Abstract
Two-layer structures of a nematic liquid crystal were experimentally studied in cells with interfacial polycarbonate surfaces under orientational transitions from planar- and homeotropic-domain configurations to the homogeneous homeotropic state. Director reorientation was initiated by electric or magnetic fields. The effective order parameter was used to describe the liquid crystal alignment in two-layer structure. Comparison with a model based on the elasticity theory of liquid crystals was carried out.

Keywords: nematic, polycarbonate, two-layer structure, electric field, magnetic field, domain
