Abstract

A display apparatus for use in motor vehicle for displaying measured values, functions status and disturbance indications, and the like comprising at least one liquid crystal cell having areas (A, B) with different coloration of the indications. In order to enable a flexible coloration for individual coloring which can be changed or switched at any time, the areas (A, B) with different coloration of indications on the back of a surface of a transmission liquid crystal cell are separated from one another by light shafts in which light sources with corresponding different colors are arranged. The colored light of one light source for one area (A) is screened by a partition from the other area (B) of the liquid crystal cell (FIG. 1).
