Title:
LIQUID CRYSTAL ELEMENT AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH07253580
Kind Code:
A
Abstract:

PURPOSE: To provide a liquid crystal element which hardly generates a fluctuation of a cell thickness with simple constitution and a device formed by using this element.

CONSTITUTION: This liquid crystal element has substrates 11a, 11b which have a pair of electrodes 12a, 12b facing each other and a chiral smectic liquid crystal 15 which is disposed between a pair of these electrodes and exhibits a state of bistable states. The inside surfaces of the substrates 11a, 11b are so subjected to orientation treatments that the moving direction when the one state of the bistable states is placed under an electric field is the same direction as the moving direction when the other state is placed under the electric field. The orientation treatment of a frame region 32 is varied from the orientation treatment of a display region 31. The same effect is obtd. by improving driving conditions, the oriented films of the frame region and the orientation treatment method.
