Abstract
A pixel circuit includes an OLED that emits light with a luminance corresponding to a current flowing from an anode to a cathode, and a transistor that causes a current corresponding to a voltage between a gate node and a source node. The control circuit supplies a potential to the gate node via a data line in a writing period of a first frame, supplies a potential Vel for setting the transistor to be in an OFF state to the gate node via the data line in a first initialization period, and executes a reset operation in an odd-numbered row and a non-reset operation in an even-numbered row in a second initialization period. The reset operation is an operation of supplying a potential Vorst, and the non-reset operation is an operation of setting the potentials of the data line and anode to a potential between the potential Vel and Vorst.
