ABSTRACT:
A TFT display device realizing a high degree of fineness by integrally forming a TFT display panel and a drive circuit therefor by using a poly-Si film. The display device comprises TFT transistors of which the gates are connected to the scanning lines and of which the drains are connected to the signal lines that are so formed as to intersect one another substantially at right angles, a TFT display panel having pixel electrodes provided at sources of the TFT transistors, a signal line drive circuit which is formed on the display panel and permits pixel signals that are serially input to be output in parallel, and a scanning line drive circuit which is formed on the display panel and simultaneously selects the two neighboring scanning lines while changing the combination thereof for each of the fields, wherein for the pixels of two rows that are simultaneously selected by the scanning line drive circuit, the signal written into the pixels corresponding to one row has a polarity opposite to that of the signal written into the pixels corresponding to the other row. Therefore, despite the two rows are simultaneously selected, signals of opposite polarities are fed to these rows, whereby flickering decreases and noise transmitted to the signal lines and to a common plate electrode is canceled, making it possible to accomplish stable display operation.
