Definitions
- the present invention relates to a plasma display device and a method for producing a phosphor material constituting the phosphor layer.
- Plasma display devices (hereinafter referred to as “PDP devices”) have recently attracted attention as image display devices capable of realizing high definition and large screens.
- a plasma display panel (hereinafter referred to as "PDP") is a portion that displays an image of a PDP device, and is composed of a front plate and a back plate.
- the front plate includes a display electrode made of a striped transparent electrode and a metal bus electrode formed on a glass substrate, a dielectric layer covering the display electrode, and a protective layer.
- the back plate is a stripe-shaped address electrode formed on a glass substrate, a base dielectric layer covering the address electrode, a barrier rib formed on the base dielectric layer, and a phosphor formed between the barrier ribs. It consists of layers.
- the front plate and the back plate are sealed by a sealing material formed around the periphery thereof.
- a gap between the front plate and the back plate formed by sealing is filled with a discharge gas such as neon or xenon.
- a discharge gas is discharged by a voltage applied to an electrode group consisting of display electrodes and address electrodes, and a phosphor layer emits light by ultraviolet rays generated by the discharge. Display.
- the PDP performs full color display by additively mixing the so-called three primary colors (red, green, and blue).
- the PDP has a phosphor layer that emits red, green, and blue light.
- Each color phosphor layer is formed by laminating phosphor materials of each color.
- Zn SiO: Mn one of the typical green phosphor materials, has a negatively charged surface.
- Zn SiO Green brightness decreases due to degradation of Mn.
- the surface of Zn SiO: Mn is polarized by vapor deposition or baking.
- metal alkoxide is adhered to the surface of a phosphor material such as Zn SiO: Mn,
- PDP has been proposed that uses phosphor particles for PDP coated with a metal oxide coating by firing this (for example, see Patent Document 2).
- the metal alkoxide is a compound containing an organic substance
- the carbon-based compound remains on the phosphor surface if firing is not sufficiently performed.
- This carbon compound is decomposed by electric discharge.
- the carbon-based compounds decomposed over a long period of use are released into the discharge space, and the discharge becomes unstable.
- Patent Document 3 A technique has been devised (see, for example, Patent Document 3).
- Patent Document 1 Japanese Patent Laid-Open No. 11-86735
- Patent Document 2 JP-A-10-195428
- Patent Document 3 Japanese Patent Laid-Open No. 2001-236893
- a pair of substrates are arranged to face each other so that a discharge space is formed between the substrates, and a partition for partitioning the discharge space is arranged on at least one substrate, and the partition
- a PDP device having a panel body in which an electrode group is arranged on a substrate so that discharge is generated in a discharge space partitioned by a substrate and a phosphor layer that emits light by discharge is provided, and the phosphor layer is made of Zn SiO: Mn And (Y, Gd) BO: Green consisting of a mixture of Tb With phosphor layer, Zn SiO: Mn surface coated with magnesium oxide and XP
- the ratio of Mg element to Si element on the surface measured with S device is 0.7 or more and 6.0 or less.
