The effect of rubbing treatment on molecular orientation is investigated for a vertically aligned ferroelectric LC (VA-FLC) cell having an intergigit electrode to apply an in-plane electric field. The FLC material with a large cone angle (CS-2005 (Chisso Co. Ltd.)) was used since a sufficient high contrast ratio is obtained due to the large effective optical retardation even if the cell thickness is thin. The E-O characteristics were measured for not only normal VA-FLC cells but also polymer-stabilized VA-FLC cells. In the polymer stabilized VA-FLC, the FLC material doped with a small amount of photocurable mesogenic monomers was used. For the VA-FLC cell, it is effective to carry out rubbing treatment on one side of the substrate or both sides of the substrates which are assembled with anti-parallel cell configuration. Half-V shaped T-V characteristics were obtained by implementing polymer-stablization technology.
