PROBLEM TO BE SOLVED: To provide a drive circuit for a liquid crystal display device which eliminates the arrangement of external capacitors and can drastically reduce the drive current flowing to the drive circuit. SOLUTION: This drive circuit includes plural dynamic controllers. The respective dynamic controllers have operational amplifiers, Schmitt capacitors and plural transistors as switches. The respective dynamic controllers are so constituted as to hold voltage levels so as to be made equal to input voltage levels.
