PROBLEM TO BE SOLVED: To provide an electroluminescence element which reduces a power consumption, and also to provide an organic electroluminescence device having the same. SOLUTION: An organic EL element 100 includes a hole implantation electrode 2, a hole implantation layer 3, a hole transporting layer 4, an orange light emitting layer 5, a blue light emitting layer 6, an electron transporting layer 7, and an electron implantation electrode 8. A blue color filter layer CFB is arranged under the organic EL element 100. The optical film thickness from the hole implantation electrode 2 to the electron transporting layer 7 is regulated. Thereby, the ratio of the intensity of the second peak of the blue wavelength region to the intensity of the first peak of the short wavelength side is set to 0.73 or less.
