A modular display device for optical signals includes a supporting frame and a plurality of display modules each having a module housing and a plurality of light emitting diodes integrated therein. The module housings are inserted into the supporting frame and are releasably attached thereto. The attachment of the module housings in the supporting frame is implemented by movable snap-in locking members that are structured for engaging respective holding elements disposed on at least two opposing side walls of each module housing. The snap-in locking members of adjacent side walls of different module housings are arranged to be offset with respect to each other.
