Abstract

A liquid crystal display device ( ) comprises two transparent substrates ( ) which are joined to each other via a sealing member ( ) so as to form a gap therebetween, and a liquid crystal layer ( ) which is sealed in the gap and formed of a polymer dispersion liquid crystal or polymer network liquid crystal. There are provided barriers ( ) in the vicinity of both ends of a side ( ) of each seal ( ) between the transparent substrates ( ) where the pouring port ( ) is provided, for preventing the liquid crystal material from turning around into terminal areas ( ) when the liquid crystal material is poured from the poring hole ( ) into the gap ( ), wherein an adhesive force between the barriers ( ) and at least one of the transparent substrates ( ) is weaker than that between the seal ( ) and the transparent substrate. As a result, the terminal areas ( ) are prevented from being insulated from and covered with the liquid crystal material and the transparent substrates ( ) are prevented from being broken when they are cut, thereby improving a fabricating yield.
