Patent ID: 7084848

Claim:
A liquid crystal display device comprising a plurality of scanning lines and plurality of data lines, a scan driver circuit for supplying a scanning signal to said scanning lines, the scan driver circuit comprising polycrystalline silicon, a data driver circuit for supplying digital image data to said data lines, the data driver circuit comprising single crystal silicon, the digital image data having a plurality of binary bits, and a plurality of unit pixels arranged in a matrix configuration, the liquid crystal display device comprising: each of the unit pixels comprising a plurality of subpixels, each of the subpixels comprising a subpixel electrode, a switching element connected to the subpixel electrode, and a voltage controlling capacitor connected to the subpixel electrode; and a plurality of voltage controlling capacitor lines for supplying a compensation voltage signal, each of the voltage controlling capacitor lines being connected to the voltage controlling capacitors in each of the unit pixels; wherein potentials of the subpixel electrodes are for being modulated by varying the potential of such a compensation voltage signal after writing to the subpixels has been completed.
