ABSTRACT:
A liquid crystal device comprises a pair of substrates each having an electrode on one side thereof and a liquid crystal layer filled in a space between the paired substrates wherein the paired substrates, respectively, have, on a side contacting the liquid crystal layer, a pattern embossed layer which is made of a material having a refractive index relative to an ordinary ray substantially equal to that of a liquid crystal in the liquid crystal layer. The pattern embossed layers of the respective substrates are so arranged as being fitted with each other when contacted with each other. The method for making such a device as set out above is also described along with a liquid crystal device having irregularities formed on a pair of substrates. The irregularities are made of a material whose dielectric constant is substantially equal to that of the liquid crystal substance used.
