Abstract:
1. A method for manufacturing a plasma display panel, comprising: a step for forming barrier ribs on a surface of an insulating substrate in order to separate a plurality of cells from one another; an applying step for applying a phosphor material in the form of paste to each of said cells by covering said surface of said insulating substrate and side surfaces of said ribs with said phosphor material; an inspecting step; and a drying step for drying the phosphor material paste, wherein said inspecting step determines whether an amount of said phosphor material in each of said cells is equal to or less than a predetermined amount based on a size of an area of a surface of said phosphor material that produces a maximum intensity of a reflected light when visible light is radiated onto a whole surface of said phosphor material before said drying step.
