The present application relates to the technical field of electrophoretic particles, more particularly to an electrophoretic particle, a preparation method therefor, and an application thereof. Provided is an electrophoretic particle. The electrophoretic particle includes a shell layer and a core layer, which is wrapped in the shell layer. The core layer includes a plurality of core particles, and the density of the core particles is lower than a density of the shell layer. The electrophoretic particle includes the shell layer and the core layer wrapped in the shell layer, the core layer includes the plurality of core particles, and the structure of the plurality of the core particles makes the shell layer wrapping on surfaces of the plurality of the core particles form a
folded structure, thus increasing a surface area of the core layer and improving the bonding tightness between the shell layer and the core layer, and making the shell layer of the resulting electrophoretic particle have relatively strong tightness. Based on this, an overall particle size of each electrophoretic particle can be appropriately reduced, the moving velocity of the electrophoretic particle under the action of the
electric field can be improved, and it is ensured such electrophoretic particle will never have the light leakage problem, thereby improving the excellent performance of a device.
