the art would recognize that a different number of pcb 39 s may be slidingly engaged therewith for example various numbers of pcb 39 s may be slidingly mounted to chassis base 200 via the mounting members according to an embodiment of the present invention a pcb is slidingly mounted to a chassis base and accordingly the number of bosses for mounting the pcb may be reduced therefore the process for mounting a pcb may be simplified and production efficiency of a plasma display device is thereby enhanced in addition since the ground electrode is formed on the surface of a pcb side the contact area between the ground electrode and the pcb is increased and grounding of a pcb is more ensured furthermore a ground electrode of a surface shape may also reduce emi of a pcb a pcb is firmly attached to the chassis because first and second mounting members respectively having first and second guide grooves are attached across and generally parallel to each other and the pcb is inserted along the first and second guide grooves in this case grounding of the pcb may be enhanced since a ground electrode is formed on the pcb such that it contacts each of the guide grooves in particular when the ground electrode is formed along each edge of the pcb grounding is enhanced and emi is reduced.
