ABSTRACT:
A novel structure of an active electro-optic device is disclosed. The device is provided with complementary transistors therein which comprise a p-channel TFT and an n-channel TFT. In case of a liquid crystal electro-optic deivce, the device comprises a pair of substrates, a liquid crystal provided therebetween, picture element electrode islands arranged in matrix form and provided on one of the substrates, complementary transistors provided thereon, and signal lines provided thereon. Gate electrodes of p-channel and n-channel transistors of these complementary transistors are connected to some of the signal lines while source (or drain) electrodes thereof are connected to the electrode islands and drain (or source) electrodes thereof are connected to other signal lines.
