FERROELECTRIC LIQUID CRYSTAL ELEMENT

摘要

PURPOSE:To increase the quantity of transmittance light by setting a tilt angle imparted by a pulse voltage impression at the angle larger than the tilt angle when the pulse voltage impression is not executed. CONSTITUTION:The ferroelectric liquid crystal of a ferroelectric liquid crystal element disposed with the ferroelectric liquid crystal having two stable molecular arrangement states between a pair of substrates 11 and 11' has the tile angle theta1 (2theta1; the angle between the two optical main axes corresponding to the two stable molecular arrangement states after the pulse voltage impression) imparted by the pulse voltage impression. The relation theta1>theta2 is held between the tilt angle theta1 and the tilt angle theta2 (2theta2; the angle between the two optical main axes corresponding to the two stable molecular arrangement states when the pulse voltage impression is not executed) when the pulse voltage impression is not executed. The certain specified bistable state is thereby attained with good productivity. The display element or high-speed shutter element having high responsiveness, high picture element density and large area is realized by combining the specified stable state and polarizers.
