A liquid crystal display is provided, which includes: groups of gate lines transmitting a gate-on voltage; data lines alternately transmitting normal data voltages and an impulsive data voltage; pixels arranged in a matrix and including switching elements that are connected to the gate lines and the data lines and turn on in response to the gate-on voltage to transmit the data voltages; gate driving circuits connected to respective groups of gate lines and sequentially applying the gate-on voltage to the gate lines; a data driver applying the data voltages to the data lines; a duty ratio selector outputting a duty ratio selection signal informing a selected duty ratio; and a signal controller controlling the gate driver and the data driver based on the duty ratio selection signal, wherein the signal controller determines a time for the application of the impulsive data voltage based on the duty ratio selection signal.
