ABSTRACT:
A substrate for forming a liquid crystal display panel has panel forming areas 14 defined on a glass base plate 12. Patterns (such as wiring TAB areas 22) are defined on the glass base plate 12 within the panel forming areas. The panel forming areas and the patterns within the panel forming areas are defined in position and orientation with respect to a scribing line that passes through the center of the glass base plate such that when the glass base plate is divided along the scribing line, two base plates are formed that are identical to each other after one is rotated by 180 degrees. The resulting halves of the original base plate thus do not include the wasted area that conventionally needs to be cut off when the panel forming areas and patterns are not formed with such position and image symmetry. A large margin is also assured, which facilitates cutting and improves the production yield. It also allows the image area portion of the panel forming areas to be enlarged.
