description	Provided is an output amplifier including a differential unit which sends a current corresponding to a voltage difference between a gradation voltage and an amplified gradation voltage to a first current line; a current mirror unit which sends an amount of current corresponding to the current flowing through the first current line, to a second current line; and an output unit including a first and a second drive line, an output line through which the amplified gradation voltage is output, a first output transistor which sends a current based on a voltage of the first drive line, and a second output transistor which sends a current based on a voltage of the second drive line. The output unit includes a voltage regulation circuit which controls the voltage of the first drive line being higher than the voltage of the second drive line.
