Abstract

A substrate and an organic electroluminescence device employing the substrate are provided. The substrate has at least one non-continuous photo-resist coating layer formed on at least one surface of a supporting substrate and the non-continuous photo-resist coating has a plurality of continuous portions. The continuous portions may have high surface energy areas and low surface energy areas. A second photo-resist coating layer is used to at least temporarily overlap the continuous portion which corresponds to the high surface energy area in order to form the low surface energy area.
