PROBLEM TO BE SOLVED: To suppress the radiation of high-frequency disturbance of a plasma display. SOLUTION: A ground terminal of a panel driving circuit printed board 1 and a metal plate 3 for panel heat radiation are electrically connected with a setscrew 9 without using an insulation holder and doughnut type ferrite bead cores 13 are arranged so as to surround the setscrew 9 to fix the metal plate 3 for panel heat radiation and panel driving circuit printed board 1 and also make a DC current and a low-frequency current flow at the same time while cutting off a high-frequency current, thereby deterring the panel 2 of a PDP and the metal plate 3 for panel heat radiation from serving as an antenna for high-frequency disturbance. Consequently, while the operation of a driving circuit is held stable, a PDP television for beautiful video can be provided. COPYRIGHT: (C)2003,JPO
