Abstract
A display device is constituted by a pair of substrates at least one of which is provided with a display electrode. The display electrode comprises an electroconductive transparent film comprising indium oxide and/or tin oxide and having a surface unevenness of at most 30 Å. The transparent film may preferably be an ITO film containing an amorphous component. The transparent film is effective in improving a surface flatness allowing a good alignment control performance while retaining a good transmittance and a low sheet resistance and is readily etched with weak acid to suppress peeling of an underlying layer thereof and an occurrence of microcracks therein.
