PURPOSE: To provide a liquid crystal cell forming an identification mark different from each other at every cell regardless of performing the exposure processing of respective cell substrate parts of a large-sized substrate by ether one of an en bloc exposure method and a division exposure method.

CONSTITUTION: After at least a transparent electrode and an oriented film are formed on respective cell substrate parts of a pair of large-sized substrate respectively from which plural pieces of cell substrates are extracted, a seal material 26 surrounding a liquid crystal enclosure area and the identification mark 27 consisting of the same material as the seal material and having a pattern different from each other at every cell substrate part 11a are printed on respective cell substrate parts 11a of one side large-sized substarte A simultaneously, and thereafter, a pair of large-sized substrates are joined through the seal material 26, and the large-sized substrate joined body is divided into an individual liquid crystal cell.
