Abstract

PURPOSE: To make possible erasing in a white turbid state in the portions where voltage application is infeasible in the storage type liquid crystal display element by partially changing the orientation treatment of liquid crystal molecules thereby driving cholesteric liquid crystal.
CONSTITUTION: Transparent substrates 21 provided with transparent electrodes 22 are provided therein with perpendicularly orientation treated layers 23 on the portions where there are the electrodes 22 and horizontally orientation treated layers 24 in the portions where there are no electrodes 22. The abovementioned substrates 21, 21 are opposed at a spacing of about 1W10 times the spiral pitch length of cholesteric phase liquid crystal, between which is then sealed liquid crystal to provide the display element. In the abovementioned element, the white turbid state in the regions 25 near the electrode ends where hitherto white turbidity tends to remain may be erased.
