Patent ID: 7612490

Claim:
A plasma display apparatus, comprising: a plasma display panel; a conductive rear surface cover covering a rear surface of the 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; wherein a plurality of bosses are formed in the optical filter fixing member, and a part of the elastic conductive body is compressed by the bosses, thereby electrically connecting an electric connection portion of the optical filter with the optical filter fixing member; and wherein K 1 (%) denotes compressibility of the elastic conductive body in an area where no bosses are formed in the fixing member, and K 2 (%) denotes compressibility of the elastic conductive body in an area where the bosses are formed in the fixing member, and a ratio of compressibility of K 1 and K 2 satisfy the following condition: 1 <K 1 /K 2 <2.66.
