Abstract

An electrophoretic display has a matrix addressing structure which includes a first support structure 10 on one side of the display and a second support structure 20, substantially parallel to the said first support structure, on the other side of the display. On the inner surface 12 of the first support structure 10 there is a first set of parallel electrodes 11 and on the facing the inner surface 23 of the second support structure 20 there are second 22 and third 21 sets of parallel electrodes arranged substantially orthogonal to the first set of electrodes 11. The electrodes 21,22 of the second and third sets are interspersed with one another.
