1. A display device comprising:
- a light guide;
a movable element; and
selection means to locally bring the movable element into contact with the light guide,wherein the selection means comprise transparent electrodes and, in operation, the movable element, provided that it is in contact with the light guide, contacts the light guide at the location of an electrode, thus causing light to be emitted through the transparent electrode.

Abstract
A display device comprises a light guide and a movable element. By locally exerting a force on the movable element by means of selection means, optical contact between the movable element and the light guide can be brought about. Light emanates from the display device at the locations where optical contact takes place. Measures are taken to employ the force exerted by the selection means as efficiently as possible. This can be achieved by making the force act at the location where the optical contact takes place and/or by reducing other adhesive forces (caused, inter alia, by differences in pressure, static charging, surface stresses, van der Waals'"'"' forces and/or chemical forces).

8. A display device comprising:
-
a light guide; a movable element; and selection means to locally bring the movable element into contact with the light guide; wherein the movable element is situated in an evacuated space below 0.1 atmosphere, and wherein the selection means includes transparent electrodes and, in operation, the movable element, provided that it is in contact with the light guide, contacts the light guide at the location of an electrode, thus causing light to be emitted through the transparent electrode.
