Display device and drive method therefor

An active-matrix type display device comprising:

• a display unit including a plurality of scanning lines, a plurality of data lines, and a plurality of pixel circuits arranged two-dimensionally;
• a scanning line drive circuit configured to drive the scanning lines;
• a data line drive circuit configured to drive the data lines;
• and
• a measurement circuit including a plurality of measurement units and configured to measure a current or a voltage with respect to the pixel circuit, wherein
• the measurement circuit is configured to perform, at a same timing, a main measurement for measuring the current or the voltage with respect to the pixel circuit with supplying a measurement signal to a part of the measurement units and a dummy measurement for measuring a current or a voltage with supplying a dummy signal to at least a part of remaining measurement units, and perform a calculation on a result of the main measurement and a result of the dummy measurement.
