PURPOSE: A ventilator of a plasma display panel is provided to achieve improved yield rate by increasing accuracy of bending angle of the ventilating pipe, while preventing occurrence of crack. CONSTITUTION: A ventilator of a plasma display panel comprises a plasma display panel(70) formed by joining an upper plate(32) and a lower plate(34); a ventilating hole(44) formed at the lower substrate; a ventilating pipe(40) connected to the ventilating hole, and which is shaped as a straight line; and a ventilating/injecting pipe(42) connected to the ventilating pipe, and which ventilates/injects gas and is shaped as a curve. The ventilating/injecting pipe has a bending angle of 90 degree±0.5 degree. |
