A liquid crystal display driving method thereof are provided to prevent open of output terminal by discharging input electric charges increasing a gate voltage of a transistor of an output buffer part. A node controller(110) controls a charging/discharging of a first node(n1) and a second node(n2), and includes a first to a third transistors(T1-T3) controlling the charging/discharging the first node and a fourth to a sixth transistors(T4-T6) controlling the charging/discharging the second node. An output buffer part(120) outputs a common low voltage(VCOML) or a common high voltage(VCOMH) according to the first node and the second node, and includes a seventh transistor(T7), an eighth transistor(T8), a first capacitor(C1), and a second capacitor(C2). A refresh part(130) prevents increase of a gate voltage of the output buffer part, and includes a ninth transistor(T9), a tenth transistor(T10), a plurality of eleventh transistors(T11), a plurality of twelfth transistors(T12), a third capacitor(C3), and a fourth capacitor(C4).
