ABSTRACT:
It is an object of the present invention to provide an active matrix display device in which reliability of transistors in a pixel can be improved by reducing a voltage applied to the transistors. The active matrix display device includes a capacitor of a pixel provided for each pixel, storage capacitors provided for each pixel, a transistor in a first group, a transistor in a second group, and a data line. When the transistor in the first group is off and the transistor in the second group is on, the storage capacitors which store charge in accordance with a potential difference of a potential of the data line and a reference potential are connected in series and a voltage obtained by raising the potential difference is applied to the capacitor of the pixel and therefore, the voltage applied to the transistors can be reduced.
