An organic EL cell is formed to satisfy the expression (1): B0B
in which B0 is a normal luminance intensity of luminescence radiated
from a light extraction surface to an observer side, and B is
a luminance intensity of the luminescence at an angle of 50 to 70.
A region for disturbing an angle of reflection/refraction of light is provided
in an optical path in which the luminescence is output from said emitting layer
to the observer side through said transparent electrode. As the region, an anisotropic
scattering resin layer containing a light-transmissive resin, and micro domains
dispersed/distributed in the light-transmissive resin and different in birefringence
characteristic may be formed substantially without interposition of any air layer
in an optical path in which the luminescence is output from the emitting layer
to the observer side through the transparent electrode. At least one kind of luminescent
material is contained in the anisotropic scattering resin layer or between the
anisotropic scattering resin layer and the emitting layer so that the luminescent
material generates fluorescence or phosphorescence when the luminescent material
absorbs the luminescence radiated from the emitting layer as an excitation light source.
