Abstract:
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.
