<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device of a high contrast ratio and a high response speed, which enables a liquid crystal layer to form a stable transparent state and can obtain black display excellent in viewing angle characteristics in liquid crystal display. <P>SOLUTION: The liquid crystal display device is composed by forming an electrode and the liquid crystal layer between substrates. The liquid crystal layer is composed of a liquid crystal material including liquid crystal molecules and particulates, is optically isotropic when an application voltage to the electrode is lower than a threshold, and is optically changed by the change of the array of the liquid crystal molecules when the application voltage is the threshold or higher. The particulates have been surface-treated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
