Abstract:
1. A method of manufacturing a plasma display panel that includes forming a plurality of metal electrodes on a substrate in a predetermined direction and forming a first and second dielectric layers on the metal electrodes by firing a glass material, the method comprising: forming the metal electrodes with a film thickness of 4 μm or less, the metal electrodes having a three-layer structure of Cr—Cu—Cr in which a first Cr layer is formed on the substrate, a Cu layer is formed on the first Cr layer, and a second Cr layer is formed on the Cu layer, the Cu layer having a film thickness of 3 μm to 4 μm and each of the first Cr layer and the second Cr layers having a thickness of 500 Å to 2000 Å; placing a first glass material on the substrate, including the metal electrodes; firing the first glass material at a temperature of higher than 600 degrees Celsius and lower or equal to 610 degrees Celsius so that the first dielectric layer is formed having a film thickness of 5 μm to 10 μm; placing a second glass material on the first dielectric layer after the first dielectric layer has been fired; and firing the second glass material at a temperature of 550 degrees Celsius to 560 degrees Celsius so that the second dielectric layer is formed having a film thickness of 10 μm to 15 μm, wherein the first and second dielectric layers are formed with a total film thickness of 20 μm or less by firing a glass paste including a non-lead based glass frit, a binder resin, and a solvent so that bubbles of 10 μm or more in diameter do not exist in the first and second dielectric layers.
