Is a flat display device including a pair of substrates provided with components such as electrodes as is well known. A surface discharge type PDP includes a pair of main electrodes serving as an anode and a cathode in a discharge for securing luminance. This is a PDP that is arranged in parallel on the same substrate and configured to generate surface discharge along the substrate surface. Although a structure in which the main discharge is shared between adjacent lines is also known, basically, a pair of main electrodes is arranged for each line, and the total number is 2n (n is the number of lines). In the surface discharge type PDP, the phosphor layer for color display is provided on the other substrate opposite to the substrate provided with the main electrode, so that deterioration of the phosphor layer due to ion bombardment during discharge can be reduced. it can. An arrangement in which the phosphor layer is arranged on the substrate on the back side is called "reflection type", and an arrangement in which the phosphor layer is arranged on the substrate on the front side is called "transmission type". For higher luminance, a reflection type in which the front surface of the phosphor layer is a light emitting surface is advantageous.

The conductivity of transparent conductive materials such as TO and Nesa is insufficient for practical use. Therefore, in the surface discharge type PDP, a laminated body of a transparent conductive film and a metal film that supplements conductivity is used as a main electrode.

圧降下と、それに伴う印加電圧の低下を招き、画面全体
での発光輝度の低下と、放電の不安定化が発生する。In a conventional PDP, a bus electrode in a main electrode pair supplies a current required for discharging a plurality of discharge cells on the main electrode pair. For this reason, as the screen size of the PDP increases and the length of the main electrode pair increases accordingly, the current flowing through the bus electrode increases, and the voltage drop due to the electrical resistance of the bus electrode and the resulting applied voltage As a result, the luminance of the entire screen is reduced, and the discharge becomes unstable.

示内容によって発光輝度のばらつきが発生してしまう。Further, as the number of discharge cells on one main electrode pair increases due to the enlargement of the screen of the PDP, the difference between the case where the number of discharge cells to emit light is large and the case where the number of discharge cells is small increases. Therefore, in the case of a display in which the number of discharge cells to emit light on one main electrode pair is large, the voltage drop due to discharge is large compared to the display in the case of a small number, and the applied voltage is greatly reduced. Luminance is reduced, and variation in light emission luminance occurs depending on display contents.

放電セルとの間に放電干渉が発生してしまう。As a method of solving these problems, there is a method of reducing the resistance of the bus electrode by widening the width of the bus electrode. However, when the bus electrode is spread to the slit portion (portion where surface discharge occurs), the bus electrode is enlarged. The light emission of the discharge cells is blocked by the bus electrode portion, so that the aperture ratio, which is the ratio of the light-transmitting portion in the unit light-emitting region, becomes small, and the luminous efficiency decreases. Also, when the bus electrode is extended toward the reverse slit portion (the portion between the main electrode pairs where surface discharge cannot occur), the discharge at the slit portion spreads to the reverse slit portion, and the discharge cell adjacent to the address electrode in the extending direction extends. During this time, discharge interference occurs.
