摘要： A display device comprising a light guide (12), a front plate (14), and an intermediate electromechanically operable foil (16). Two electrode layers (22, 23) are arranged on either side of the foil (16) to induce electrostatic forces on the foil (16) and to bring selected portions of the foil into contact with the light guide (12), thereby extracting light from the light guide (12). The second electrode layer (22) is arranged on the opposite side of the light guide (12) with reference to the foil (16), and separated from the light guide (12) by means of a refractive layer (28). As no electrode layer is required on the light guide itself, the light path of rays extracted from the light guide is cleaner, and the absorption of light is reduced. The light guide can have a thickness such that the light extracted from the light guide per unit length is sufficient to allow for line-at-a-time addressing.
