Ferroelectric liquid crystals can be regarded to be a multi-functional material exhibiting the charge carrier transport as an organic semiconductor and the remnant polarization as a ferroelectric material simultaneously. According to this point of view, we have investigated the electrical properties at the interface of a polarized liquid crystal and the electrode surface, and found significantly enhanced charge inject at the interface, resulting in space charge limited current at the a vey low electric field of 104V/cm. We also applied it to enhance charge injaection for organic light emitting diodes.
