This document relates to a liquid crystal display capable of improving picture quality by compensating for difference in charge between liquid crystal cells. The liquid crystal display comprises a liquid crystal display panel; a gate driving circuit; a charge difference compensation circuit configured to generate, in a specific gray level range, analog positive gamma voltages having a first reference level and analog negative gamma voltages having a second reference level in synchronization with a first scan time at which a first gate line is driven, and generate the analog positive gamma voltages having a first compensation level that is lower than the first reference level and the analog negative gamma voltages having a second compensation level that is higher than the second reference level in synchronization with a second scan time at which a second gate line is driven; and a data driving circuit.
