Abstract
A display apparatus using electroluminescence elements has a substrate, a plurality of anodes arranged generally parallel to each other on a surface of the substrate, and the EL element disposed on the substrate and the anodes. In addition, a material layer is located on the substrate and between the anodes. The material layer may be either a black matrix layer constructed of a light shielding film or a highly reflective multilayer film which suppresses optical crosstalk caused by light scattering originated in the EL element. The material layer covers the anodes such that only a part of each anode corresponding to a display area is exposed. The display apparatus may be used in either a simple matrix display system or an active matrix display system.
