Abstract
A plasmonic display device is provided with liquid crystal dipole molecule control. The device is made from a first set of electrodes including at least one electrically conductive top electrode and at least one electrically conductive bottom electrode capable of generating a first electric field in a first direction. A second set of electrodes, including an electrically conductive right electrode and an electrically conductive left electrode, is capable of generating a second electric field in a second first direction. A dielectric layer overlies the bottom electrode, made from a liquid crystal material with molecules having dipoles responsive to an electric field. A plasmonic layer, including a plurality of discrete plasmonic particles, is interposed between the first and second set of electrodes and in contact with the dielectric layer. In one aspect, the plasmonic layer is embedded in the dielectric layer.
