Abstract: A method of manufacturing opaque electrodes of a plasma display panel includes providing a mold plate having plating grooves corresponding to patterns of the opaque electrodes of the plasma display panel, forming first plating layers in the plating grooves, transferring the first plating layers to display electrodes on a substrate and removing the mold plate, leaving the first plating layers on the display electrodes. There may be adhesive between the display electrodes and the first plating layer. There may be a second plating layer between the display electrode and the first plating layer.

Abstract: A high pressure sodium lamp is provided. The high pressure sodium lamp includes a discharge lamp vessel to the ends of which a pair of electrodes are respectively connected, a sleeve coupled to at least one end of the discharge lamp vessel and connected to one of the electrodes, a wire frame slidably inserted into the sleeve, and a buffer coil, one end of which is connected with the wire frame and the other end of which is housed inside the sleeve, elastically supporting the discharge lamp vessel.
