Abstract:
A plasma display panel comprising:a first substrate serving as a display surface; a second substrate opposed to said first substrate with a discharge space interposed therebetween, said discharge space having a plurality of unit discharge regions arranged in matrix; a first electrode and a second electrode formed on a main surface of said first substrates on the side of said discharge space, being paired with each other and provided for each row of said plurality of unit discharge regions; a third electrode formed on a main surface of said second substrate on the side of said discharge space, being provided for each column of said plurality of unit discharge regions; and phosphors of two kinds or more formed on said main surface of said second substrate covering said third electrode, having different luminescent colors, wherein said first electrode comprises: a trunk portion extending in a first direction, which is a direction of said row; and branch portions connected to said trunk portion, being provided for said plurality of unit discharge regions, respectively, and protruding in a second direction which is a direction of said column, wherein said second electrode comprises: a trunk portion extending in said first direction; and branch portions connected to said trunk portion of said second electrode, being provided for said plurality of unit discharge regions, respectively, and protruding in said second direction to define discharge gaps between said branch portions of said first and second electrodes, respectively, wherein the areas of said branch portions of said first electrode vary among said plurality of unit discharge regions, and wherein the areas of said branch portions of said second electrode are equal among said plurality of unit discharge regions.
