    摘要: The invention provides a stress display member including: a selective reflection layer, in which the selective reflection layer includes cholesteric liquid crystal layers that are obtained by curing a liquid crystal composition including a polymerizable liquid crystal compound, and the selective reflection layer is a layer that selectively reflects circularly polarized light having any one sense of right-handed circularly polarized light and left-handed circularly polarized light in a specific wavelength, a stress display member further including a birefringence layer and optionally including a circularly polarized light separating layer, and a strain measurement method that is performed by using any one of the stress display member. According to the stress display member of the invention, it is possible to measure and visually observe a strain that occurs in a target having a large surface area at a low cost and measure a strain with high measuring accuracy.
