ABSTRACT:
A particle movement type display device includes a plurality of pixels each of which is constituted by a first substrate and a second substrate disposed opposite to each other with a spacing therebetween, charged particles disposed between the first substrate and the second substrate, a first electrode and a second electrode disposed in contact with the spacing. An image is displayed by moving the charged particles under application of an electric field between the first electrode and the second electrode. The first electrode is formed on the first substrate at a part of a portion corresponding to each pixel, and a non-electrode forming portion at which the first electrode is not formed is provided on the first substrate.
