摘要： There are provided an electromagnetic shielding sheet and a plasma display apparatus. The electromagnetic shielding sheet includes a base sheet; a first sheet including first and second patterns formed in directions crossing each other on a first surface of the base sheet; and a second sheet including a third pattern formed on a second surface of the base sheet. The first and second patterns include a conductive material, the third pattern includes a light absorbing material, and at least one of the first and second patterns is grounded. Accordingly, conductive patterns for shielding electromagnetic waves and blocking external light are formed on a first surface of a base sheet, and patterns for blocking external light are formed on a second surface of the base sheet, so that the functions of shielding electromagnetic waves and blocking external light can be simultaneously performed using one sheet, and therefore, the ambient contrast ratio of a display image can be enhanced without increasing manufacturing costs. Further, patterns for shielding electromagnetic waves are directly formed a glass member of a filter or an upper substrate of the panel, so that processes of forming an electromagnetic shielding sheet can be easily performed.
