Benefits of technology
[0014]It is therefore an object of the present invention to provide a plasma display and a manufacturing method thereof, in which a sintering process to form barrier ribs is not needed, and a screen-printing process may be applied to form electrodes and dielectric layers.
[0016]It is still another object to provide a plasma display that is easier and less expensive to manufacture and yet maintain or exceed the quality of the plasma display.
[0017]It is yet another object to provide a method of manufacturing a plasma display that can avoid the need to provide materials for electrodes and dielectric layers to the innermost portions between the main barrier ribs.
Problems solved by technology
The dielectric layer is made difficult to remove by sand blasting as a result of the sintering the dielectric layer as described above.
However, with the application of heat to glass (original substrate glass in this case) during sintering, the glass undergoes deformation (e.g., contracts).
However, since a height of the barrier ribs is 150 μm (micrometers) or more, it becomes an involved process to provide the materials to the bottom of and between the barrier ribs, thereby making application of the screen-printing process difficult.

Embodiment Construction
[0055]Turning now to the drawings, a prior art plasma display, with reference to FIG. 40, includes two glass substrates 1 and 2 provided opposing one another (hereinafter referred to as the front substrate 1 and the rear substrate 2). A plurality of electrodes 4 are formed over an inside surface of the front substrate 1, and a dielectric layer 3, which includes a protection layer made of a compound such as MgO, is formed covering the electrodes 4. Further, a plurality of electrodes 6 is formed on an inside surface of the rear substrate 2. The electrodes 6 are provided perpendicular to the electrodes 4 formed on the front substrate 1. In order to form discharge cells 7, which are spaces where gas discharge is performed, a plurality of barrier ribs 8 are formed on the rear substrate 2. That is, the barrier ribs 8 are formed to both sides of each of the electrodes 6 and parallel to the same. Dielectric layers 5 with a high reflexibility are formed covering the electrodes 6 and on surfa...

A plasma display includes first and second substrates provided opposing one another. A plurality of first electrodes is formed on a surface of the first substrate facing the second substrate. A first dielectric layer is formed covering the first electrodes. A plurality of main barrier ribs is formed on a surface of the second substrate facing the first substrate, the main barrier ribs defining a plurality of discharge cells. A plurality of electrode barrier ribs is formed on the second substrate between the main barrier ribs. Phosphor layers are formed within the discharge cells, and discharge gas included in the discharge cells, where the main barrier ribs are formed integrally to the second substrate, and a second electrode and a second dielectric layer are formed, in this order, on a distal end of each of the electrode barrier ribs. A method of manufacturing the plasma display includes the processes of integrally forming a plurality of main barrier ribs on a plasma display substrate, the main barrier ribs defining a plurality of discharge cells, forming electrode barrier ribs between the main barrier ribs, forming an electrode on a distal end of each of the electrode barrier ribs, and forming a dielectric layer on each of the electrodes.
