Abstract
A plasma display panel includes a front panel wherein an electrode, a dielectric layer and a protective layer are formed on a substrate of the front panel; and a rear panel wherein an electrode, a dielectric layer and a barrier rib and a phosphor layer are formed on a substrate of the rear panel. The front panel and the rear panel are oppositely disposed to each other. The electrode of the front panel is composed of a transparent electrode and a bus electrode, and the bus electrode comprises a melted-solidified portion obtained by a melting and subsequent solidifying of electrically-conductive particles.
Claims4
A plasma display panel comprising:
- a front panel comprising a substrate, an electrode, a dielectric layer and a protective layer, wherein the electrode, the dielectric layer and the protective layer are formed on the substrate of the front panel;
- and,
- a rear panel comprising a substrate, an electrode, a dielectric layer and a barrier rib and a phosphor layer, wherein the electrode, the dielectric layer and the barrier rib and the phosphor layer are formed on a substrate of the rear panel;
- wherein the front panel and the rear panel are oppositely disposed to each other;
- wherein the electrode of the front panel is composed of a transparent electrode and a bus electrode;
- wherein the bus electrode comprises a melted-solidified portion obtained by a melting and subsequent solidifying of electrically-conductive particles;
- wherein the melted-solidified portion extends from the surface of the bus electrode to a limited depth thereof;
- and
- wherein the thickness of the melted-solidified portion is in the range of 0.2 t to 0.7 t where “t” denotes a thickness of the bus electrode.
A method for producing a plasma display panel comprising a front panel wherein an electrode, a dielectric layer and a protective layer are formed on a substrate of the front panel, the electrode of the front panel being composed of a transparent electrode and a bus electrode,
- a formation of the bus electrode comprising:
- (i) preparing a bus-electrode material which comprises electrically-conductive particles;
- (ii) supplying the bus-electrode material onto the transparent electrode formed on the substrate;
- (iii) heating the bus-electrode material to form the bus electrode therefrom;
- and
- (iv) heating the surface of the bus electrode as a local heat treatment to allow at least one of the electrically-conductive particles contained in the bus electrode to melt,
- wherein the electrically-conductive particles are contained only to the limited depth range of 0.2 t to 0.7 t from the surface of the bus electrode and are allowed to melt by the step (iv), where “t” denotes a thickness of the bus electrode.
