Abstract
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.
