摘要： PROBLEM TO BE SOLVED: To realize a liquid crystal display device formed with a driving circuit of a small size and low breakdown voltage and a display element on the same substrate. SOLUTION: A circuit to drop a pixel potential is formed aside from the driving circuit for supplying a gradation voltage to a pixel. A signal of positive polarity is written to the pixel electrode and the potential of the pixel electrode is dropped by using a capacitor connected to the pixel electrode after the writing. The voltage to be supplied to the pixel electrode is made positive in polarity with respect to the reference potential of a reference electrode and the signal of negative polarity can be created by controlling a pixel potential control signal. If the signal inverted in the polarity by such method is created, the need for supplying the signal of the reverse polarity from the driving circuit is eliminated, and the formation of a peripheral circuit by the elements of the low breakdown voltage is made possible.
