ABSTRACT:
A liquid crystal display device is provided with a storage capacitor relative to each pixel electrode, and a common electrode is electrically connected to the storage capacitors of adjacent pixel structures between pairs of adjacent scan lines comprising paired odd and even numbered scan lines. With the utilization of this common electrode structure comprising commonly connected capacitor lines, the number of common electrodes necessary for electrically connecting storage capacitors of the pixel structures can be reduced by one-half and the number of the source electrodes connecting portions of the TFTs can be reduced by one-half as compared with the conventional technique utilizing a single storage capacitor per pixel structure. Therefore, a high aperture ratio can be maintained in spite of a decrease in pixel pitch to form a more dense pixel array. The common electrode lines could alternatively be formed between pairs of adjacent signal lines rather than pairs of adjacent scan lines, i.e., the common capacitor connection of the storage capacitors by the common electrodes is primary and the directional orientation of the common electrodes is secondary.
