An electrophoretic display (100) comprises an electrophoretic medium (114) having electrically charged particles disposed in a fluid and capable of moving through the fluid on application of an electric field. An electrode (104, 120) is disposed adjacent the electrophoretic medium and arranged to apply an electric field thereto. A dielectric layer (106, 118) is disposed between the electrophoretic medium (114) and the electrode (104, 120) and has at least one aperture (107, 119) extending therethrough. The provision of the apertures (107, 119) in the dielectric layers enables the dielectric layers (106, 118) to protect the electrodes (104, 120) while reducing electro-optical kickback. When multiple electrodes (104, 120) are present adjacent the electrophoretic medium (114), more than one or all of the electrodes (104, 120) may be provided with apertured dielectric layers (106, 118).

An adhesive composition comprising a polyurethane and a cationic polymeric dopant or a polymerizable cationic dopant may be used to form one or more adhesive layers of electro-optic assemblies. They enable improved electro-optic performance of the corresponding; electro-optic devices even at low temperatures.
