Abstract: Provided is a hybrid light emitting device. The hybrid light emitting device may include the first light emitting part on the substrate, the capping layer, and the second light emitting part. The first light emitting part may emit light having a first wavelength, and the first light emitting part may include a first electrode, an organic emitting layer, and a second electrode sequentially disposed. A second light emitting part may generate light having a second wavelength. A capping layer may be disposed between the organic emitting layer and the second light emitting part. The capping layer may reflect light having the first wavelength and transmit light having the second wavelength.

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.
