Abstract: A liquid crystal display device includes a liquid crystal display panel including a plurality of pixels, a voltage generator generating a gate on voltage and a gate off voltage, a gate driver generating a gate signal provided to the pixel using the gate on voltage and the gate off voltage, and providing the gate signal to the pixels, a data driver providing a data signal to the pixels, and a timing controller generating control signals that control the gate driver and the data driver. Each of the pixels includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. A voltage level of the gate off voltage provided to the red sub-pixel, a voltage level of the gate off voltage provided to the green sub-pixel, and a voltage level of the gate off voltage provided to the blue sub-pixel are different from one another.
