PROBLEM TO BE SOLVED: To provide a driving circuit for liquid crystal display device having a driving buffer which impresses video signal voltage, to which data for screen expression by a large area and high resolution liquid crystal display device is applied, to pixels via a transmission line and the one by improving described technology of Korean patent application number 10-2004-0048446. SOLUTION: The driving circuit for the liquid crystal display device is characterized by including a unit-gain operation amplifier for buffering and carrying a signal voltage on a transmission line, a first switch for switching a connection between a noninverting terminal of the unity-gain operation amplifier and an input line of the signal voltage, a second switch, one end of which is connected to the input line of the signal voltage, a third switch, one end of which is connected to the noninverting terminal of the unity-gain operation amplifier, a first capacitor, one end of which is connected to the other end of the third switch and the other end of which is connected to the other end of the second switch and a second capacitor, one end of which is connected to the other end of the first capacitor and the other end of which is connected to a ground voltage terminal.
