The spontaneous polarization and rotational viscosity of the c-director of the ferroelectric liquid crystal 4-octyloxy-biphenyl4-carboxylic acid 4-(1-methyl-heptyloxy)-phenyl ester at various pressures were investigated. Spontaneous polarization as a function of T -TCAp) decreased markedly when pressure was changed from 0.1 to 20 MPa and was independent of pressure as pressure was further increased. Rotational viscosity decreased when pressure was applied. These results suggest that the conformation of liquid crystal molecules changes at pressures below 20 MPa. © 2008 The Japan Society of Applied Physics;
