Abstract
Disclosed is a method of fabricating barrier ribs in a plasma display panel using photosensitive glass powder includes the steps of preparing photosensitive glass powder by reducing a photosensitive glass material to fine powder, putting the photosensitive glass powder or the photosensitive glass powder mixed with a UV-ray transmitting organic material in a mold, aligning a photomask over the photosensitive glass powder and carrying out exposure thereon, carrying out first and second thermal treatment on the photosensitive glass powder so as to generate different crystalline phases at exposed and non-exposed portions, respectively, and forming barrier ribs by etching the portion where the crystalline phase is generated.
