Abstract
A comparator includes: a first amplifying unit that includes a differential pair configured with a pair of transistors which are first and second transistors, and amplifies a difference of signals input to each of the gate electrodes of the first and second transistors, to output; a second amplifying unit that amplifies the signal output from the first amplifying unit; a first condenser that is disposed between a gate electrode of the first transistor and a reference signal supply unit; a second condenser that is disposed between a gate electrode of the second transistor and a pixel signal wiring; a third transistor that connects a connection point of the gate electrode of the first transistor and the first condenser to the pixel signal wiring; and a fourth transistor that connects a connection point of the gate electrode of the second transistor and the second condenser to the pixel signal wiring.
