This invention relates to light absorbing inhomogeneous films and their use in luminescent display devices such as cathode ray tubes and electroluminescent panels to achieve high contrast ratio and minimal halation effect, and more particularly to an inhomogeneous film having a composition varying continuously from metal oxide to metal, and the method of making same. The metal is selected from the group consisting of tantalum and vanadium.
