Abstract
An electrophoretic display according to an exemplary embodiment of the present invention may include: a first substrate, a first electrode formed on the first substrate, a second electrode spaced apart from the first electrode, a second substrate facing the first substrate, and a plurality of charged particles arranged between the first substrate and the second substrate, pairs of the charged particles having different polarities. Each charged particle has at least two threshold voltages, where the threshold voltages are voltage magnitudes below which a voltage applied across the first and second electrodes does not move the associated charged particle. The pixels may represent any one of colors such as red, green, blue, white, and black by including two charged particles of different colors in one pixel and changing the attractive and repulsive force threshold voltages of each of two charged particles of different colors contained in the pixel.
