of the capacitor element and a source electrode connected to a second electrode of the capacitor element and to an anode electrode of the organic EL element; a first switch element switching a state between a signal line supplying a voltage corresponding to a data signal and the first electrode of the capacitor element, between conducting and non-conducting states; and a resistance unit having a resistance, switching a state between a power line supplying an initialization voltage and the second electrode of the capacitor element between the conducting and non-conducting states, and disposed on a current path from a node that is a connection point of the second electrode and the anode electrode of the organic EL element to the power line.
