摘要： A pixel circuit includes a driver element that is supplied with a potential from a data line. The driver element controls a value of current passing through an electric light emitting element. Upon obtaining a threshold voltage, a conductive member connected to the electric light emitting element is made to be a floating state to cause the driver element to become on-state, variations in the potential of the conductive member caused by charges passing through the driver element to flow into the conductive member are detected by a threshold voltage detector to obtain the threshold voltage of the driver element.
