ABSTRACT:
An alignment mark for a plasma display panel (PDP). The alignment mark comprises a first and a second alignment patterns installed on a front and a rear substrate respectively. The second alignment pattern on the non-display area is simultaneously formed with the rib barrier formation on the display area of the rear substrate, wherein the second alignment pattern is hexagonal-honeycomb. The first alignment pattern on the front substrate is simultaneously formed with the non-transparent material fabrication, such as a bus electrode or black matrix fabrication, and corresponds to a space within the second alignment pattern. The first alignment pattern comprises at least one line segment, parallel to at least one side of the hexagonal honeycomb pattern on the rear substrate with a predetermined distance therebetween.
