MANUFACTURING METHOD OF SUBSTRATE FOR OLED

摘要

Disclosed is a manufacturing method of an OLED substrate. A manufacturing method of an OLED substrate, according to an embodiment of the present invention comprises: a first step of forming a plurality of nanostructures separated at fixed intervals to expose part of the surface of the substrate by using a chemical bath deposition (CBD) method on one surface or both surfaces of the substrate; and a second step of etching the exposed part of the substrate and forming an uneven structure on the surface of the substrate.
