Title:
LIQUID CRYSTAL ELECTROOPTICAL DEVICE
Document Type and Number:
Japanese Patent JPS62239122
Kind Code:
A
Abstract:

PURPOSE: To obtain the titled device capable of obtaining a light-on and a light-off simultaneously with an electric field having a one direction within an one picture element by exciting two ranges having different normal directions of a ferroelectric liquid crystal layer within the one picture element.

CONSTITUTION: The normal directions of the liquid crystal layer in between the range 3 of left half part and the range 4 of right half part of the titled device which is used, for example, as spectacles of a stereotelevision is delayed by 35°. The uniform orientation ranges which have the normal direction of the liquid crystal layer at a position clock-wisely delayed from a rubbing direction by about 13° observing from each polyimide film sides are formed at a left eye range 3 and a right eye range 4 respectively by the injected liquid crystal, by the effect of rubbing treatment on the polyimide film, and the effect of transferring a phase of the liquid crystal from cholesteric state to smectic state. The light-off in the titled device in which the polarizing plates 7, 8 are provided at the entrance and exit sides of a light of the cell respectively is obtd. in case that the direction of the molecular orientation of the liquid crystal accords with the polarizing axis 8 of the one side of the polarizing plate, and the light-on of the prescribed device is obtd. in case that the direction of the molecular orientation of the liquid crystal is counter-clockwisely delayed from the polarizing axis 8 by 35°.
