Method Of Fabricating Light Extraction Substrate For OLED

摘要

A method of fabricating a light extraction substrate for an OLE) by which the flatness of the light extraction substrate for an OLED can be increased. Particles of a first metal oxide and a sol of a second metal oxide are inputted and mixed into an organic solvent. A base substrate is coated with a mixture of the first and second metal oxides and the organic solvent. A resultant coating film on the base substrate is heat-treated. The coating film is coated with the second metal oxide to form a metal oxide thin film on the base substrate. In the metal oxide thin film, the particles of the first metal oxide are impregnated in a matrix of the second metal oxide.
