The polymer-stabilized ferroelectric liquid crystal (PS-FLC) photocured under the application of an AC electric field shows a monostable V-shaped electrooptical characteristics. However, it is not clear how the V-shaped electrooptical characteristics can be realized in the PS-FLC. In this study, we have investigated in detail the elecrooptical characteristics of PS-FLC and the effect of the polymer stabilization on the molecular alignment structure. The electrooptical characteristics and microscopic textures of PS-FLCs, which were photocured under lots of conditions such as the concentration of doped monomer, the frequency of AC electric field and temperature, were measured. Since the existence of domain structure is confirmed in the PS-FLCs, it is guessed that two types of domain, in which there are two alignment directions monostabilized by the mesogenic side chains of polymer photocured under the application of a bipolar square-pulsed AC electric field, would coexist.
