Abstract

A display system comprising at least one display element, for example in the form of a pivoted pointer for indication of a changing measured value in association with a scale. The display element is implemented by an electro-optical cell filled with a liquid, the cell having two transparent plates separated by a distance frame with an associated illuminating device at the back side. Portions of one of the transparent plates is rendered opaque, the remaining areas on that plate providing transparent windows. Transparent areas are also provided between the plates. One of said transparent areas has a contour corresponding with the contour of the scale. The other of said areas extends over a larger surface.
