A largely transparent cabinet or case in which an exhibitor can place one or more objects so that viewers may see them. Much as frames both set off and protect two-dimensional works, vitrines are display furniture, designed to set apart and to protect their contents. Most are effectively boxes whose sides are panels of clear glass or plastic. Some are also fitted with lamps providing artificial light. Some have sensors that can trigger alarms. And some are outfitted to maintain a desirable atmosphere. There are very small vitrines, even for single objects, but some three-dimensional objects might be better displayed in a shadow box.(pr. və-TREEN)
