A liquid crystal display apparatus includes a plurality of sub-pixels configured to be operated by a gate signal transmitted from a gate driver and passing through a gate line and an image signal transmitted from a data driver and passing through a data line, a gamma voltage generator configured to supply gamma reference voltages for expressing gray levels to the data driver, a power supply unit configured to supply a first VDD signal to the gamma voltage generator and a second VDD signal to the data driver and a crosstalk compensation unit positioned between the power supply unit and the gamma voltage generator and configured to filter a ripple of the first VDD signal such that voltage of the first VDD signal is stabilized thereby reducing a level of crosstalk between the sub-pixels adjacent to one another.
