Abstract
There is provided a PDP including a front substrate and a rear substrate. The front substrate and the rear substrate are disposed via discharge spaces. The discharge spaces are filled with a discharge gas. In the discharge spaces or in a space permeable to the discharge spaces, a copper-ion-exchanged zeolite adsorbent is disposed which is in an activated state.
Claims31
A plasma display panel comprising:
- a front substrate including;
- a plurality of display electrode pairs formed on a surface of the front substrate,
- a first dielectric layer formed to cover each of the display electrode pairs, and
- a protective layer formed on the first dielectric layer, and
- a rear substrate including;
- a plurality of data electrodes formed on a surface of the rear substrate,
- a second dielectric layer formed to cover each of the data electrodes,
- a plurality of barrier ribs formed on the second dielectric layer, and
- a phosphor layer formed one of directly and indirectly on side surfaces of the barrier ribs and on a surface of the second dielectric layer,
- the front substrate and the rear substrate being disposed via a discharge space such that a face on which the protective layer is formed confronts a face on which the barrier ribs formed thereon, the discharge space being filled with a discharge gas,
- wherein
- a copper-ion-exchanged zeolite adsorbent is disposed in one of the discharge space and a space permeable to the discharge space, and
- the adsorbent is in a activated state.

A method of manufacturing a plasma display panel, the method comprising:
- forming a front substrate,
- forming a rear substrate,
- assembling the front substrate and the rear substrate to overlap each other via a sealing material,
- sealing the assembled front substrate and the assembled rear substrate,
- evacuating a space between the assembled front substrate and the assembled rear substrate, and
- introducing a discharge gas into a discharge space between the front substrate and the rear substrate,
- wherein
- at least one of the step of forming the front substrate and the step of forming the rear substrate includes a step of disposing a copper-ion-exchanged zeolite adsorbent in one of the discharge space and a space communicatively connected with the discharge space.
