ABSTRACT:
A method for the manufacture of a ferroelectric liquid crystal cell which includes ferroelectric liquid crystal sealed between a pair of opposed but spaced plates, each having formed on one surface a pattern of conductive layer, the plates being disposed with their conductive layers facing each other, comprises the step of rubbing the surfaces of the plates in at least two directions prior to the sealing of the ferroelectric liquid crystal.
