Abstract

When a clock signal pulse number and a compensation-target-line address indicating a compensation-target row match, the following control is carried out with a time point being a starting point of a current measurement period, the time point being one horizontal scanning period after a time point of the match. At a current measurement period starting point and ending point, only the potential of the one of the clock signals applied to a unit circuit corresponding to the compensation-target row is changed. Throughout the current measurement period, the clock operation of the clock signals is stopped. A monitor enable signal, that is applied to a control terminal of an output control transistor for controlling active signal output to a monitor control line, is only set to a high level during the current measurement period.
