Display apparatus suggesting a movement of the displayed objects and having an open front casing of which the front is closed off by a first transparent plate successively coated on the inside surface with a transparent dark layer and a semi-transparent white layer. A second transparent plate spaced at a slight distance behind the first plate bears a picture in the shape of surfaces coated with transparent colored layers and surrounded by an opaque layer serving as a background. The picture consists of a fixed portion which is permanently displayed and at least two portions which are alternately displayed. A plurality of light sources arranged with the casing behind the second plate each illuminate one of the portions and are screened with respect to each other by partitions. The light sources associated with the alternately displayed portions are alternately actuated by a program switch.
