In order to make it possible to be adapted to be used for an integrated liquid crystal panel having a built-in direct touch-entry enabling device, a liquid crystal material made by dispersing many needle-shaped magnetic substance particles respectively coated with a surface active agent in a well known liquid crystal substance and a method of making the same. The liquid material can be utilized in the form of many encapsulated liquid material units combined with one another. In case such encapsulated liquid crystal material is used for a liquid crystal device, it need not be sealed with glass or the like and can be directly applied to paint any required part and, even if the painted part is curved during the use, it can develop its performance.
A liquid crystal material comprising a liquid crystal substance to be used to form a liquid crystal display device and many needle-shaped magnetic substance particles dispersed in said liquid crystal substance and coated respectively with a surface active agent.
A liquid crystal material consisting of many microcapsules combined with one another and respectively containing therein a liquid crystal substance to be used to form a liquid crystal display device and many needle-shaped magnetic substance particles dispersed in said liquid crystal substance and coated respectively with a surface active agent.
A method of producing a liquid crystal material comprising a first step of preparing many needle-shaped magnetic substance particles, a second step of treating said respective magnetic substance particles on the surfaces with a surface active agent to orient the molecules of a liquid crystal substance so that their long axes may be vertical to the surfaces of said magnetic substance crystals, to prevent said magnetic substance particles from cohering and to uniformly and stably disperse said magnetic substance particles in the liquid crystal substance to be used to form a liquid crystal display device, a third step of dispersing many needle-shaped magnetic substance particles obtained by said second step in a solvent affinable with said liquid crystal substance, a fourth step of mixing the resulant obtained by the third step into said liquid crystal substance and a fifth step of volatilizing and removing said solvent from the mixture obtained by the fourth step to uniformly and stably mix and retain said magnetic substance particles in said liquid crystal substance.
