ABSTRACT:
This invention provides a liquid suspending medium for an electrophoretic image display and/or recording device, comprising as a main component an oligomer of 1,1,2-trifluoro-2-chloro-ethylene expressed by ##STR1## where n is 2 or 3, and each of X.sub.1 and X.sub.2 is Cl or F. The use of this oligomer facilitates gravity adjustment between the liquid suspending medium and electrophoretic particles, and results in a liquid suspending medium highly suitable for an electrophoretic image display and/or recording device.
