Abstract
A mother glass board used to fabricate multiple liquid crystal display panels includes a substrate on which the liquid crystal panel portions are formed. An orientation film is formed on the liquid crystal panel portions. A pattern of metallic film is formed on the substrate outside that portion of the substrate on which the liquid crystal panel portions are located. The patterns include an alignment mark and an identifier mark used in the liquid crystal panel production process. An enclosure surrounding the liquid crystal panel portions is formed on the substrate between the pattern and the liquid crystal panel portions. The enclosure prevents stripes from being formed on the orientation film during a rubbing step in the production process in which the liquid crystal panel portions are rubbed with a cloth.
