Driver, electro-optical device, and electronic device

摘要

A driver, an electro-optical device, and an electronic device are provided with which a rise in a ground line voltage due to a discharge can be suppressed. The driver includes a voltage generating circuit 100 that generates a first voltage VA1 and a second voltage VA2 for driving a display panel, outputs the first voltage VA1 to a first node NA1, and outputs the second voltage VA2 to a second node NA2, and a discharge circuit 140 that performs a discharge operation if the voltage generating circuit 100 is deactivated. The discharge circuit 140 performs a first discharge operation of discharging the first node NA1, and thereafter performs a second discharge operation of discharging the second node NA2.
