ABSTRACT:
An improved laser patterning method and apparatus is described. A number of parallel grooves can be formed on a glass substrate coated with an ITO film by projecting flat laser pulses while the substrate is continuously sliding. By this process, the process time for producing a substrate for liquid crystal display can be reduced.
