Patent ID: 8749751

Claim:
A method for producing a plurality of liquid crystal display panels from a panel assembly, the liquid crystal display panels having a panel thickness smaller than that of the panel assembly, the panel assembly being prepared by attaching a first substrate assembly having a plurality of display regions to a second substrate assembly having a plurality of display regions with seals sandwiched between the first and second substrate assemblies so as to surround the opposed display regions of the first and second substrate assemblies, the method comprising: a first thinning step of thinning each of the first substrate assembly and the second substrate assembly by etching the panel assembly; a first scribe-formation step of forming, after the first thinning step, first scribe grooves on an outer surface of the first substrate assembly along regions where the seals are disposed; a second thinning step of further thinning, after the first scribe-formation step, each of the first substrate assembly and the second substrate assembly by etching the panel assembly, and developing the first scribe grooves formed on the outer surface of the first substrate assembly to expose portions of the seals at bottoms of the first scribe grooves; and a second scribe-formation step of forming, after the second thinning step, second scribe grooves on an outer surface of the second substrate assembly along the regions where the seals are disposed.
