To prevent a chromaticity change accompanying with luminosity change in an organic EL element, which is composed by inserting an organic layer containing a luminescence layer between an anode and a negative pole, which counter.
The anode 20, a hole injecting layer 30, a hole transportation layer 40, an hole transporting nature luminescence layer 51, an electron transporting nature luminescence layer 50, the electronic transporting layer 60, an electron injecting layer 70, and the negative pole 80 are formed by laminating one by one on a glass substrate 10. Thickness of a luminescence band width in the electronic transporting nature luminescence layer 50 is set to 30 nm or less by setting the thickness of the electronic transporting nature luminescence layer 50 to 30 nm or less.
