Method for manufacturing plasma display panel and laser head exposer used therefor

A method of manufacturing a plasma display panel, comprising:

• providing a first plate,
• providing a second plate,
• providing address electrodes, barrier ribs, sustain electrodes and scan electrodes defining discharge cells between the first and second plates, and
• joining the first plate and second plates to each other at their edges, with the discharge cells there between
• wherein at least one of providing address electrodes, barrier ribs, sustain electrodes and scan electrodes includes:
• forming a material layer on a substrate;
• directly exposing the material layer while scanning in a first direction using a laser head exposer, the laser head exposer including a first adjustment region, an exposing region and a second adjustment region arranged along a second direction, perpendicular to the first direction;
• shifting, after directly exposing, the laser head exposer in the second direction;
• and
• repeating the directly exposing in a direction parallel to the first direction,
• wherein a portion of the material layer exposed by one of the first and second adjustment regions during a previous directly exposing is exposed by the other of the first and second adjusting region during a subsequent directly exposing.
