A light emitting device is provided, which uses alternating current drive
as a method of driving the light emitting device, and in which light
emission is always obtained when voltages having different polarities are
alternately applied, and a method of manufacturing the light emitting
device is also provided. A first light emitting element made from an
anode, an organic compound layer, and a cathode, and a second electrode
made from an anode, an organic compound layer, and a cathode are formed.
The light emitting elements are formed sandwiching the same organic
compound layer. The anode of the first light emitting element and the
anode of the second light emitting element, and the cathode of the first
light emitting element and the cathode of the second light emitting
element, are formed on opposite sides of the organic compound layer,
respectively, thus sandwiching the organic compound layer. Note that
voltages having an inverse polarity are applied alternately by the
alternating current drive, and therefore light can always be emitted by
any one of the first light emitting element or the second light emitting
element.
