Abstract: The present invention relates to a portable decorative object including a transparent part including at least one reflective inclined edge oriented so as to receive an incident ambient light perpendicular to an upper face of the transparent part, the inclined edge being oriented so as to send back the perpendicular incident light to inside the transparent part. The object includes a decorative region arranged inside the transparent part, illuminated by the light reflected by the inclined edge.

Abstract: A display device includes at least one wall with transparent areas and a reflecting object arranged inside the display device and oriented so as to receive an incident external light and to redirect a reflected light onto the transparent areas. The transparent areas are provided in different planes and the reflecting object includes several reflecting surfaces or a non-planar reflecting surface to reflect incident light rays on each of the transparent areas along different reflection axes. The display device can advantageously be integrated into a bottle or a bottle cap.
