摘要： A pair of transparent substrates are arranged to oppose each other and bonded to each other through a seal member. A polymer dispersed liquid crystal layer and spacers are provided between the pair of transparent substrates. A plurality of pixel electrodes respectively provided with TFTs are disposed in a matrix form on the counter surface of one substrate opposing the other substrate, and the spacers for regulating the gap between the substrates are fixed, through resin films, to remaining regions of the counter surface of one substrate obtained by excluding pixel regions corresponding to the pixel electrodes from the region inside the seal member. A black mask is formed on the remaining regions of the counter surface of the other transparent substrate, and a flat counter electrode opposing the plurality of pixel electrodes is formed on the black mask. The polymer dispersed liquid crystal display device is obtained by injecting, into a cell in a vacuum state, a solution mixture of a photo-setting polymeric material and a liquid crystal material that are mixed in a formulating proportion not less than a solubility at a normal temperature and a normal pressure, increasing the temperature of the solution mixture to a temperature not less than the soluble limit temperature of the liquid crystal, and thereafter photo-setting the photo-setting polymeric material.
