Zusammenfassung:	The invention relates to a display device (10) comprising a light guide (2) and a plate (4), which extend essentially parallel in a mutually spaced relationship, said display device further comprising a movable element (3) which is arranged between the light guide and the plate in a spaced relationship to the light guide, selection means (5, 6) to locally bring said movable element into contact with the light guide, and a number of spacing elements (13)arranged on the light guide or the plate for maintaining the space between the movable element and the light guide and the plate, respectively, characterized in that the spacing elements form an integral part of the movable element. The invention also relates to a method of producing the display device according to the invention. L'invention concerne un dispositif d'affichage (10) comprenant un guide de lumière (2) et une plaque (4) qui s'étendent de façon sensiblement parallèle, à distance l'un de l'autre. Ce dispositif d'affichage comprend par ailleurs un élément mobile (3) disposé entre le guide de lumière et la plaque à distance du guide de lumière, des moyens de sélection (5, 6) permettant de mettre cet élément mobile en contact localement avec le guide de lumière, ainsi qu'un certain nombre d'éléments d'espacement (13) disposés sur le guide de lumière ou sur la plaque pour maintenir un espace entre l'élément mobile et le guide d'onde et entre l'élément mobile et la plaque, ces éléments d'espacement faisant partie intégrante de l'élément mobile. L'invention concerne en outre un procédé de production d'un tel dispositif d'affichage.
