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.
