A liquid crystal display (LCD) device comprises a liquid crystal panel assembly having pixels and thin film transistors, a sensor sensing temperature, a image signal modifying portion receiving image signals and the temperature, calculating a plurality of reference data for modification with respect to the temperature using coefficient of quadratic equation, and generating modified images signals according to the reference data for modification for the image signals for previous and current frame; and a data driving portion converting the modified image signals into data voltages and supplying the data voltages to the liquid crystal panel assembly. According to this configuration, the liquid crystal display device may reduce the size of the memory by calculating modified image signals with respect to the temperature using PQI.
