Patent ID: 7408535

Claim:
A driving circuit for driving an electro-optical panel comprising: a first power line for supplying a first power; a second power line for supplying a second power; a third power line for supplying a third power; a fourth power line for supplying a fourth power; a shift register that generates transfer pulses in synchronization with a clock signal when a transfer-starting pulse is input to the shift register and that outputs an end pulse from a last stage of the shift register, the shift register being connected to the first power line and the second power line; a level shifter that shifts voltage of each of the transfer pulses from a voltage between potentials of the first power and the second power to a voltage between potentials of the third power and the fourth power and that outputs driving signals, the level shifter being connected to the third power line and the fourth power line; a first protective circuit that is provided between the third power line and the fourth power line; a first signal line for supplying the transfer-starting pulse; a second signal line for supplying the end pulse; second protective circuits that are provided between the first signal line and the first power line and between the first signal line and the second power line; and third protective circuits that are provided between the second signal line and the first power line and between the second signal line and the second power line.
