It is an object of the invention to provide a light emitting device in
which burden on a light emitting element having low luminous efficiency
is relieved, and the deterioration of a light emitting element, the
reduction in color reproduction due to the deteriorated light emitting
element, and increase in electric power consumption can be suppressed. A
light emitting device according to the invention has light emitting
elements each of which emits one of colors corresponding to three primary
colors. Further, one feature of the light emitting device according to
the invention has a light emitting element which emits a neutral color.
The light emitting device according to the invention has a structure in
which a plurality of pixels having light emitting elements each of which
emits one of colors corresponding to three primary colors, and a light
emitting element which emits a neutral color as one group, are arranged.
