Abstract
It is an object of the present invention to provide a liquid crystal display device in which a liquid crystal layer may form a stable transparent state and, in addition, which provides for a black display with an excellent viewing angle characteristic, as well as a high contrast ratio and a high response speed in liquid crystal display. The present invention is directed to a liquid crystal display device comprising an electrode and a liquid crystal layer between substrates, said liquid crystal layer consists of a liquid crystalline material containing liquid crystal molecules and fine particles, and is optically isotropic when the voltage applied to the electrode is lower than a threshold value and undergoes optical transition due to change in the arrangement of the liquid crystal molecules when the applied voltage is not lower than the threshold value.
