Abstract
A liquid crystal display device includes a pair of electrode substrates at least one of which is transparent, a display medium having a liquid crystal region surrounded by a polymer region, and a plurality of pixels. The display medium is interposed between the pair of substrates. A difference between an upper limit value and a lower limit value of a phase transition temperature between a liquid crystal phase and an isotropic liquid phase of a liquid crystal composition constituting the liquid crystal region is 7.0.degree. C. or more.
