Abstract
In a panel unit 10, a discharge gas is filled into a discharge space 13. A protective layer 114 is provided in a partial region (a front panel 11 side) facing the inner space 13, and a phosphor layer 124 is provided in a counter region (a back panel 12 side) which holds the discharge space 13. The discharge gas is set at a total pressure of not less than 1.50×104 [Pa] and not more than 6.66×104 [Pa], and comprises an Xe gas as a first gas component and an Ar gas as a second gas component and is free from an Ne gas, provided that the Ne gas may be contained in the discharge gas at a partial pressure ratio of not more than 0.5[%] based on the total pressure.
Claims24
A plasma display panel comprising a hermetically sealed container containing discharge gas in an inner space therein, the hermetically sealed container including a protective layer and a phosphor layer opposing each other across the space, wherein the discharge gas contains:
- a first gas component composed of a rare gas element which emits light to excite a phosphor in the phosphor layer during a plasma discharge;
- a second gas component composed of an argon gas;
- and
- a neon gas at a partial pressure ratio in a range of 0% to 0.5%, inclusive, to a total pressure of the discharge gas, and wherein
- the second gas component is contained at a partial pressure ratio in a range of 1% to 25%, inclusive, to the total pressure of the discharge gas, and
- the total pressure of the discharge gas in the space is from 1.50×104 Pa to 6.66×104 Pa, inclusive.
A plasma display panel apparatus comprising i) a panel unit having a hermetically sealed container containing discharge gas in an inner space therein, the hermetically sealed container including a protective layer and a phosphor layer opposing each other across the inner space and ii) a drive unit operable to apply, in accordance with an inputted image signal, a voltage pulse to each electrode of an electrode pair of the panel unit, wherein the discharge gas contains:
- a first gas component composed of a rare gas element which emits light to excite a phosphor in the phosphor layer during a plasma discharge;
- a second gas component composed of an argon gas;
- and
- a neon gas at a partial pressure ratio in a range of 0% to 0.5%, inclusive, to a total pressure of the discharge gas, and
- the second gas component is contained at a partial pressure ratio in a range of 1% to 25%, inclusive, to the total pressure of the discharge gas, and
- the total pressure of the discharge gas in the space is from 1.50×104 Pa to 6.66×104 Pa, inclusive.
