Abstract
An organic light-emitting device (OLED) which can improve the light extraction efficiency of the OLED, a method of fabricating the same and an OLED including the same. The light extraction substrate is disposed on one surface of an OLED through which light generated from the OLED is emitted outward, and includes a base substrate and a light extraction layer formed on the base substrate. The light extraction layer has therein a plurality of pores which is formed on the base substrate such that the base substrate forms a bottom surface of the plurality of pores.
