<p>Disclosed is a plasma display device which is equipped with a plasma display panel which implements a gradation display of images using a sub-field system. The plasma display panel has a protective layer comprising an underlayer formed on top of a dielectric layer, and a plurality of aggregate particles distributed across the complete surface of the underlayer. The plasma display device configures images using right-eye fields which display right-eye image signals and left-eye fields which display left-eye image signals. The right-eye fields and left-eye fields each have a plurality of sub-fields. The initial sub-field has the smallest brightness weighting, the second sub-fields has the largest brightness weighting, and the brightness weighting becomes successively smaller from the third sub-field on.</p>
