Patent ID: 7153176

Claim:
A method for manufacturing a plasma display panel in which a front substrate having row electrodes and a rear substrate having column electrodes extending in a direction intersecting said row electrodes are arranged with a grid-shaped ribs being interposed between said front substrate and said rear substrate in a manner in which said front substrate and said rear substrate face each other, said method comprising: a step of forming said grid-shaped ribs using a mask having a pattern corresponding to a shape of said grid-shaped ribs, said pattern having a plurality of first stripes extending in a row direction and a plurality of second stripes extending in a column direction so as to cross each other at intersections, wherein each of said first stripes is reduced in width around said intersections while said second stripes all have the same width along their lengths so that four cuts are formed around each of said intersections and each of said cuts is defined by the width-reduced part of each of said first stripes and each of said second stripes.
