To provide a favorable electro-optic displays, and methods for driving the same.SOLUTION: A display 600 comprises a layer 610 of electro-optic material with first and second electrodes on opposed sides thereof. One or both electrodes have at least two spaced contacts, and voltage control means 626 is arranged to vary the potential difference between the two spaced contacts attached to the same electrode. A display comprises a layer of electro-optic material with a sequence of at least three electrodes (612-624) adjacent thereto. Voltage control means vary the potential difference between the first electrode 612 and the last electrode 624 of the sequence. The electrodes of the sequence of electrodes alternate between the two surfaces of the layer of electro-optic material, and have edges which overlap with or lie adjacent to the preceding and following electrodes of the sequence of electrodes. The electrodes, other than the first and last, are electrically isolated such that the potential thereof is controlled by passage of current through the layer of electro-optic material.SELECTED DRAWING: Figure 6 【課題】好適な電気光学ディスプレイおよびその駆動方法を提供する。【解決手段】ディスプレイ６００は第１および第２の電極をその両側に伴う電気光学材料の層６１０を備え、一方または両方の電極は少なくとも２つの間隔を置かれた接点を有し、電圧制御手段６２６は同一電極に取り付けられた２つの間隔を置かれた接点間の電位差を変動させるために配置される。ディスプレイはそこに隣接する一連の少なくとも３つの電極（６１２−６２４）を伴う電気光学材料の層を備える。電圧制御手段は一連の電極のうちの最初の電極６１２と最後の電極６２４との間の電位差を変動させる。一連の電極のうちの電極は電気光学材料の層の２つの表面間で交互し、一連の電極のうちの先行および後続電極と重複するかまたはそれに隣接してある縁を有する。電極は最初および最後以外その電位が電気光学材料の層を通る電流の移動によって制御されるように電気的に絶縁される。【選択図】図６
