ABSTRACT:
A conductive pattern is formed, by laser scribing, on a soda-lime glass substrate suitable for liquid crystal devices. Besides a first ion blocking film interposed between the glass substrate and the conductive pattern, a second ion blocking film is provided on the structure in order to inhibit sodium ions drift from the substrate during the laser scribing through the pattern formed in the first ion blocking film and the conductive film constituting the pattern.
