The display cabinet, made to display silver and porcelain collections, appears at the end of the 18th C during the reign of Louis XVI. It is a small, sober cupboard with one or two glazed doors and glazed sides. It sometimes has a mirror back and often a pierced gallery on the top. The 19th C display cabinets are often more lavish, in the Louis XV style with painted decoration or in Vernis Martin. The 20th C Art Deco style display cabinet, also called a glass cabinet or china cabinet, is usually in walnut veneer, with mirror back and glass shelves. It can be either rectangular or completely round.
