In a setup period, switches are in an ON state, and in a drive period, a switch is in an ON state. A voltage comparison unit compares the voltage Vin in the setup period and a voltage Vout in a drive period to output a comparison result voltage. A push-pull output unit includes a TFT for charge and a TFT for discharge. A drive control unit controls the TFTs to be in an OFF state in the setup period, and in the drive period, selectively controls the TFTs to be in an ON state in accordance with the comparison result voltage. If Vout<Vin, the comparison result voltage rises, the TFT becomes in an ON state, a voltage at a node falls, the TFT becomes in the ON state, and the voltage Vout rises. Thus, there is a provided a small-sized capacitive load drive circuit with low power consumption and robust against process variation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive load drive circuit and display device including the same","description":"A buffer circuit drives a capacitive load based on a voltage Vin.
