A current-control-type light emitting display in which a reverse current
can be supplied to a light emitting element without requiring a negative
power supply and without being passed through a forward drive section. A
first electrode of the light emitting element is connected via a first
switching device to a second power supply line set to 0 V, and is
connected to a drive section via a second switching device. A second
electrode of the light emitting element is connected to a third power
supply line selectively connected to a voltage source from which an
arbitrary positive voltage is supplied or another voltage source from
which 0 V is supplied. A reverse current is supplied to the light
emitting device by setting the potential on the first electrode of the
light emitting element equal to the potential on the second power supply
line and by setting the potential on the second electrode equal to the
potential on the third power supply line from which an arbitrary positive
voltage is supplied.
