Abstract

In a gasket and a display apparatus having the gasket, the gasket is interposed between a circuit board and a protective member to transmit electromagnetic waves generated from the circuit board to the protective member. The elastic member separates the circuit board from the protective member. The conductive member surrounds the elastic member and electrically connects the circuit board with the protective member to transmit the electromagnetic waves. The supporting member is provided between the elastic member and the conductive member to support the contact area of the gasket making contact with the circuit board. The adhesive member is provided on the conductive member corresponding to the supporting member to bond the conductive member to the circuit board. Thus, the gasket is not separated from the circuit board, thereby preventing malfunction of the display apparatus.

Claims
