Abstract: A liquid crystal display device includes: a liquid crystal display panel including a red pixel, a green pixel, and a blue pixel connected to one data line; a data driver applying a data voltages; a data analyzing unit analyzing the data voltages; and a data modulation unit inverting a polarity of the data voltages. A first, second and third data voltage are applied to one of the red pixel, the green pixel, and the blue pixel, and when a difference between the first data voltage and a gamma reference voltage is less than a difference between each of the second and third data voltages and the gamma reference voltage, and a difference between the first data voltage and each of the second and third data voltages is a predetermined value or more, the data modulation unit inverts a polarity of the first data voltage.
