The production of barriers spaced at regular intervals in a color plasma display panel involves coating a frit glass paste of a predetermined thickness on a lower substrate; drying and baking the coated paste to form frit glass and removing the unnecessary portions of the frit glass by using an etchant. The etchant is a dilute acid e.g. sulfuric acid, hydrochloric acid, fluoric acid or nitric acid. |
