Abstract: PROBLEM TO BE SOLVED: To provide a means to mutually and tightly seal two substrates placed opposite to each other enclosing a fixed amount of a second material (e.g. a liquid crystal) in between without physically or chemically damaging the enclosed material. SOLUTION: The method contains processes for making a liquid crystal material 3 adhere to a central region of a substrate 1, making an epoxy material fillet 4a adhere along and to the periphery of the substrate 1 as a continuous loop so as to surround the liquid crystal material, placing a second glass substrate 2 on the first substrate 1 so as to be continuously brought into contact with the epoxy fillet 4a and subsequently hardening the fillet with curing or cross-linking. Preferably the epoxy fillet is hardened with scanning the epoxy fillet by an infrared or ultraviolet laser converged so as to avoid heating of the liquid crystal material.
