ABSTRACT:
A method of cutting a glass substrate to form a plurality of flat panel displays. The method includes forming a scribe line or a line of weakness on a surface of a mother material; treating the mother material with chemical to further weaken the mother material; and cutting the mother material. The scribe line may be formed using a masking technique. The mother material may be treated with chemical by putting the mother material into a chemical solution. Alternatively, the chemical may be sprayed, blown, or exposed to the mother material. The cutting of the mother material may be done by applying mechanical and/or thermal stress along the scribe line.
