Abstract: Disclosed are organic light emitting devices and methods of fabricating the same. The organic light emitting device may include light scattering parts having irregular island-shapes irregularly arranged. The organic light emitting device may further include a planarization layer, a first electrode, an organic light emitting layer, a second electrode, and an encapsulation layer. The light scattering parts may be formed using an organic solution having a low refractive index to improve light extraction efficiency of the organic light emitting device. Additionally, the light scattering parts of the irregular island-shapes may improve the light extraction efficiency of lights of all wavelengths, so as to be applied to an organic white light emitting device. The light scattering parts of the irregular island-shapes may be formed using the organic solution by a dewetting phenomenon. The light scattering parts may be formed at a temperature of about 250 degrees Celsius or less.
