Title: Dynamically scattering type liquid crystal display element
Inventor: TAKEI TOSHIRO
IPC: G02F1/137
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To provide a dynamically scattering type liquid crystal display element which enables dynamic driving with a high duty ratio. SOLUTION: Liquid crystal 13 having a high dielectric constant and showing a positive dielectric anisotropy is sealed, by being twisted, between substrates 11, 12 on which electrodes 22, 31 are formed. The interaction between liquid crystal molecules is strong. because the liquid crystal 13 is twisted. Consequently, when the applied voltage of the liquid crystal 13 is gradually raised, the oriented state in accordance with orientation treatment is maintained up to a certain constant level (threshold value), and when the applied voltage exceeds the threshold value, turbulence of the liquid crystal molecules abruptly occurs due to current, thus creating the dynamically scattered state. Further, when the applied voltage is being lowered, the oriented state of the liquid crystal is sharply changed at the threshold value.  Accordingly, the change of the transmissivity characteristic against the applied voltage becomes sharp, thus enabling dynamic driving with a high duty ratio.
