This invention relates to a display apparatus for alphanumeric displays having a display panel. A controllable light source illuminates a bundle of optical fibers and in which one switch element is triggerable from a control line. The switch element is introduced into each light path leading from an optical fiber to a display element, and with the switch element the associated light path can be selectively opened or blocked. A multi-color representation of the displays is attained by each display element of the display panel having a variable number of light paths. The display elements are disposed in the same variable number of internested matrices. The optical fibers associated with one matrix are joined into bundles and are illuminated by separate light sources. The control lines of the switch elements are individually triggerable for the various matrices with a control unit in order to represent the variable number of alphanumeric displays or a multi- color alphanumeric displays simultaneously, where in the latter case filters are connected to the output side of the light sources or optical fibers.
