In order to eliminate the two-domain texture defects of Ferroelectric Liquid Crystal (FLC)samples(chiral nematic-chiral smectic C(N*-SmC*)) in their phase sequences to be cooled down from the N* phase to the SmC* phase

five kinds of FLC devices were prepared by using a FLC R-2301 and two kinds of liquid crystal alignment films SE-410 and RN-1199. After experiments and tests

it is concluded that the uniform mono-domain alignment of ferroelectric liquid crystals can be obtained by asymmetric boundary anchoring.Furthermore

the alignment textures of five devices were tested by a polarizing optical microscope with the crossed polarizers

and experimental results show that the FLC devices can offer half-V-shaped electric-optical characters and a static contrast ratio in 300∶1 after asymmetric boundary anchoring. The conclusion is in good agreement with the theoretical approximation and can provide a simple and novel method for fabricating ferroelectric liquid crystal devices.
