Flat panel display with black matrix and method of fabricating thereof

Abstract

An organic electroluminescent display in which a black matrix with a concentration gradient of a transparent material and a metallic material is formed on the same surface as a pixel electrode. The black matrix and a pixel electrode of the organic electroluminescent display are formed using only one masking operation. The black matrix has a concentration gradient of a continuous gradient structure in which constituents of the transparent material are continuously decreased while constituents of the metallic material are continuously increased as a thickness of the black matrix is increased, a step gradient structure in which the constituents of the transparent material are gradually decreased while the constituents of the metallic material are gradually increased as the thickness of the black matrix is increased, or a multi-gradient structure in which the continuous gradient structure and/or the step gradient structure are repeated.
