The present invention relates to a plasma display device, and more particularly, to a plasma display device formed by drawing two kinds of electrodes to one side of a substrate.

In general, the plasma display apparatus generates a plasma by gas discharge and displays the image using the plasma (Plasma Display Panel, hereinafter referred to as 'PDP'), a chassis base supporting the PDP, and It includes a plurality of driving boards mounted on the opposite side of the chassis base PDP and connected to electrodes located inside the PDP through a flexible printed circuit and a connector.

The PDP seals a front substrate including an X electrode, a Y electrode, and an M electrode disposed between the two electrodes on the same plane, and a rear substrate including an address electrode spaced vertically and spaced apart therefrom. Then, there is a four-electrode PDP formed by filling a discharge gas between the two substrates.

The four-electrode PDP selects a discharge cell to be turned on by an address discharge occurring between the M electrode and the address electrode by the scan pulse of the M electrode and the address pulse of the address electrode, and then, while the sustain pulse is biased to the M electrode, The sustain pulses applied to the Y electrodes alternately cause a short gap discharge between the M electrode and the X electrode or the Y electrode closer thereto, followed by a long gap discharge between the X electrode and the Y electrode, thereby displaying an image.

Unlike the three-electrode PDP, which does not include the M electrode, the four-electrode PDP allows the X electrode and the Y electrode to be provided on the partition wall by further providing the M electrode, thereby providing an opaque electrode (the bus electrode of the X and Y electrodes). By minimizing the blocking of visible light, the X electrode and the Y electrode are provided at the outermost side of the discharge cell to induce long gap discharge to increase the excitation area of the phosphor by vacuum ultraviolet rays, thereby improving luminous efficiency.

For this reason, the Y FPC 33a and the M FPC 34a are disposed at positions shifted from each other on one side of the PDP 10, and are not interfering with each other, rather than the Y driving board 33 and the M driving board 34. It can be easily connected.

As another example, referring to FIG. 5, the electrode terminal group Y _{t1 to} Y _tn formed at the front end of the Y electrodes Y1 to Yn is formed in a straight line to the front end of the front substrate 11 to form a Y FPC 33a. ) and remains connected to, the group electrode terminals formed at the front end of the M electrode (M1~Mn) (M _t1 ~M _tn) is more electrode terminal group (Y _t1 ~Y _tn) of the Y electrode (Y1~Yn) It is formed inside the front substrate 11 and is connected to the M FPC 34a. Therefore, the Y FPC 33a and the M FPC 34a are arranged in an overlapped state.
