Title:
POLYMER DISPERSION-TYPE LIQUID CRYSTAL FILM, AND METHOD FOR PRODUCING POLYMER DISPERSION-TYPE LIQUID CRYSTAL FILM
Document Type and Number:
WIPO Patent Application WO/2023/189891
Kind Code:
A1
Abstract:
Through the present invention, there is provided a polymer dispersion-type liquid crystal film that takes on a different appearance in each desired region using a polymer dispersion-type liquid crystal layer that is capable of switching between a transparent state and a scattering state in only a prescribed region. This polymer dispersion-type liquid crystal film 100 includes an electroconductive transparent substrate 10, a polymer dispersion-type liquid crystal layer 20 including a polymer matrix 22 and liquid crystal droplets 24 dispersed in the polymer matrix, and an electroconductive reflecting substrate 30 in the stated order, and has, in plan view, a first region A and a second region B which differ from each other in the amount of change in glossiness due to application of a voltage, the amount of change in glossiness due to application of a voltage in the first region A being less than the amount of change in the second region B, and the liquid crystal droplets 24 in the first region A including a non-polymerizable liquid crystal compound 24a and a liquid crystal polymer 24c.
