PLASMA DISPLAY PANEL AND MANUFACTURING METHOD THEREOF

摘要

A plasma display panel is provided with a front substrate (22); a rear substrate (23) arranged to face the front substrate; and an exhaust tube (21). A discharge space is formed by sealing the circumference of the front substrate with the circumference of the rear substrate. The exhaust tube is connected to the rear substrate for exhausting the discharge space and filling the discharge space with a discharge gas. The exhaust tube is formed of a lead-free glass, and the ratio of its thickness to its outer diameter is 0.2 or more.
