摘要： PROBLEM TO BE SOLVED: To provide a manufacturing system and a manufacturing method for a liquid crystal display element capable of reducing the number of processes.SOLUTION: A manufacturing system for a liquid crystal display element comprises a panel reversal mechanism 200 for reversing a liquid crystal panel W to which one sheet piece of an optical functional film has been bonded, before the other sheet piece of an optical functional film is bonded. By the panel reversal mechanism 200, the liquid crystal panel W is reversed around one axis (an axis A1) which is not parallel to either long sides or short sides of the liquid crystal panel W so that positional relation of the long sides and the short sides of the liquid crystal panel W is reversed. Thus, the number of processes can be reduced since the same effect as a case where the liquid crystal panel W is turned upside down and rotated is attained by a single motion.
