Abstract
Electrophoretic displaying particles are provided. The particle is comprised of a resin and pigment granules enclosed therein. The pigment granules have an average particle size ranging from 0.1 μm to 20 μm, and the granule diameter distribution has two or more frequency maximums. This electrophoretic displaying particulate has high masking performance, improving the displaying contrast of the displaying device.
