— Of the two types of thermal‐stress processes for glass, i.e. , surface scribing and full body cleavage, the latter is not presently applied in commercial manufacturing due to the technical difficulties, notwithstanding its various advantages. These difficulties, which were pointed out by Kondratenko and were refered to as size effect , consist of a reduced processing speed in a large glass plate and the positional inaccuracy when cleaving close to edges of a glass plate. The result of the investigation aimed to solve these problems, which can pave the way to the commercial application of full body cleavage in the manufacturing of flat‐panel‐display (FPD) devices, is reported.
