Abstract

A protective plate for a plasma display including a conductive substrate for protecting the plasma display. The conductive substrate includes a substrate having a glass plate and a conductive film formed on a resinous film bonded to the glass plate substrate. The plasma display also includes an electrode in electrical contact with the conductive substrate.

Claims

1. A protective plate for a plasma display, comprising:

a conductive substrate for protecting the plasma display, the conductive substrate including a substrate comprising a glass plate, and a conductive film formed on a resinous film bonded to the glass plate substrate; and

an electrode in electrical contact with the conductive substrate.

2. The protective plate for a plasma display according to claim 1, wherein the glass plate is a glass made of strengthened glass.

3. The protective plate for a plasma display according to claim 1, wherein the resinous film is polyethyleneterephthalate.

4. The protective plate of claim 1, wherein the electrode comprises a conductive material formed around a periphery of a main surface of the glass plate.

5. The protective plate of claim 4, wherein the conductive film is formed on the resinous film bonded to a middle portion of said main surface of the glass plate.

6. The protective plate of claim 5, wherein the conductive film covers at least a portion of the conductive material such that the conductive material is interposed between the conductive film and the glass plate.

7. The protective plate of claim 6 further comprising a colored ceramic layer formed around said periphery of a main surface of the glass plate and interposed between said glass plate and the conductive material.
