Abstract
An object is to provide an active matrix type liquid crystal display apparatus with a substrate for a liquid crystal driving semiconductor device which is free from point defects, rise of production costs, and shortcircuit in a storage capacitance portion. The liquid crystal display apparatus has a substrate for a liquid crystal driving semiconductor device with a display picture element group consisting of driving semiconductor devices 15 and storage capacitances, the display picture element group being disposed on one major surface of a transparent substrate 13, wherein the storage capacitance is formed by disposing an anodic oxide film 18 between a display electrode 16 and a storage capacitance metallic line 1b made of TaN, for example, and disposed on the one major surface of the transparent substrate 13.
