SEMICONDUCTOR DEVICE AND DRIVING METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce power consumption of, and increase the size and definition of a display device by suppressing variation in threshold voltage of a transistor and reducing the number of contact points of a driver IC mounted on a display panel.

SOLUTION: A gate electrode of a transistor which easily deteriorates is connected to a wire to which a high potential is supplied via a first switching transistor and a wire to which a low potential is supplied via a second switching transistor. By inputting a clock signal to the gate electrode of the first switching transistor and an inversion clock signal to the gate electrode of the second switching transistor, the high potential and the low potential are alternately supplied to the gate electrode of the transistor which easily deteriorates.
