An electrophoretic display device includes: a substrate; partition walls which partition a space on the substrate into a plurality of cells; an electrophoretic dispersion liquid with which the plurality of cells on the substrate is filled; a sealing film which is disposed so as to face the substrate with the partition walls interposed therebetween and seals the plurality of cells; and phase separation portions which are partially formed between upper surfaces of the partition walls and the sealing film and in which the electrophoretic dispersion liquid is subjected to phase separation.
