Abstract:
Provided is a thin film transistor (TFT) liquid crystal display device, which is characterized in that an upper substrate is a substrate on which a series of TFT circuits are arranged, and a lower substrate is a thin film transistor TFT substrate. Common electrodes and pixel electrodes of the upper substrate and the lower substrate are alternately configured. The common electrode and pixel electrode of the upper substrate are respectively overlapped with the pixel electrode and common electrode of the lower substrate, so that positions of data lines and scanning lines of the upper substrate and positions of data lines and scanning lines of the lower substrate are overlapped. Thus, in an area corresponding to one scanning line and one data line originally, an original situation that only one pixel may be driven is changed into a situation that the upper and lower substrates both may drive one pixel, so that under the condition that resolutions are the same, the area occupied by the scanning line and the data line is reduced, thereby improving the aperture ratio.
