The invention relates to a plastic film with an interference multilayer system applied thereon that comprises at least two layers. Said layers can be obtained by hardening and/or applying thermal treatment to a coating composition containing nanoscale inorganic solid particles having polymerizable and/or polycondensable organic surface groups, thereby forming a layer that is crosslinked by means of the polymerizable and/or polycondensable organic surface groups. The films can be used as an optical laminating film.

Nanocomposite material for the production of index of refraction gradient films

An optical film composed by laminating a light scattering filmscattering and transmitting light and comprising at least two phases or more different in refractive index and a reflective polarizerselectively P/S converting the light. It is preferred that at least one phase of the light scattering film larger in the refractive index has a columnar structure extending in the thickness direction of the film and the transmittance of the film in the normal direction is 4% or more. The optical film is excellent in visibility, is small in light loss in order to provide an excellently visible and bright image, and has an excellent light collecting property when used in a liquid crystal display device or the like.

A liquid crystal display device utilizing a ferroelectric liquid crystal, e.g., a chiral smectic liquid crystal aligned to establish two bi-stable display states. The display device is driven in a time-sharing mode. The change of the bi-stable display states is effected by applying a selected voltage to the changed ferro-electric liquid crystal. Thereafter the display state is held by applying an A.C. pulse voltage.
