えて高輝度を得ることができる。First, when a voltage pulse is applied between the display cathode 13a and the auxiliary anode 11a, a minute discharge is generated in a designated pixel, and the charged particles sequentially move to the adjacent auxiliary discharge region through the charged particle passage 17. At this time, if information (voltage) is written (applied) along the display anode 15a, display discharge is likely to occur only in the pixel selected by the priming effect. Therefore, since the time required for discharging is shortened, the number of voltage pulses that can be applied per unit time is increased, and high brightness can be obtained.
また、表示放電が背面ガラス基板10上に形成された表示
陽極15aと表示陰極13aとの間で面放電形態と成るので、
カラ−PDP場合、前面ガラス基板20の内面に塗布された
蛍光体層方向に放電するとき、スパッタリングが起こら
なくて蛍光体層の寿命の極大化ができる。Further, since the display discharge is in the form of surface discharge between the display anode 15a and the display cathode 13a formed on the rear glass substrate 10,
In the case of the color PDP, when discharging in the direction of the phosphor layer coated on the inner surface of the front glass substrate 20, sputtering does not occur and the life of the phosphor layer can be maximized.

いので有効可視面積が広くなって、光透過率を極大化さ
せることができる。Further, according to the present invention, since all the electrode groups are formed on one substrate, the manufacturing process is simplified so that the production cost is low, and at the same time, since there is no electrode on the front glass substrate 20, the effective visible area is widened. Thus, the light transmittance can be maximized.

放電領域とが隔離され、互いに異なる領域で放電が発こ
るので誤放電の危険を減少させることができる。Further, the light due to the auxiliary discharge between the display cathode 13a and the auxiliary anode 11a is blocked by the light shielding plate 14 ', so that the light does not leak. Since it is used to generate photoelectrons, it produces the most abundant production of charged particles and also increases the brightness ratio. The light-shielding plate 14 'separates the auxiliary discharge area and the display discharge area from each other, and discharges occur in different areas, so that the risk of erroneous discharge can be reduced.
