Abstract: A liquid crystal display device in which an inversion driving scheme is applied to a pixel array which shares data lines. The liquid crystal display device varies driving waveforms of gate signals or data signals according to temperature and may suppress a color deviation of a display panel attributable to inversion of polarities of data signals. A timing controller may be configured to apply control signals to a data drive circuit and a gate drive circuit, the control signals includes a slew rate control pulse that controls the data drive circuit to vary any one of a rising slew rate and a falling slew rate of the data signal corresponding to the main charge interval of each of the gate signals.
