发明名称 Active matrix display device and electronic appliance using the same
摘要 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.
