ABSTRACT:
An electro-optical device is disclosed. The electro-optical device comprises pixels arranged in rows and columns. Each pixel comprises at least one complementary TFT (thin film transistor) pair. Each complementary TFT pair consists of an n-channel TFT and a p-channel TFT. The gates of the complementary TFTs of each pixel are all connected to a signal line extending in the Y-direction. The input terminals of the TFTs of each pixel are connected to a pair of signal lines extending in the X-direction. Each pixel has at least one pixel electrode connected to the outputs of the TFTs thereof. In the operation of the electro-optical device, an electric signal is applied to the pair of signal lines extending in the X-direction and an electric signal is applied to the signal line extending in the Y-direction for the duration of the electric signal applied to the pair of signal lines extending in the X-direction.
