Abstract
A planar discharge plasma display device which can be easily manufactured and has low optical loss includes a front and a rear plate, a plurality of anode signal lines and cathode signal lines arranged in an X-Y matrix on the rear plate and insulated so as not to be exposed to a discharge space. Anodes and cathodes protrude from the anode signal lines and cathode signal lines, respectively, near the intersections of the anode signal lines and the cathode signal lines. Barrier ribs are stacked on the anode signal lines and lodged between the anode signal lines and the front plate.
Claims4
A plasma display device of a matrix driving type comprising:
- a transparent front plate and a rear plate;
- a plurality of both anode signal lines and cathode signal lines arranged in the form of an X-Y matrix on said rear plate and insulated so that the plurality of both signal lines are protected from exposure to a discharge space;
- anodes and cathodes protruding from the corresponding signal lines near the intersections of said anode signal lines and said cathode signal lines and exposed to the discharge space, the protrusion of said anodes and said cathodes being in a plane parallel to a plane of said transparent front and rear plates;
- and
- barrier ribs provided between said anode signal lines and said front plate.
A plasma display device comprising:
- a transparent front plate and a rear plate;
- a plurality of insulated cathode signal lines arranged on said rear plate;
- a plurality of insulated anode signal lines arranged orthogonal to said cathode signal lines on said rear plate;
- barrier ribs disposed above and along said anode signal lines;
- anodes and cathodes protruding into a discharge space from said anode signal lines and said cathode signal lines such that said anodes are perpendicular to said cathodes and such that discharge between said anodes and cathodes occurs in a planar direction along said rear plate thus increasing optical efficiency.
