Abstract:
1. An organic light emitting display device comprising: a substrate; a first electrode formed on the substrate and including a first sub-electrode, a second sub-electrode which have different reflectivities with respect to light wavelengths and are mutually stacked; an organic layer formed on the first electrode and including an organic light emitting layer; and a second electrode formed on the organic layer, wherein the organic light emitting layer comprises a stacking of: wherein the first sub-electrode comprises a material of which a reflectivity with respect to a wavelength of the first light is higher than a reflectivity with respect to a wavelength of the second light, and wherein the second sub-electrode comprises a material which has high reflectivity with respect to the wavelength of the second light and low reflectivity with respect to the wavelength of the first light.
