PROBLEM TO BE SOLVED: To simplify a construction and drive and to greatly increase plasma density by providing a circular loop at a pixel position drawn by at least one of plural electrodes which form a pixel by crossing and facing each other, and making it a loop electrode applied with AC. SOLUTION: A plasma display element is equipped with an electrode 1 forming a circular loop part 2 at each pixel position, which is not a perfect circle but is nearly of anΩ-shape. When AC I is applied to the electrode 1, magnetic flux is generated around the loop part 2 in the circumferential direction to form a magnetic field B. Since the electrode 1 is formed on either one of base plates, at least 1/2 of magnetic flux in the magnetic field B passes through a discharge space, and a discharge gas in the discharge space is charged and ionized so as to generate a plasma. Since all the energy supplied in the AC, except for part such as eddy current, is transferred to ionization energy of the discharge gas, discharging with high efficiency to possible.
