摘要： There is provided an active matrix type semiconductor display device which realizes low power consumption and high reliability. In the active matrix type semiconductor display device of the present invention, a counter electrode is divided into two, different potentials are applied to the two counter electrodes, respectively and inversion driving is carried out each other. Since a potential of an image signal can be made low by doing so, it is possible to lower a voltage necessary for operation of a driver circuit. As a result, it is possible to realize improvement of reliability of an element such as a TFT and reduction of consumed electric power. Moreover, since it is possible to lower a voltage of a timing pulse supplied by the driver circuit, a booster circuit can be omitted, and reduction of an area of the driver circuit can be realized.
