Polymer-dispersed-type liquid crystal film, emulsion, and method for producing polymer-dispersed-type liquid crystal film

Abstract

According to the present invention, provided is a PDLC film, which includes a PDLC layer excellent in thickness uniformity and is suppressed from causing liquid crystal leakage from the PDLC layer. A method of producing a polymer dispersed liquid crystal film of the present invention includes: applying, to a first transparent conductive film, an emulsion including a solvent, and polymer particles and liquid crystal particles dispersed in the solvent to form an applied layer; drying the applied layer to form a polymer dispersed liquid crystal layer containing a polymer matrix and the liquid crystal particles dispersed in the polymer matrix; and laminating a second transparent conductive film on the polymer dispersed liquid crystal layer, wherein the polymer particles include first polymer particles and second polymer particles, and wherein an average particle diameter of the second polymer particles is larger than an average particle diameter of the first polymer particles.
