Abstract: A display medium including a display layer for authenticity identification, wherein the display layer contains a droplet-cured product, and the droplet-cured product contains a resin having cholesteric regularity. The droplet-cured product preferably contains a cured product of a liquid crystal material containing a cholesteric liquid crystal compound. The display layer is preferably a cured product of a coating material containing the droplet-cured product. The display layer may contain plural types of droplet-cured products exhibiting different color tones as the droplet-cured product. The display layer may further contain a metal particle.

Abstract: A circularly polarized light separating film including a resin layer containing a polymer of a polymerizable liquid crystal compound, wherein the polymerizable liquid crystal compound contains a main-chain mesogen and a side-chain mesogen bonded to the main-chain mesogen in a molecule of the polymerizable liquid crystal compound, and the polymer has cholesteric regularity.

Abstract: A multilayer film including: a substrate consisting of a resin that contains a polymer having an alicyclic structure, the substrate having a thickness of not more than 45 ?m; and a resin layer provided on at least one surface of the substrate, the resin layer being formed by curing by irradiation of an active energy ray, wherein: a ratio of the substrate thickness relative to the total of the substrate thickness and the resin thickness is not less than 0.6 and not more than 0.95, and in a temperature range of not less than 30° C. and not more than 90° C., a linear expansion coefficient of the multilayer film is smaller than a linear expansion coefficient of the substrate by 5 ppm/° C. or more.
