ABSTRACT:
An electrophoretic display includes a first substrate disposed on a viewer side, a second substrate disposed at a predetermined spacing with the first substrate, a first electrode disposed on the first substrate side, a second electrode disposed on the second electrode side, liquid disposed at the predetermined spacing, and a plurality of charged particles dispersed in the liquid. The charged particles are movable by changing a polarity of a voltage applied between the first and second electrodes to effect display. The second electrode at a pixel has a surface area larger than that of the first electrode at the pixel.
