Abstract
In a display device, attached to a plate-type chassis (2) is a PDP (1) having a display screen on which videos are displayed and a circuit board (9) on which a circuit driving the PDP (1) is arranged. The circuit board (9) is shielded with respect to the PDP (1) thanks to the chassis (2), and thus does not receive any unwanted radiation noise radiated by the PDP (1). The display device further includes a back cover (6) and a cabinet (7) each having conductivity. The back cover (6) and the cabinet (7) house therein the PDP (1) and the circuit board (9) attached to the chassis (2). The back cover (6) and the cabinet (7) are both electrically insulated from the chassis (2). Therefore, any unwanted radiation noise from the PDP (1) and the circuit on the circuit board (9) is stopped leaking to the outside.
