A device for displaying at least one pictogram inside a vehicle passenger compartment. The device includes a light source suitable for emitting light in response to a control signal, and an opaque covering layer having a through opening defining the pictogram. A photosensitive layer extends facing or in the opening. When the light source is deactivated, the photosensitive layer is opaque and has the same color as the covering layer. When the light source is activated, the photosensitive layer reacts so as to render the pictogram defined by the opening of the covering layer visible for an occupant of the vehicle passenger compartment.
