Abstract
To provide a structure and a method for driving an active matrix liquid crystal display device having low electric power consumption and high quality image. The active matrix liquid crystal display device of the present invention comprises a plurality of scanning lines and a plurality of signal lines which are disposed in matrix, and a thin film transistor (TFT) and a pixel electrode corresponding to each combination of scanning line and signal line. The scanning line corresponding to each of the pixel electrodes is located on the upper and lower sides of the pixel electrode. The TFT is formed between the scanning line corresponding to the pixel electrode and upper and/or lower portion of the scanning line. An additive capacity is formed between the pixel electrode and a scanning line other than the scanning line corresponding to the pixel electrode. The stored capacity is formed between its corresponding scanning line and one line upper scanning line or between its corresponding scanning line and one line lower scanning line. The stored capacity is located alternately on the neighboring signal lines.
