ABSTRACT:
A pair of substrates both having electrodes are arranged to oppose each other and bonded via a sealing member. A liquid crystal/polymer composite film is formed inside this structure, and color filters of red, green, and blue are formed on one of the two substrates. This liquid crystal/polymer composite film consists of liquid crystal domains and a polymer. The liquid crystal domains are so formed that regions corresponding to the color filters of different colors have an essentially equal optical effect on light components having the respective transmission wavelength bends of these color filters. The polymer is formed by polymerizing a photosetting polymeric material. To form the liquid crystal/polymer composite film having the optical effects for the individual color filters, a polymer dispersed liquid crystal display device with this arrangement is manufactured by radiating light for polymerizing the polymeric material onto a solution mixture of the liquid crystal and the polymeric material while adjusting the intensity of the light in each region corresponding to one of the color filters.
