A display case is a cabinet with one or often more transparent tempered glass (or aluminium alloy，plastic） used to display objects for viewing.
A display case may appear in an exhibition, museum, retail store, restaurant, or house. Often, labels are included with the
displayed objects, providing information such as description or prices.
In a museum, the displayed cultural artifacts are normally part of the museum's collection, or are part of a temporary exhibition.
In retail or a restaurant, the items are normally being offered for sale.
