Abstract
Abstract A substrate carrier jig is a jig which supports a substrate of a liquid crystal display element on its surface and carries the substrate with the jig to a process, and a sticky layer whose adhesion for holding the substrate to be stuck to the surface is maintained constantly even after repeated use is provided on a carrier. The substrate composed of a thin sheet glass, plastic, etc. is stuck to the jig, and the substrate with the jig is carried to a process for producing a liquid crystal display element. As a result, it is possible to produce a liquid crystal display element by commonly using a producing line for a conventional liquid crystal display element for glass even if substrate materials such as thin sheet glass, plastic, etc. which independently has no strength and stiffness are used. Furthermore, since the jig can be repeatedly used, cost of producing a liquid crystal display element can be greatly reduced as compared to a disposable jig.
