Abstract: In a quartz glass tube body for high-pressure discharge lamp, the devitrification occurs during lighting, a light flux decreases and finally the useful life ends, where the main cause of this devitrification phenomenon is reaction between a sealed substance and the quartz glass tube body. It is one object of the present invention to attain the longer useful life, for example, of a high-pressure discharge lamp by preventing such a phenomenon. According to the present invention, a coating is made up by forming one or more oxynitride layers of an element chosen from among aluminum, tantalum, niobium, vanadium, chromium, titanium, zirconium, hafnium, yttrium, scandium, magnesium, silicon and lanthanum rare earth elements.

Abstract: A liquid crystal display (LCD) panel includes a short-circuit ring formed of aluminum or an aluminum alloy during manufacture. The short-circuit ring is formed along a gate wiring line or a source wiring line. After the panel is inspected for defects, the short-circuit ring is removed. In the LCD manufacturing process, a glass substrate is cut outside the short-circuit ring made of aluminum, and thereafter the short-circuit ring is removed by grinding the short-circuit ring while spraying water having a low resistance on the substrate. The water may include carbon dioxide gas. Low resistance aluminum may be used as the gate wiring line and the short-circuit ring. This aluminum material, which is used as a current supply wiring line, can be subjected to an anodic oxidation process. Thus, it is not necessary to form a film of any metal other than aluminum. This can simplify or reduce the number of fabrication processes.
