A device for displaying variable and fixed indicia is provided by liquid crystal cells which give variable as well as fixed information. The variable and fixed information is in the form of alpha and/or numerical characters and/or punctuation characters, such as colons in a digital clock. The fixed characters are formed by members such as spacers which simultaneously space two carrier plates relative to one another as part of a liquid crystal cell. In a preferred embodiment, the display is a so-called twisted nematic display with spacers consisting of a glass solder enriched with a spacer element. The invention may be used in all types of displays having a relatively low tolerance of plate spacing and which contain fixed characters. It is particularly suited for liquid crystal displays in measuring equipment such, for example, as tachometers or watches.
