A method of driving an information display panel: in which display media constituted by particles including charged particles are sealed between two substrates, at least one substrate being transparent; in which the display media, to which an electrostatic field is applied, are made to move so as to display an information image; and in which, after an erasing wherein a color is displayed on a whole screen is performed, a rewriting of an information display is performed in such a manner that a color at the erasing is changed by applying a voltage forming electrostatic field in a reverse direction as that at the erasing, is characterized in that, after the rewriting of the information display is finished, a voltage forming electrostatic field in the same direction as that at erasing is applied. Thereby, providing a method of driving an information display panel, in which the particles constituting the display media are not stuck and disable to the substrate if information such as an image is left for a long time as it is, and a previous display image does not remain when a new display image is to be displayed after a long time left, and to provide an information display panel.

Liquid crystal composite materials containing organic compounds enable the lowering of the drive voltage of liquid crystal display devices and of liquid crystal display devices of a polymer-dispersion type. The liquid crystal composite materials can be used in liquid crystal display devices and PDLC devices with a scattering layer having a liquid crystal and a polymer between the electrodes. A ter phenyl derivative can also favorably be used in the liquid crystal composite materials and in the liquid crystal display devices.

A 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.
