An object of the present invention is to provide an organic EL display device having high luminance while maintaining an excellent effect of suppressing external light reflection. The organic electroluminescence display device of the present invention includes a polarizer, an optically anisotropic layer, and a light emitting layer in this order, in which the light emitting layer includes at least a plurality of first light emitting layers that emit a first color light, a plurality of second light emitting layers that emit a second color light, and a plurality of third light emitting layers that emit a third color light, on the same plane, and the polarizer has at least two regions selected from the group consisting of a first polarization region in which a transmittance of the first color light emitted from the first light emitting layer is greater than or equal to 60% and an average visible light transmittance is 30% to 55%, a second polarization region in which a transmittance of the second color light emitted from the second light emitting layer is greater than or equal to 60% and an average visible light transmittance is 30% to 55%, and a third polarization region in which a transmittance of the third color light emitted from the third light emitting layer is greater than or equal to 60% and an average visible light transmittance is 30% to 55%.
