The optical distance L is given by an optical film thickness nd of an organic material which exists in from the luminescence position to the reflecting face (n is a refractive index and d is a film thickness). When the organic material, which exists from the luminescence position to the reflecting face, consists of a plurality of the layers, the optical distance L is given as the sum of the optical distance (optical film thickness) of each the organic layers.
