Abstract

Abstract PURPOSE:To avert generation of defects in picture element electrodes by providing a metallic layer of an extremely thin film consisting of Ti, Ni, Cr, NiCr, etc., on an SnO2/ITO or ITO layer constituting the picture element electrodes. CONSTITUTION:The metallic layer 30 of the extremely thin film consisting of metal titanium, nichrome, nickel, etc., having an ionization tendency approximate to the ionization tendency of a connecting conductor, for example, Al is formed on the SnO2/ITO or ITO layer constituting the picture element electrodes. Then, the metallic layer 30 forbids the formation of a local battery during patterning even if there is a pinhole in the layer of the connecting conductor, for example, Al. The swelling of the layer consisting of the SnO2/ITO or ITO and the consequent partial stripping are, thereby prevented and the generation of the defects in the picture element electrodes is averted.
