Abstract: A display device, in particular in a motor bus, has at least one display field and fasteners for releasably securing the display field in the motor bus. An observation window is arranged at least between the display field and a viewer. In order to make the fastening of the display device less complicated and less expensive and in order to reduce the weight, the dimensions and the costs of the display device at the same time, the fasteners are releasably secured directly to the inner side of the observation window, the inner side facing away from the viewer.
