Patent ID: 7491107

Claim:
A method of manufacturing a plasma display panel, wherein: a structure of the plasma display panel is formed with photolithography; at least one of a display electrode, a black layer, an address electrode or a partition wall of the structures of the plasma display panel, in a process of forming the structure, is exposed using a plurality of photomasks with a same pattern and a different aperture width of an exposure part, with a different amount of exposure, an exposure amount radiated from the light source when the exposure is made by a photomask with a longer aperture width is larger than an exposure amount radiated from the light source when the exposure is made by a photomask with a shorter aperture width, wherein the exposure amount is determined by exposure intensity or exposure time; and a portion of the at least one of the display electrode, the black layer, the address electrode or the partition wall exposed by the photomask with the longer aperture width is also exposed by the photomask with the shorter aperture width.
