Patent ID: 7504774

Claim:
A plasma display panel comprising: a first substrate; a second substrate disposed substantially parallel to the first substrate; partition walls disposed between the first and second substrates defining discharge cells in which gas discharge occurs; a plurality of phosphor layers, wherein each phosphor layer is disposed in one of the discharge cells and formed by coating any one of red, green, or blue phosphors; and a unit pixel comprising: a plurality of discharge cells; and a plurality of discharge electrodes disposed such that they cross the respective discharge cells positioned in the unit pixel, wherein the area in which the discharge electrodes cross at least one discharge cell is different from the area in which the discharge electrodes cross the remaining discharge cells; and wherein the discharge cells are substantially the same size; and wherein the area in which the discharge electrodes cross the discharge cell in which a blue phosphor layer is formed in the largest among areas in which the discharge electrodes cross the respective discharge cells positions in the unit pixel and wherein each of the discharge electrodes includes bus electrode disposed above the partition walls and at least one transparent electrodes bonded to the bus electrode; and wherein the transparent electrodes have the shape of a ladder formed in each unit pixel and the transparent electrodes in the adjacent unit pixels are electrically connected by the bus electrode but physically separated.
