Abstract
An electrophoretic display device includes a display element including a pair of first and second substrates which are opposed to each other, and a microcapsule enclosing a display material changed in optical characteristics in response to an electric impulse, the microcapsule being sandwiched between the first and second substrates; and a protective film sealing the display element. In the display device, a first electrode is provided on the surface of the first substrate which faces the second substrate, a second electrode is provided on the surface of the second substrate which faces the first substrate, and a spacer is provided in the space between the periphery of the facing surface of the first substrate and the first electrode.
