Abstract
A plasma display panel is provided that can prevent interference of discharge between rows securely without reducing operation margin. Plural partitions being at a distance from each other define a discharge space of each column in the screen. The column space defined by the partitions is narrowed periodically along the column direction. A surface discharge gap is formed at each enlarging portion of the column space. A pair of plural main electrodes is provided for surface discharge. Each of the main electrodes includes a belt-like bus portion extending in the row direction of the screen and plural gap forming portions protruding in the column direction from the bus portion toward the enlarging portion in each column space.
