Abstract
A liquid for electrophoretic display which makes it possible to display a black color having a low reflectance or a color having a high color saturation and a white color having a high reflectance and display them at high contrast and which inhibits coagulation of white fine particles and is excellent in stability can be prepared by using a liquid for electrophoretic display containing at least white fine particles, resin particles colored by a dye and/or a pigment and a liquid phase dispersion medium, wherein fine particles in which a difference in a refractive index from the liquid phase dispersion medium is 0 to 0.05 are contained and have an average particle diameter of 50 to 500 nm. The electrophoretic display device of the present invention is prepared by filling the liquid for electrophoretic display between a pair of substrates, and the electronic device of the present invention is characterized by mounting therein the electrophoretic display device.
