Abstract:
1. A light-emitting device comprising: a first light-emitting element for emitting a red color comprising a first electrode, a first layer including an organic compound and touching the first electrode, and a second electrode touching the first layer including the organic compound; a second light-emitting element for emitting a green color comprising a third electrode, a second layer including an organic compound and touching the third electrode, and a fourth electrode touching the second layer including the organic compound; a third light-emitting element for emitting a blue color comprising a fifth electrode, a third layer including an organic compound and touching the fifth electrode, and a sixth electrode touching the third layer including the organic compound; and a first transparent substrate and a second transparent substrate which sandwich the first to third light-emitting elements, wherein luminescence passing the first electrode and the first transparent substrate and luminescence passing the second electrode and the second transparent substrate are the same in a color coordinate, wherein luminescence passing the third electrode and the first transparent substrate and luminescence passing the fourth electrode and the second transparent substrate are the same in the color coordinate, and wherein luminescence passing the fifth electrode and the first transparent substrate and luminescence passing the sixth electrode and the second transparent substrate are the same in the color coordinate.
