Claim 4:
5. A display device comprising:
a display portion including a plurality of first scanning lines, a plurality of second scanning lines, a plurality of control lines, and a plurality of pixel circuits; and
a driver circuit configured to drive the first scanning lines, the second scanning lines, and the control lines, 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 and 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, and

one of either the first or second compensation transistor is 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 is an N-channel transistor connected to one of the second scanning lines at a control terminal, and
the driver circuit changes a potential of the one of the second scanning lines from high to low level and also changes a potential of the one of the control lines 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.
