A display for displaying variable and permanent data. It has two support plates 1 and 2 which form between themselves a chamber 3 in which a fluid which can be switched between optically different states is arranged. Polarizers are arranged on the sides of the support plates 1 and 2 which face away from the chamber 3. In the region of permanent data, transparent elements 14 are present between the support plates 1 and 2. Furthermore, a source of light 15 is arranged on the side of the cell facing away from the observer. The variable data consists of bright data against a dark background. The observer's side of the cell is provided with a light-impervious layer 8 which has cutouts 9 and 10 in the region of the variable data as well as in correspondence with the permanent data. A transflective layer is disposed in the cutput region to enable viewing the cutout region and permanent data via incident light.
An instrument panel, in particular for a display in a motor vehicle, with a sheet-like carrier (7) on which colors have been applied for representing a scale and/or characters and/or symbols as well as for covering the regions outside the contours of the scale, characters or symbols. The colors of the scale, characters or symbols comprise a system of layers (13) formed by a plurality of transparent color layers of different coloration fully or partially covering over one another.
A display device has a reverse polarity LCD panel separated from a cavity by a light diffuser. A plurality of LEDs mounted in said cavity are interconnected to a common constant current source.
