ABSTRACT:
A plasma display apparatus includes a conductive rear surface cover covering a rear surface of a plasma display panel; an optical filter provided with a conductive layer having a surface resistance of 0.5 Ω/square or above, which is disposed at the front surface of the plasma display panel and serves to reduce leakage of electromagnetic waves from the plasma display panel; an optical filter fixing member electrically connected with the rear surface cover, for at least retaining the optical filter; and a conductive body having elasticity, which is interposed between the optical filter and the optical filter fixing member. A plurality of bosses are formed in the optical filter fixing member. A part of the elastic conductive body is compressed by the bosses and connection resistance with the elastic conductive body is reduced.
