Abstract
An LCD driving circuit includes a first buffer configured to have a terminal for a first voltage, a terminal for a second voltage and a terminal for an intermediate voltage between the first voltage and the second voltage, and be driven in a range from the first voltage to the intermediate voltage; and a second buffer configured to have a terminal for the first voltage, a terminal for the second voltage and a terminal for the intermediate voltage, and be driven in a range from the intermediate voltage to the second voltage. The terminal for the intermediate voltage of the first buffer and the terminal for the intermediate voltage of the second buffer are connected with each other, and the first voltage is a highest voltage, the second voltage is a lowest voltage, and the intermediate voltage is in a range from the first voltage to the second voltage.
