Patent ID: 7911576

Claim:
A manufacturing method of a liquid crystal display device comprising the steps of: laminating two or more multipiece boards to each other by way of a sealing material; applying surface polishing to at least one of multipiece boards using an etchant; and separating the multipiece boards into respective liquid crystal cells by cutting, wherein the sealing material includes individual sealing materials which are formed for regions of the respective liquid crystal cells, and an outer peripheral sealing material which surrounds the respective individual sealing materials and forms an opening at least in a portion thereof, and the opening formed in the outer peripheral sealing material is sealed by sucking a sealant having viscosity before curing within a range from about 125 to about 840 mPa·s into a gap formed between the multipiece boards, wherein the opening formed in the outer peripheral sealing material is sealed using the sealant remaining after wiping out a surplus amount out of the sealant sucked into the gap formed between the multipiece boards.
