Concealing particles for electrophoretic display device, display particle dispersion for electrophoretic display device, electrophoretic display medium, and electrophoretic display device

摘要

PROBLEM TO BE SOLVED: To provide a concealment particle for an electrophoretic display device which suppresses deterioration of drive property of an electrophoresis particle.SOLUTION: A concealment particle for an electrophoretic display device has a volume average particle diameter of 300 nm to 1,000 nm and a CV (Coefficient of Variation) value of 15% or less (for example, reflection particle group 36).
