20090146567PLASMA DISPLAY PANEL AND METHOD OF MANUFACTURING THE SAME - A PDP (Plasma Display Panel) comprising a front substrate structure (first substrate structure) in which two pairs of an X electrode and a Y electrode and a non-emission area therebetween are formed, and a plurality of light-shielding films formed with spacing from the X electrode and the Y electrode in the non-emission area. The light-shielding film contains a metal material common with a metal material forming the X electrode and the Y electrode.

20090195157Plasma display device - A plasma display panel and a base chassis differ in thermal expansion coefficient due to the difference of their materials. Similarly, a circuit substrate and the base chassis differ in the thermal expansion coefficient. Since an ADM has a connection terminal portion fixed to the circuit substrate and a radiator plate fixed to the base chassis, the displacement occurs at the high temperature, and an electrode contact failure at the ADM connection terminal portion occurs. Accordingly, in the present invention, the radiator plate of the ADM is flexibly fixed to the base chassis by an elastic double-faced tape having sufficient flexibility, thereby reducing the displacement of the circuit substrate and the ADM due to the thermal expansion and preventing the displacement at the ADM connection terminal portion. Further, the ADM and the base chassis are electrically connected by a soft gasket, thereby preventing the noise generation on the ADM.08-06-2009
