PURPOSE: A kickback voltage preventing circuit in a liquid crystal display is provided to prevent a kickback voltage owing to a parasitic capacitance by connecting a capacitor to a source electrode of a thin film transistor so as to be supplied with a reverse voltage. CONSTITUTION: A kickback voltage preventing circuit in a liquid crystal display comprises a thin film transistor which has a gate electrode connected to a gate voltage(Vg), a drain electrode connected to a drain voltage(Vd) and a source electrode(S) connected to a liquid crystal. A capacitor(Cgs) is connected to the source electrode(S), and an inverted gate voltage(-Vg) is applied to the capacitor(Cgs).
