More Information
Summary:Provided is an organic light emitting diode display device which can improve brightness and color coordinate characteristics in all emission wavelength ranges, and thus can enhance light extraction efficiency and color reproducibility. The organic light emitting diode display device includes a substrate, a first electrode disposed on the substrate, an organic layer disposed on the first electrode and having an emission layer, a second electrode disposed on the organic layer, and first and second refraction layers. A stack of the first and second refraction layers is disposed either between the first electrode and the substrate or on the second electrode. A refractive index of the first refraction layer is smaller than a refractive index of the second refraction layer. A thickness of the first refraction layer is no greater than 100 nm.
