Abstract:
1. A liquid crystal display comprising: a liquid crystal panel having a plurality of pixels respectively arranged in pixel areas; a gate driver that receives a gate-on voltage and a gate-off voltage to sequentially apply the gate-on voltage to the gate lines; a gamma voltage generator that generates a plurality of gamma voltages having voltage levels different from each other; a data driver that generates data voltages based on the plurality of gamma voltages and provides the data voltages to the data lines, respectively; and a gamma voltage compensator that compensates for at least one of the plurality of gamma voltages, which are generated by the gamma voltage generator, by using the gate-off voltage, wherein the gamma voltage compensator comprises at least one capacitor that capacitively couples the gate-off voltage with at least one of the plurality of gamma voltages.
