US 2009/0153017 A1 · PLASMA DISPLAY PANEL AND METHOD OF MANUFACTURING THE SAME

Abstract

A plasma display panel including: a first substrate; a second substrate facing the first substrate; an electrode sheet including: a barrier rib structure between the first and second substrates defining a plurality of discharge cells in which discharge occurs; a plurality of first discharge electrodes which are separated from each other in the barrier rib structure and extend between the first substrate and the second substrate with portions that surround the discharge cells; and a plurality of second discharge electrodes which are separated from each other and the first discharge electrodes in the barrier rib structure and extend between the first substrate and the second substrate with portions that surround the discharge cells; a phosphor layer on at least one of the first and second substrates; a discharge gas filled in the discharge cells; and a plurality of first aligning marks in the electrode sheet.

A method of manufacturing a plasma display panel, the method comprising:

preparing an electrode sheet comprising:
a plurality of first discharge electrodes which are separated from each other in a barrier rib structure and have portions that surround discharge cells;
and a plurality of second discharge electrodes which are separated from each other and the first discharge electrodes in the barrier rib structure and have portions that the surround discharge cells;
forming first aligning marks in one of a top surface and a bottom surface of the electrode sheet;
forming sacrifice layers on both the top and bottom surfaces of the electrode sheet;
aligning exposure masks to be aligned to the first aligning marks on the top and bottom surfaces of the electrode sheet;
patterning the sacrifice layers on the top and bottom surfaces of the electrode sheet by exposing the electrode sheet;
forming discharge cell regions between the discharge electrodes by etching the top and bottom surfaces of the electrode sheet exposed through the patterned sacrifice layers;
removing the sacrifice layers;
and
frit sealing first and second substrates facing each other by interposing the electrode sheet between the first and second substrates.
