DP is a glass substrate 11 on the display surface H side, a pair of display electrodes X and Y for surface discharge corresponding to each display line, a dielectric layer 17 covering the display electrodes X and Y, a protective film 18, a back surface side. Glass substrate 21, address electrodes A orthogonal to the display electrodes X and Y, and stripe-shaped partition walls 2 parallel to the address electrodes A.

定されている。The internal discharge space 30 is divided by the barrier ribs 29 in the extension direction of the display electrodes X and Y for each unit light emitting region EU, and the gap size thereof is defined to be about 100 to 150 μm.

及びガラス基板１１を透過して外部へ射出する。The phosphor 28 is formed on the glass substrate 2 on the side opposite to the display electrodes X and Y in order to avoid ion bombardment due to surface discharge.
It is provided between the barrier ribs 29 on the upper part of the first partition and is excited by ultraviolet rays generated by surface discharge to emit light. The light emitted from the surface of the phosphor 28 (the surface in contact with the discharge space) is the dielectric layer 17
And, it passes through the glass substrate 11 and is emitted to the outside.

成される。Since the display electrodes X and Y are arranged on the display surface H side with respect to the phosphor 28 that emits the display light, the width of the display electrodes X and Y is wide in order to widen the surface discharge and minimize the shielding of the display light. It is composed of a wide band-shaped transparent conductive film 41 and a narrow band-shaped metal film (bus electrode) 42 overlapping one end side thereof. Since the transparent conductive film 41 has a relatively high resistance, the metal film 42 is provided to supplement the conductivity of the display electrodes X and Y in the line direction. Usually, the transparent conductive film 41 and the metal film 42 are each formed by a photolithography method.

荷蓄積状態が形成される。In the display, first, for example, as writing on the entire display surface H, a voltage exceeding the discharge start voltage is applied to one of the display electrodes X for all lines so that each unit light emitting area EU in each line. Simultaneous surface discharge (dielectric layer 1
Discharge in the surface direction 7). When the surface discharge occurs, wall charges having a polarity opposite to the applied voltage are accumulated in the dielectric layer 17 on each display electrode X, Y. Next, in a state where a discharge sustaining voltage lower than the discharge starting voltage is applied to the other display electrode Y,
A predetermined voltage is applied to the address electrode A selected according to the display pattern to generate the address discharge between the display electrode Y and the address electrode A. An appropriate charge storage state is formed by the address discharge.

整される。After that, a discharge sustaining voltage is alternately applied to the display electrodes X and Y of each line. As a result, strong light emission occurs each time the discharge sustaining voltage is applied in the unit light emitting region EU in which a predetermined amount of wall charges are accumulated. At this time, the brightness is adjusted by appropriately selecting the application period of the discharge sustaining voltage.

間の放電は生じない。At the time of writing, the address electrode A is set to the ground potential, and the relative potential difference between the display electrode X and the address electrode A has the same value as the potential difference between the display electrodes X and Y. Becomes However, since the gap size of the discharge space 30 is large, normally only the surface discharge between the display electrodes X and Y occurs as described above, and the discharge between the display electrode X and the address electrode A does not occur.

There is a problem that the electrode A and the drive circuit may be damaged.

幅は８０μｍ程度である。Since the display electrodes X and Y are arranged on the display surface H side with respect to the discharge space 30 as described above, they are composed of the transparent conductive film 41 and the metal film 42 which complements the conductivity thereof. . The transparent conductive film 41 is formed of a Nesa film (tin oxide film) having a thickness of about 2000 Å, and its width is about 120 μm. The metal film 42 is, for example, a thin film having a thickness of about 1 μm and having a three-layer structure of chromium-copper-chrome, and its width is about 80 μm.

平面形状は直線状とされている。In the PDP 1, as shown in FIG. 2, the metal film 42 of the display electrode Y is continuously formed along the line direction in the same manner as the conventional transparent conductive film 41.
It is formed so as to overlap with. That is, the planar shape of the metal film 42 is linear.

The metal film 42 of the display electrode X overlaps the outer end portion of the transparent conductive film 41 between the address electrodes A, similarly to the display electrode Y,
In other portions, the plane shape is selected so as to avoid the upper surface of the transparent conductive film 41 and detour to the outside.

による。At this time, bubbles may occur at the interface between the transparent conductive film 41 and the metal film 42, but no bubbles occur at the interface between the glass substrate 11 and the metal film 42. This is because the adhesion between the glass substrate (soda lime glass) 11 and the metal film 42 (chrome layer) is extremely good.

As in the conventional case, a write voltage is applied to one of the display electrodes X to generate surface discharge on the entire display surface H, and an address discharge is selectively generated between the display electrode Y and the address electrode A to form a display pattern. Then, the sustain voltage is alternately applied to the display electrodes X and Y for a certain period thereafter to maintain the display state of one pattern. Then, such an operation is repeated to display a moving image or the like.

Since no bubbles exist and there are no bubbles that make the film quality non-uniform, if the discharge conditions such as the gap size of the discharge space 30 are appropriately selected, the display electrode X and the address electrode A can be formed.
There is no unnecessary discharge between and.

Compared with the case where the film 42 is divided, the resistance value of the display electrode X in the line direction can be reduced and the driving efficiency can be improved.

The discharge can be suppressed. That is, the opposite discharge through the discharge space 30 is more likely to occur as the facing area of the electrode is larger. Therefore, the metal film 42 is the transparent conductive film 41.
Since the width is narrower and the area facing the address electrode A is smaller than that of, the discharge is induced between the metal film 42 and the address electrode A even if a burr occurs on the metal film 42 separated from the transparent conductive film 41. Hateful.
