Abstract

A plasma display device is disclosed. In one embodiment, the plasma display device includes a plasma display panel, a chassis base, a printed circuit board assembly, and a flexible printed circuit. The chassis base supports the plasma display panel. The printed circuit board assembly is disposed at one side of the chassis base. The flexible printed circuit electrically connects an electrode of the plasma display panel and the printed circuit board assembly. The flexible printed circuit crosses an extension plane of the printed circuit board assembly at a predetermined angle and is connected to the printed circuit board assembly. One embodiment of the invention lowers manufacturing costs and reduces EMI by shortening a length of a flexible printed circuit.
