| abstract |
A liquid crystal composition exhibits a ferroelectric phase and a chiral nematic phase at a temperature above that of the ferroelectric phase. The pitch of the natural helix of the chiral nematic phase is at least four times as great as the pitch of the natural helix of the ferroelectric phase. The pitch of the ferroelectric phase is thus sufficiently short to ensure that the liquid crystal has a helical structure when placed between the electrode plates of an electro-optical device while the nematic pitch is sufficiently long to facilitate alignment of the liquid crystal layer. The natural pitch of the ferroelectric phase is preferably less than one tenth of the distance between the electrode plates and the pitch of the nematic phase is preferably eight times the distance between the electrode plates. |
