Patent ID: 7965040

Claim:
A plasma display panel, comprising: a front substrate and a back substrate facing each other across a discharge space; a plurality of row electrode pairs each extending in a row direction and arranged in column direction on a rear-facing face of the front substrate, each of the row electrode pairs being constituted of a pair of row electrodes facing each other across a discharge gap; a plurality of column electrodes each extending in the column direction and arranged in the row direction on a face of the back substrate facing the front substrate, and forming unit light emission areas in the discharge space in positions respectively corresponding to intersections with the row electrode pairs; and phosphor layers respectively provided in the unit light emission areas for emitting light of different colors, wherein each of the column electrodes has widened portions of a row-direction width larger than that of the other portions, and each of the widened portions faces a head portion of one of the pair of row electrodes constituting each row electrode pair, the head portion facing the other row electrode with the discharge gap in between, the widened portion of the column electrode, that faces the unit light emission area of the unit light emission areas in which the phosphor layer emitting light of a required color is provided, is located in a different position in the column direction of the head portion of one of the corresponding row electrode pair facing the other row electrode with the discharge gap in between from a position of another widened portion of another column electrode facing another unit light emission area in which the phosphor layer is provided for emitting light of a different color from the required color; and wherein a column-direction width of the widened portion of the column electrode facing the unit light emission area in which the phosphor layer emitting the light of the required color is provided is larger than a column-direction width of the widened portion of the column electrode facing the unit light emission area in which the phosphor layer emitting the light of a different color from the required color is provided.
