System for manufacturing liquid crystal display device

A system for manufacturing a liquid crystal display device by bonding sheet pieces of optical functional films comprising polarizing films to both surfaces of a rectangular liquid crystal panel, comprising:

• a panel turning mechanism for turning over the liquid crystal panel after one of the sheet pieces of optical functional films is bonded to the liquid crystal panel and before another of the sheet pieces of optical functional films is bonded thereto, wherein
• the panel turning mechanism has:
• a long side-supporting part for supporting the liquid crystal panel by coming into contact with an end face along at least one long side of the liquid crystal panel;
• and a short side-supporting part for supporting the liquid crystal panel by coming into contact with an end face along at least one short side of the liquid crystal panel, and
• the panel turning mechanism turns over the liquid crystal panel about a single axis neither parallel to the long side of the liquid crystal panel nor to the short side of the liquid crystal panel in such a manner that the positional relationship between the long and short sides of the liquid crystal panel is reversed.
