ABSTRACT:
A driving circuit for an electro-optical panel, in which a plurality of pixel portions are provided in an image display region, has a plurality of power supply lines that are respectively supplied with a plurality of power supplies having different potentials from a power supply circuit, a shift register that outputs transfer signals defining timings at which image signals are supplied to the plurality of pixel portions, a level shifter that is connected to at least one power supply line and another power supply line supplied with different potentials among the plurality of power supply lines and that increases the voltage levels of the output transfer signals by using the power supplies having the different potentials supplied through the one power supply line and another power supply line, and an electrostatic protecting circuit having a diode that is provided between the one power supply line and another power supply line and that forms an electrical path to release static electricity applied to one of the one power supply line and another power supply line to the other.
