Abstract
An organic light-emitting device (OLED) which exhibits superior light extraction efficiency due to an extraction structure for dipole light generated from an organic light-emitting layer. The OLED includes a first glass substrate, a first electrode disposed on the first glass substrate, an organic light-emitting layer disposed on the first electrode, a second electrode disposed on the organic light-emitting layer, and a second glass substrate disposed on the second electrode. The second electrode has a composite electrode structure including a first transparent electrode layer and a second transparent electrode layer stacked on each other, the refractive index of the second transparent electrode layer being higher than the refractive index of the first transparent electrode layer.
