PROBLEM TO BE SOLVED: To provide a light emitting device that enables color display with good color balance.SOLUTION: In a light emitting device for color display, a triplet compound is used for a light emitting layer 15 of an EL element emitting red color light, and a singlet compound is used for a light emitting layer 16 of an EL element emitting green color light and a light emitting layer 17 of an EL element emitting blue color light. Thus, operation voltage of the EL element emitting the red color light may be made the same as the EL element emitting the green color light and the EL element emitting blue color light. Accordingly, the color display with good color balance can be achieved. |
