ABSTRACT:
An AC plasma display panel includes a plurality of opaque scanning electrodes (3b, 3c) and maintaining electrodes (4b, 4c) which are parallel to each other, formed on a first glass substrate (1) at the display side of the display, a plurality of ribs (9) formed on a second glass substrate (7) and arranged orthogonally to the scanning and maintaining electrodes, a data electrode (8) formed on the second glass substrate (7), positioned between the ribs and arranged parallel to the ribs (9), wherein a discharge cell (2) is defined by dividing the space between two ribs (9) and includes at least two of the scanning electrodes (3b, 3c) and at least two of the maintaining electrodes (4b, 4c). The maintaining discharge is generated between the two scanning electrodes (3b, 3c) and the two maintaining electrodes (4b, 4c). Consequently, a discharge region can be widened without decreasing the opening ratio, and an AC plasma display panel with high brightness and high efficiency can be obtained. In addition, because the display does not required to use electrodes in which a transparent conductor and a bus electrode are connected electrically, both the number of production steps and the cost of production can be decreased.
