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.
Abstract translation: 本发明的目的是提供一种发光装置，其中减轻了发光效率低的发光元件的负担，并且发光元件的劣化，由于劣化的发光元件引起的色彩再现的减少， 并且可以抑制电力消耗的增加。 根据本发明的发光器件具有发光元件，每个发光元件发射对应于三原色的一种颜色。 此外，根据本发明的发光器件的一个特征是具有发出中性色的发光元件。 根据本发明的发光器件具有这样的结构，其中，具有发光元件的多个像素发出与三原色对应的颜色，并且发射中性色的发光元件作为一组， 。
