Member for displaying projected image and projection system

Abstract

Provided is a member for displaying a projected image, including: a first base material; a second base material; and an optical member, in which at least one optical member is disposed on a surface of the first base material or the second base material, the optical member includes a plurality of cholesteric liquid crystal dots, the cholesteric liquid crystal dot is formed of a liquid crystal material having a cholesteric structure, the cholesteric structure imparts a striped pattern formed of bright portions and dark portions in a cross-sectional image of the cholesteric liquid crystal dot taken by a scanning electron microscope in a direction perpendicular to a substrate, the dot includes a portion where the height thereof successively increases to the maximum height thereof from an end portion toward the center thereof, an angle between a normal line with respect to a line formed by the first dark portion from the surface of the dot on a side opposite to the substrate and a line representing the surface of the is in a range of 70° to 90° in this portion of the cross-sectional image, and a reflection center wavelength of the dot is in a range of 400 to 1000 nm.
