MANUFACTURING METHOD OF LIQUID CRYSTAL ELEMENT, AND LIQUID CRYSTAL POLYMER FILM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a liquid crystal element wherein alignment treatment of a large surface area is easy, manufacturing time is reduced and mass production is easy, and to provide a liquid crystal polymer film. SOLUTION: A PVCi (polyvinyl cinnamate) substrate 3 having an alignment layer (PVCi film) 2 is manufactured. The film 2 is subjected to rubbing treatment and the easy axis of liquid crystal alignment of the rubbed film 2 is made perpendicular to the rubbing direction. The film 2 is irradiated with non-polarized UV 5 via a photomask 4 for 5 minutes. As a counter substrate 6 such a PI substrate 8 is used, that a easy axis of liquid crystal alignment of a PI film 7 which is formed by applying polyimide(PI) on the counter substrate and heating and rubbing the polyimide is parallel to the rubbing direction. The rubbing directions are combined to be parallel so that the easy axes of the two substrates 3 and 8 are made perpendicular and spacers are dispersed and a liquid crystal is encapsulated between the two substrates 3 and 8 to form a cell. The liquid crystal cell wherein the liquid crystal 9 has about 87°twisted TN alignment 11 in an irradiation part of UV 5 and 0°twisted homogeneous alignment 12 in a non-irradiation part of UV 5 is manufactured.
