Abstract
A manufacture method for a liquid crystal display device and the marks of a substrate thereof is submitted in this present invention. First, a substrate is provided for marked the marks. Then at least one high power light beam is used to focus on and melt the internal part of the substrate for forming the opaque areas. According to the arrangement of the opaque areas, which can be used as the alignment marks or the identification marks. Due to the position of the opaque areas formed by the high power light beam are accurate, the degree of accuracy in the follow-up assembly operation is improved.
