Almost only choice by a secondary electron emission layer/protection layer covering the dielectric layer of an AC type PDP has been magnesium oxide (MgO) that is unstable during the production process and difficult to form, thus posing a serious production problem. An AC type PDP constructed such that, instead of covering the surface of a dielectric layer (3) with a dielectric material such as MgO, an insular electrode (4) is made by forming a conductive material such as nickel, aluminum, magnesium and lanthanum hexaboride into an insular shape, and the insular electrode (4) is allowed to capacity-couple with a lower-layer bus electrode (9) by means of an electrostatic capacity formed by a dielectric layer (3) to operate the insular electrode (4) as a sustained electrode.
