Abstract:
1. A plasma display panel comprising: a pair of substrates opposite each other with a discharge space in between; a plurality of row electrode pairs extending in a row direction and regularly arranged in a column direction on the rear-facing face of one substrate in the pair of substrates to respectively form display lines; a dielectric layer overlaying the row electrode pairs; a plurality of column electrodes extending in the column direction and regularly arranged in the row direction within the dielectric layer, and formed in a different plane from that in which the row electrode pairs are formed within the dielectric layer; unit light-emission areas individually formed in the discharge space in the proximity of intersections of the row electrode pairs and the column electrodes; a partition wall member provided for individually surrounding and defining each of the unit light emission areas; a dividing wall provided for further partitioning each of the unit light emission areas so defined into a first discharge area facing mutually opposing portions of the row electrodes in each row electrode pair and provided for producing a discharge between the row electrodes, and a second discharge area facing a portion of each of the column electrodes opposing a portion of one row electrode in the row electrode pair and provided for producing a discharge between the portion of the column electrode and the portion of the row electrode; and communicating elements each provided between the first discharge area and the second discharge area for communication from the second discharge area to the first discharge area; wherein said partition wall member comprises vertical walls each extending in the column direction to provide a partition between the unit light emission areas located side by side in the row direction, and transverse walls each extending in the row direction to provide a partition between the unit light emission areas located side by side in the column direction, and said dividing wall is in a form extending parallel to the transverse wall between the adjacent vertical walls.
