Polymer dispersed liquid crystal film

Abstract

Provided is a guest-host polymer dispersed liquid crystal film that can achieve both visual legibility in a transparent state and a shielding property in a scattering state. Provided is a polymer dispersed liquid crystal film, including in the following order: a first transparent conductive film; a polymer dispersed liquid crystal layer; and a second transparent conductive film, wherein the polymer dispersed liquid crystal layer contains: a polymer matrix; and liquid crystal droplets dispersed in the polymer matrix, the liquid crystal droplets each containing a liquid crystal component and a dichroic dye, and wherein when an average particle diameter of the liquid crystal droplets is represented by D (unit: nm), and an inter-droplet distance when the cumulative frequency of the inter-droplet distances accounts for 5% of the cumulative distribution of the inter-droplet distances is represented by R5 (unit: nm), a ratio R5/D is more than 0.10.
