Abstract

A liquid crystal display device according to the present invention includes a pair of opposing substrates and polymer dispersed liquid crystal interposed between the pair of opposing substrates, the polymer dispersed liquid crystal including a polymer matrix and a plurality of liquid crystal droplets partitioned by the polymer matrix. The polymer matrix and the plurality of liquid crystal droplets are formed by applying light and/or heat to a polymer dispersed liquid crystal precursor in which a polymer for forming the polymer matrix and liquid crystal molecules for forming the liquid crystal droplets are combined via a combining group, the combining group being cleaved by the application of light and/or heat.
