Abstract
A light extraction substrate for an organic light-emitting device (OLED) which can improve the brightness of a display or an illumination system to which an OLED is applied by improving light extraction efficiency and a method of manufacturing the same. The light extraction substrate for an OLED includes an oxide or nitride thin film formed on a substrate body. The oxide or nitride thin film includes a base layer formed on the substrate body, a first texture formed on the base layer, the first texture having a plurality of first protrusions which protrude continuously or discontinuously from the base layer, and a second texture having a plurality of second protrusions which protrude continuously or discontinuously from each outer surface of the first protrusions.
