ABSTRACT:
An electro-optical device and a method of fine gradation display by an electro-optical device are disclosed. In case of driving each picture element of the active matrix type electro-optical device, a visual gradation display can be carried out by using transfer gate complementary field effect transistors, in a structure where one of the input and output terminals thereof is connected with a picture element electrode, by applying a voltage to the other terminal, and by applying a bipolar pulse to a control electrode at a certain timing and cutting the voltage at the same time, and whereby controlling the time for applying voltage to the picture element, while a visual gradation display can also be carried out in a structure where one of the input and output terminals of the device is connected with the picture element, by applying the bipolar pulse to the control electrode at a certain timing and by applying a voltage as a function of time to the other terminal at the same time, and whereby applying the voltage determined thereby to the picture element.
