Method for producing a birefringent film, the birefringent film, an optical compensation layer with the polarizing plate using the same, vertical alignment mode liquid crystal display liquid crystal panel, and a vertical alignment mode liquid crystal display device

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a thin double refraction film, which includes a liquid crystal compound double refraction layer and another double refraction layer, employing a small number of processes.;SOLUTION: In the method, a non-liquid crystal polymer double refraction layer that is orientation processed is used as an orientation layer for the liquid crystal compound. In the method, a process to separately prepare for an orientation layer is eliminated, another orientation layer is not required and the total thickness of the film is made thinner.;COPYRIGHT: (C)2004,JPO&NCIPI
