Abstract:
A polymer dispersion type liquid crystal display element comprising:a pair of substrates; an electrode formed on an opposite surface of each of the substrates; polymers; liquid crystal droplets; and a polymer-liquid crystal complex held between the pair of substrates, the polymer-liquid crystal complex comprising the polymers and the liquid crystal droplets dispersed in the polymers, wherein (1) liquid crystal molecules in the liquid crystal droplets are oriented in a direction substantially parallel to the substrates and oriented randomly in a plane parallel to the substrates and (2) the liquid crystal droplets are deformed until the deformation rate of the liquid crystal droplets is substantially equal to a deformation rate at which the transmittance shows a minimum value in a deformation rate-transmission curve showing the change in transmittance during light scattering versus the change in deformation rate of the liquid crystal droplets, whereby the liquid crystal molecules in the liquid crystal droplets are oriented in a direction substantially parallel to the substrates and oriented randomly in a plane parallel to the substrates.
