PRODUCTION OF LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To smoothly cut a plastic transparent electrode substrate in a good state without producing cracks in a surface hardened layer. SOLUTION: When a plastic mother substrate having a surface hardened layer such as a hard coating layer and an oxygen barrier coating layer is cut into a specified size to obtain a liquid crystal display element in the production process, reinforcing dummy seals 5 are formed on the outside of each corner of a peripheral seal 3. The cutting grooves are formed to pass over the reinforcing dummy seals 5 to cut the plastic substrate.
