Plasma display panel and manufacturing method thereof

摘要

A plasma display panel includes a pair of substrates and spacers. On one of the substrates, closed-type barrier ribs for dividing a discharge space into respective cells are formed. The one of the substrates is aligned face to face with the other substrate. The peripheral portion of the substrates is sealed by a sealing material that is softened by applying heat thereto. The spacers are softened at a temperature higher than the softening temperature of the sealing material at the time of applying heat during sealing the substrates and used for bonding top portions of the barrier ribs and the other substrate to each other. The spacers are placed between the top portion of the barrier ribs formed on the one of the substrates and the other substrate.
