METHOD FOR MANUFACTURING DISPLAY DEVICE, METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

This method for manufacturing a liquid crystal display device is provided with: a protection film forming step wherein a protection film is formed on a first base material substrate; an element section forming step wherein an element section is formed on the first base material substrate and/or the protection film; a bonding step wherein a bonded substrate is formed by bonding a second base material substrate to the first base material substrate by having the element section therebetween; a first cutting step wherein a first cut is formed at a portion that overlaps the protection film, said portion being on the outer surface of the first base material substrate; an etching step wherein the first cut thus formed is deepened by performing wet etching with respect to the first cut; a second cutting step wherein a second cut is formed at a portion that overlaps the first cut, said portion being on the outer surface of the second base material substrate; and an individually dividing step wherein the bonded substrate is divided along the first cut and the second cut into a plurality of individual bonded substrates.
