Abstract
UV curable coatings containing dual phase filler-polymer compositions with high resistivity, low dielectric constant, good optical density, and controlled electrical resistivity are described, and cured coatings or films formed thereof, along with their use in black matrix, black column spacers, and other light shielding coating elements in LCD. Devices having these black matrices, black column spacers, and/or other light shielding coating elements, and methods of preparing and making these various materials and products are also described.
