Plasma display device is a flat panel display device that displays images by using discharge phenomenon. It has excellent display capability such as display capacity, brightness, contrast, afterimage, and viewing angle. It is attracting attention as a display device that can do it.

Referring to FIG. 1, the plasma display apparatus 10 includes a plasma display panel 20 and a chassis member 40. The plasma display panel is formed by injecting and encapsulating a discharge gas into a discharge cell formed between the front substrate 21 and the rear substrate 22, and charging the discharge gas by applying a voltage between the electrodes crossing the discharge cell. Visible light is emitted by excitation of the phosphor by ultraviolet rays generated by causing discharge in the discharge cells thus formed, thereby realizing an image.

In addition, in order to prevent the occurrence of electromagnetic interference (EMI) in the connecting cable 80, the connecting cable 80 that interconnects the circuit boards 50 need to be fixed to the cable fixing device.

Conventionally, such a cable anchoring device is used to wind the connecting cable using a tape 60 as shown in FIG. 1, or, although not shown, by installing a bracket on the chassis member 40, the bracket connects the connecting cable. To be fixed. However, when the tape 60 is used, there is a problem in that a process of winding the connecting cable with tape is more difficult and it is difficult to securely fix the tape 60. When the bracket is used, the chassis member is made of a metal material so that the bracket is connected with the chassis member. It is difficult to manufacture integrally, and as a result, there is a problem that a separate bracket must be installed in the chassis member.

The present invention has been made to solve the above problems and other problems, the connection cable of the chassis member for a display device having a structure that can be fixed simply and stably the connection cable for electrically connecting between the circuit boards It is an object of the present invention to provide a fixed structure and a plasma display device having the same.

In addition, another object of the present invention is to provide a connection cable fixing structure of a chassis member having a chassis member suitable for thinning and reducing weight and manufacturing cost, and a plasma display apparatus having the same.
