example 1
[0080] The first panel 10 was manufactured by the following method. First, an ITO layer is formed on the entire surface of the first substrate 11 of high-strain glass or soda-lime glass, for example, by sputtering. The ITO layer is then patterned in stripes using photolithography and etching, thereby forming pairs of sustain electrodes 12 .
[0081] An aluminum film is then formed, for example, by evaporation, on the entire surface of first substrate 11 so as to cover sustain electrodes 12 . The aluminum film is then patterned by photolithography and etching, whereby bus electrodes 13 are formed on sustain electrodes 12 along one side edge of each sustain electrode 12 . Thereafter, SiO is formed on the entire surface of the first substrate 11 2 Dielectric layer 14 to cover sustain electrodes 12 and bus electrodes 13. Further, a protective layer 15 of magnesium oxide (MgO) was formed to a thickness of 0.6"m on the dielectric layer 14 by electron beam evaporation. In this way...
example 2
[0097] After forming the fluorescent layers 25R, 25G and 25B and firing them in the air at 510° C. for 10 minutes in the furnace, the furnace was evacuated to 1×10 when the temperature in the furnace dropped to 430° C. -2 Pa vacuum degree, and this temperature is maintained continuously for two hours. Other steps were performed in the same manner as in Example 1 to complete the plasma display 2 . In other words, in Example 2, the phosphor firing step and the vacuum firing step were performed in the same furnace. It was confirmed that Example 2 can exhibit the same effects as Example 1.
example 3
[0099] When forming the phosphor layers 25R, 25G and 25B and firing them in an air atmosphere at 510°C for 10 minutes, the air atmosphere in the furnace was replaced with a dry nitrogen atmosphere during the temperature rise until the furnace temperature reached 430°C. Other steps were performed in the same manner as in Example 1 to complete the plasma display 2 . In other words, during the temperature rise in the phosphor firing step, the air atmosphere in the furnace was replaced with a dry nitrogen atmosphere to perform the phosphor firing step. After that, a vacuum firing step is performed. It was confirmed that Example 3 can exhibit the same effect as Example 1 and can exhibit the additional effect of more effectively removing any adsorbed substances such as water and hydrocarbons.
[0100] It was further demonstrated that the same effect can be obtained with dry air passed through a dehumidification filter instead of dry nitrogen.
