LAMINATED BODY, AND VIRTUAL REALITY DISPLAY DEVICE

WIPO Patent Application WO/2024/070771

A1

The present invention addresses the problem of providing a laminated body which includes two cholesteric liquid crystal layers and in which a cholesteric liquid crystal layer formed by a coating treatment has a high reflective index. The laminated body according to the present invention includes a first cholesteric liquid crystal layer formed using a first composition containing a first liquid crystal compound and a second cholesteric liquid crystal layer formed on the first cholesteric liquid crystal layer and formed by a coating treatment using a second composition containing a second liquid crystal compound, in which the first liquid crystal compound is a disk-like liquid crystal compound, the first liquid crystal compound and the second liquid crystal compound are different from each other, and, when a dark line located at a position farthest from the first cholesteric liquid crystal layer side is defined as a surface-layer dark line and a dark line located at a position closest to an intermediate position in the direction of the thickness of the second cholesteric liquid crystal layer is defined as an intermediate dark line among bright lines and dark lines derived from a cholesteric liquid crystal phase, the ratio of a region width in which the surface-layer dark line is present to the width of the intermediate dark line is 1.2 or less.
