There is disclosed a connection structure and method of a plasma display panel that is adaptive for preventing a short circuit caused by conductive ball mass and improving connection cohesiveness. A connection structure of a plasma display panel according to an embodiment of the present invention includes a first substrate having a plurality of panel-electrodes; a second substrate having a plurality of connecting-electrodes arranged to correspond to the panel-electrodes; and a connection member located between the first substrate and the second substrate to directly connect the connecting-electrodes with the panel-electrodes upon compression. Accordingly, there is no conductive ball, so the occurrence of short circuit caused by the conductive ball mass of prior art is prevented and, at the same time, the copper electrode penetrates the panel-electrode, thereby improving connection cohesiveness.
