The purpose is to provide a polymer dispersion type liquid crystal display panel wherein both a high contrast and a low driving voltage are obtained and scattering performance is superior. n The polymer dispersion type liquid crystal display panel comprises a pair of substrates 10, 11, a polymer dispersion type liquid crystal layer 12 comprising a liquid crystal 18 and a liquid crystalline polymer 17, a driving electrode 7 and an opposite electrode 8. The driving electrode 7 and the opposite electrode 8 are formed on the lower substrate 11, and an electric field is applied approximately in parallel with the above-mentioned lower substrate 11. Under no application of voltage, the above-mentioned liquid crystal 18 and the polymer 17 adjacent to the liquid crystal, which composes an interface, are aligned in approximately the same direction on a plane parallel with the substrates according to an alignment treatment of the substrates, and thereby a transparent state is obtained. Under an application of voltage, the liquid crystal 18 rotates on a plane parallel with the substrates, and the polymer 17 and the liquid crystal 18 are made a disposition state of forming angles on a plane parallel with the substrates, and thereby a scattering state is obtained. |
