Abstract: A display element and a display device in which the display element is mounted. The display may be a variable message sign. The sign includes a tube-like housing in which lenses and apertures can be disposed. The light exiting a light source is emitted via an emitting surface, by way of which an illuminated traffic sign results from interacting with further display elements.

The optical axes can thereby extend horizontally, or the optical elements can lie on a main axis which is tilted downward in an radiation direction. In both cases, sunlight impinging from above at an angle advantageously falls on the LED to a slight degree, by way of which the phantom light phenomenon is minimized.
