Title:
LIQUID CRYSTAL MEMBER AND MILLIMETER WAVE MODULATION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/091733
Kind Code:
A1
Abstract:
Provided are: a liquid crystal member comprising a liquid crystal layer having a non-flat surface, wherein desired optical characteristics are obtained in the liquid crystal member; and a millimeter wave modulation element. The present invention is provided with a liquid crystal layer formed by polymerizing, in an aligned state, a liquid crystal composition including a polymerization initiator and a liquid crystal compound having a polymerizable group, the liquid crystal compound having magnetic susceptibility anisotropy, at least one main surface from among the two main surfaces on both ends in the thickness direction of the liquid crystal layer being a non-flat surface having any of a recessed shape, a projecting shape, and an uneven shape, the angles of the slow axes of the liquid crystal compound with respect to the adjacent non-flat surface in a region on the non-flat-surface side of one of the two main surfaces being equal, and the slow axes of the liquid crystal compound being parallel to each other in a region on the other main surface side.
