Claim 13:
14. A method for driving a display device having a display portion that includes a plurality of first scanning lines, a plurality of second scanning lines, a plurality of control lines, and a plurality of pixel circuits, wherein
each of the pixel circuits includes a light-emitting element, a drive transistor provided in series with the light-emitting element to control the amount of current flowing through the light-emitting element, a first compensation transistor connected to a control terminal of the drive transistor at a first conductive terminal and an intermediate node at a second conductive terminal, a second compensation transistor connected to the intermediate node at a first conductive terminal, the drive transistor's conductive terminal close to the light-emitting element at a second conductive terminal, and a capacitor connected to the intermediate node at a first electrode and one of the control lines at a second electrode, one of either the first or second compensation transistor being a P-channel transistor connected to one of the first scanning lines at a control terminal, the other of the first or second compensation transistor being an N-channel transistor connected to one of the second scanning lines at a control terminal, and
the method comprises:
driving the first and second scanning lines; and
driving the control lines, wherein,
the one of the second scanning lines has a potential changed from high to low level, and the one of the control lines has a potential changed from a second level to a first level, in an opposite direction to the change in the potential of the one of the second scanning lines, at a time corresponding to the change in the potential of the one of the second scanning lines.
