Display device and method for driving same

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 have a function of driving the data lines and a function of measuring a current or a voltage with respect to the pixel circuit;
• and
• a display control circuit configured to output a period specifying signal indicating whether it is in a video signal period or in a non-video signal period and a sampling signal which is in an active level in one line period in the video signal period, wherein
• the scanning line drive circuit includes
• a shift register having a plurality of stages corresponding to the scanning lines,
• a plurality of hold circuits provided corresponding to the scanning lines, each configured to hold a shift register output in accordance with the sampling signal, the shift register output being output from a corresponding stage of the shift register, and
• a scanning signal output circuit provided corresponding to the scanning lines, and configured to output a scanning signal to be applied to a corresponding scanning line, based on at least the period specifying signal, the shift register output, and a hold output which is output from a corresponding hold circuit.
