Abstract:
A driver includes a first driving circuit and a second driving circuit. The second driving circuit includes a computation amplifier made up of a transistor with a breakdown voltage lower than a breakdown voltage of a transistor making up the first driving circuit, an output capacitor disposed between an output node of the computation amplifier and a signal supply line, and a first feedback capacitor disposed between an inverting input node of the computation amplifier and the signal supply line. The second driving circuit includes first to m-th voltage outputting capacitors including one end coupled to the inverting input node of the computation amplifier, and first to m-th voltage output circuits configured to output a voltage based on the gradation data to the other end of the first to m-th voltage outputting capacitors.
