A method of producing barrier ribs for a plasma display panel substrate, which comprises the steps of: (a) partially filling a groove portion of a mold with a first photosensitive glass-ceramic paste selected from a photosensitive black glass-ceramic paste and a photosensitive white glass-ceramic paste, and curing the paste by irradiating with radiation; (b) supplying a second photosensitive glass-ceramic paste, which is different from the first photosensitive glass-ceramic paste, selected from the photosensitive black glass-ceramic paste and the photosensitive white glass-ceramic paste, on a glass base, and laminating the mold with the glass base through the second paste to form a laminate; (c) irradiating the laminate with radiation to form a rib precursor molded article composed of two white and black layers; (d) removing the mold from the glass base and the rib precursor molded article to transfer the rib precursor molded article to the glass base; and (e) sintering the rib precursor molded article to form a rib formed integrally on the glass base.
