Abstract: A gate voltage generation circuit generates a gate voltage including a first voltage, a second voltage and a third voltage and supplies the gate voltage to a pixel transistor of a display device. The first voltage is a voltage for opening the pixel transistor. The second voltage is lower than the first voltage and is a voltage for closing the pixel transistor. The third voltage is an intermediate voltage between the first voltage and the second voltage. The voltage rises by way of the intermediate voltage at the time of rising from the second voltage to the first voltage.
