Field sequential liquid crystal display and a driving method thereof

A liquid crystal display device comprising:

• a liquid crystal display panel including a plurality of scan lines for applying scan signals, a plurality of data lines crossing the scan lines, a plurality of pixels formed at areas defined by the scan lines and the data lines and coupled respectively to the scan lines and the data lines, each pixel comprising a switch and a capacitor having one side coupled to the switch and the other side coupled to a common electrode;
• a scan driver for supplying the scan signals to the scan lines;
• a gray scale voltage generator for generating a first gray scale voltage corresponding to first gray scale data for a first pixel among the pixels at a field of a current frame, and for generating a second gray scale voltage corresponding to second gray scale data for the first pixel at the field of a next frame, the second gray scale data having a gray scale level which is different by one level from a gray scale level of the first gray scale data, so as to display a gray scale which has a level that is half-way between the gray scale levels corresponding to the first and second gray scale data;
• a common voltage generator for generating first and second common voltages, and for applying the first common voltage to the common electrode when the first gray scale data is applied, and applying the second common voltage to the common electrode when the second gray scale data is applied;
• a data driver for supplying first and second gray scale waveforms of the first and second gray scale voltages generated by the gray scale voltage generator to corresponding data lines;
• and
• a light source for applying R, G, and B color lights sequentially to the pixels.
