PURPOSE: A display element drive circuit and a display device are provided to reduce power consumption by restricting a feed-through current in a CMOS output stage of the current drive circuit. CONSTITUTION: A row side scan circuit(10) constructed with a shift register(11) and current drive circuits(12), which operate upon outputs from respective stages of the shift register(11). The shift register(11) is controlled by one-data for vertical scan from a controller. The current drive circuits(12) are provided for row side lines Y1, Y2, . . . , Yi-1 and Yi, respectively, to current-drive the latter lines. Incidentally, only one current drive circuit(12) for the row side line Yi. The current drive circuit(12) receives a discharge pulse signal Pd from a controller(13) and is constructed with a gate circuit(121), which receives an output of the shift register(11), a level shifter(122), which shifts a level of the output "H" or "L" of the gate circuit(121), and an output circuit(123), which receives a "H" or "L" signal from the level shifter(122).
