ABSTRACT:
The luminance of different colors of light emitted from EL elements in a pixel portion of a light emitting device is equalized and the luminance of light emitted from the EL elements is raised. The pixel portion of the light emitting device has EL elements whose EL layers contain triplet compounds and EL elements whose EL layers contain singlet compounds in combination. The luminance of light emitted from the plural EL elements is thus equalized. Furthermore, a hole transporting layer has a laminate structure to thereby cause the EL elements to emit light of higher luminance.
