Abstract

A new method for achievement of a uniform liquid crystal alignment in conventional sandwich cells is proposed. The method is based on the interaction between a highly anisotropic liquid crystal thermoset material, used as an aligning layer, and liquid crystal. An important advantage of the method is that the contact surface of the alignment layer with the liquid crystal, contrary to the conventional aligning techniques using buffed polymer films, is not subjected to any mechanical treatment before the cell assembling and thus being entirely defect-free. The alignment layers based on anisotropic liquid crystal thermosets are especially important in the case of ferroelectric liquid crystal devices where the surface defects are playing a crucial role.
