1. A drive circuit comprising:
a setting circuit that includes a first switch configured to connect, to a first voltage line, a video signal line connected to at least one pixel circuit that includes a light emitting element, and is configured to precharge the video signal line to a first voltage supplied from the first voltage line;
an adjustment circuit that includes a current source and a second switch configured to electrically connect the video signal line to the current source during a period according to a video signal, and is configured to adjust a voltage of the video signal line by charging or discharging the video signal line precharged to the first voltage with a current generated by the current source; and
a detection circuit that includes a first terminal connected to a second voltage line and a second terminal connected to the video signal line, and is configured to detect a difference between a second voltage supplied from the second voltage line and a voltage of the video signal line, wherein
the current source is configured to generate the current in accordance with the difference.
