1. A process for forming an electrophoretic display, comprising the steps of:
- a) dispersing a sealing composition in an electrophoretic fluid comprising charged pigment particles dispersed in a dielectric solvent,b) filling display cells with the electrophoretic fluid and the sealing composition,c) separating the sealing composition from the electrophoretic fluid and forming a supernatant layer on top of the electrophoretic fluid, andd) sealing the filled display cells by interfacial polymerization while the sealing composition is on top of the electrophoretic fluid.
