Abstract: A liquid crystal display device includes a liquid crystal panel which includes gate lines, data lines crossing the gate lines, and pixels connected to the gate lines and the data lines; a timing controller for receiving a control signal and image data and for generating a gate control signal and a data control signal; a gate driver for generating a gate signal based on the gate control signal and outputting the gate signal to the gate lines; and a data driver for performing data conversion on the image data based on the data control signal and outputting a conversion result to the data lines, wherein the timing controller analyzes the image data frame by frame data and applies two or more inversion driving techniques to frame data.
