ABSTRACT:
The plasma display apparatus has a noise filter circuit with a noise filter connected to an AC supply disposed at the back side of a plasma display panel. The plasma display apparatus also has a back cover composed of a magnetic metal material disposed at the back side of the plasma display panel to cover the noise filter circuit, wherein magnetic lines of force in a core, made of magnetic material and including the noise filter direct approximately identical to the in-plane direction of the back cover. The configuration can eliminate audible noises because the amount of leakage flux passing through the back cover is reduced.
