In a plasma display panel, 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 difference between the coefficients of expansion and the area percentage 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.
