Abstract
A buffer circuit driving method for driving a buffer circuit including: an output terminal; a first transistor connected to a signal source of a clock signal that is of at least a first voltage or a second voltage lower than the first voltage, for supplying the first voltage to the output terminal; and a second transistor connected to a voltage source that supplies a third voltage lower than the first voltage, for supplying the third voltage to the output terminal, includes: causing the first transistor to switch to a conducting state in a period where the clock signal is of the first voltage; and causing the first transistor and the second transistor to switch to the conducting state in a period where the clock signal is of the second voltage, following the period where the clock signal is of the first voltage.
