摘要：
A pixel circuit that makes an electro-optical element emit light includes a transistor inserted into a driving current path of the electro-optical element; a current value setting circuit that sets a current value of the driving current path; a level holding unit that stores the level of a supplied image signal; and a comparator circuit that compares the level of the stored image signal with the level of a supplied ramp level signal to control the operation of the transistor on the basis of the comparison result.
