Patent ID: 8362680

Claim:
A plasma display panel comprising: a front panel; and a back panel, wherein the front panel and the back panel are disposed facing each other, and peripheries of the front panel and the back panel are sealed to form a discharge space, the front panel has display electrodes, a dielectric layer, and a protective layer on a front substrate, the back panel has electrodes, barrier ribs, and a phosphor layer on a back substrate, wherein the display electrodes and the dielectric layer of the front panel are configured such that, in a graph in which an area percentage of the display electrodes in an area of an image display region of the front panel is expressed by a longitudinal axis, and a difference between a coefficient of expansion of the front substrate from room temperature to 300° C. and a coefficient of expansion of the dielectric layer from room temperature to 300° C. is expressed by a lateral axis, the area percentage and the difference between the coefficients of expansion stay within a region formed by connecting coordinates (35×10 −7 /° C., 60%), coordinates (8×10 −7 /° C., 60%), coordinates (5×10 −7 /° C., 40%), and coordinates (23×10 −7 /° C., 40%) in the mentioned order with a straight line where the straight line is included, wherein a content of MoO 3 in the dielectric layer is 0.3 mol % or more and 2 mol % or less.
