METHOD OF MANUFACTURING LIGHT EXTRACTION LAYER FOR LIGHT EMITTING APPARATUS

摘要

A method for forming a light extraction layer for a light emitting apparatus disclosed comprises the steps of: coating a light extraction layer on a substrate of a light emitting apparatus; and etching the light extraction layer to form unevenness on a surface of the light extraction layer. The method can increase light extraction efficiency of the light emitting apparatus with a more simple method by adjusting the surface shape of the light extraction layer using the etching method.
