Substrate for oled and method of manufacturing the same

摘要

A substrate for an organic light-emitting device (OLED) and a method of manufacturing the same, in which the light extraction efficiency and process efficiency of the OLED can be improved. The substrate (100) for an OLED that includes a base substrate (110), a first metal oxide thin film (120) coating one surface of the base substrate (110), the first metal oxide thin film (120) having a first texture on a surface thereof, a second metal oxide thin film (130) coating the other surface of the base substrate (110), and a third metal oxide thin film (140) coating a surface of the second metal oxide thin film (130).
