Filed: 1986-04-30
Abstract: PURPOSE:To uniform an initial orientation state and to obtain the bistability provided to a ferroelectric liquid crystal by using an orientation film structure obtained by a rubbing treatment wherein cloth used for rubbing and the strength of the rubbing are asymmetrical between a couple of cells. CONSTITUTION:Orientation films 8 and 8 of the same kind are used for upper and lower substrates 1 and 1 and the cloth used for the rubbing treatment and the pressure at the time of the rubbing are difference between both substrates 1 and 1.
