Abstract
The present invention is directed to an electrophoretic dispersion, in particular, an electrophoretic dispersion comprising uncharged or lightly charged additive particles for improving bistability of an electrophoretic display. The average diameter of the additive particles is about 1% to about 25% of the average hydrodynamic diameter of the charged pigment particles.
