Abstract
A vacuum display device for enabling the manufacture of high quality plasma display device with high throughput. A front panel 6 constituting a plasma display device is carried into a film deposition chamber 22; and a MgO thin film is deposited in a vacuum atmosphere. The front panel 6 is then carried into an alignment chamber 11 without being exposed to the atmosphere and aligned with a rear panel 7 that has been subjected to degassing in a vacuum atmosphere. There is no absorption of gas, such as moisture; and the quality of the thin film is not degraded. After alignment, aging processing is carried out without exposure to the atmosphere, followed by gas encapsulation and hermetic sealing, which further increases throughput.
