Abstract:
A polymer dispersion type liquid crystal display panel comprising:a pair of substrates at least one of which is transparent; a polymer dispersion type liquid crystal layer composed of a polymer and a liquid crystal, which is held between said pair of substrates; and a first driving electrode and a second driving electrode which are provided at each pixel for applying an electric field to said polymer dispersion type liquid crystal layer and driving the polymer dispersion type liquid crystal layer as a light valve; wherein:said polymer dispersion type liquid crystal layer is a polymer dispersion type liquid crystal layer with a high ratio of the liquid crystal to the polymer having a structure in which the liquid crystal is filled between the substrates and the polymer is dispersed into the filled liquid crystal so that the polymer and the liquid crystal can be aligned according to an alignment treatment of the substrates; said first driving electrode and said second driving electrode are formed on one of said pair of substrates in a disposition state of applying an electric field approximately in parallel with said substrates; and under no application of voltage, said liquid crystal and the polymer, which is adjacent to the liquid crystal and composes an interface, are aligned in an approximately same direction on a plane parallel with the substrates according to an alignment treatment of the substrates as well as under an application of voltage, the liquid crystal rotates on a plane parallel with the substrates and the polymer and the liquid crystal are in a disposition state of making an angle on a plane parallel with the substrates.
