Problems solved by technology
However, there are problems in that the cost increases due to the use of expensive equipment, and the overall process becomes complicated due to the manufacture of several optical functional layers by different processes, the processing time increases, and the manufacturing cost is increased
In addition, the light extraction layer formed by photolithography has problems such as weak adhesion to the substrate, and insufficient durability
In addition, because ITO is used as a transparent conductive oxide film layer in the prior art, the manufacturing cost is increased

Abstract
Provided are 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 for an OLED that includes a base substrate, a first metal oxide thin film coating one surface of the base substrate, a second metal oxide thin film coating the other surface of the base substrate, and a third metal oxide thin film coating a surface of the second metal oxide thin film. The first metal oxide thin film has a first texture on a surface thereof.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0067315 filed on Jun. 22, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present application relates to a substrate for an organic light emitting device (OLED) and its manufacturing method, and more particularly, to a substrate for an OLED and its manufacturing method, in which light extraction efficiency and processing efficiency of the OLED can be improved. Background technique [0004] Generally, an organic light emitting device (OLED) includes an anode, a light emitting layer, and a cathode. When a voltage is applied between the anode and the cathode, holes are injected from the anode into the hole injection layer, and then migrate from the hole injection layer to the organic light-emitting layer, and electrons are injected from the cathode into the electron injection l...
