PCT No. PCT/JP95/02696 Sec. 371 Date Aug. 27, 1996 Sec. 102(e) Date Aug. 27, 1996 PCT Filed Dec. 26, 1995 PCT Pub. No. WO96/20425 PCT Pub. Date Jul. 4, 1996A polymer dispersed liquid crystal display device includes a top substrate and a bottom substrate. First electrodes are provided on the top substrate and second electrodes are provided on the bottom substrate. Orientation are provided on the top and the bottom substrates. The orientation films are respectively rubbed in predetermined directions. A polymer material, a liquid crystal material and a predetermined amount of a chiral agent are interposed between the top and bottom substrates. The polymer material is separated from the liquid crystal material through irradiation by ultraviolet rays. The liquid crystal material and polymer material have a mutually orientated and dispersed structure. The liquid crystal material has a predetermined twisting angle in a predetermined twist direction. As a result, light is scattered when substantially normal to the liquid crystal display device and the surface of the top substrate. Thus, a polymer dispersed liquid crystal display device is obtained that is particularly bright in a specific direction.
