A method for producing a plasma display comprises the step of continuously applying a phosphor paste containing a phosphor powder and an organic compound onto a substrate with a plurality of barrier ribs, from a paste applicator with a plurality of outlet holes. A method for producing a plasma display comprises the steps of coating a substrate with a plurality of baffler ribs, with three phosphor pastes respectively containing a phosphor powder emitting light of red, green or blue, as stripes in the spaces between the respectively adjacent baffler ribs on the substrate, from a paste applicator with outlet holes, and heating to form a phosphor layer. An apparatus for producing a plasma display comprises a table for fixing a substrate with a plurality of baffler ribs, a paste applicator with a plurality of outlet holes to face the baffler ribs of the substrate, a supply means for supplying a phosphor paste to the paste applicator, and a moving means for three-dimensionally moving the table and the paste applicator relatively each other.

Method and apparatus for producing a plasma display

A board for a plasma color display, on which striped barrier ribs for partitioning address electrodes and discharge spaces are formed, and on which phosphor layer stripes emitting light of red, green and blue are formed in the grooves between the respectively adjacent barrier ribs, characterized in that the following relation is satisfiedPb&#x3e;Prwhere Pr is the distance between respectively adjacent barrier ribs for forming a red light emitting phosphor layer, and Pb is the distance between respectively adjacent barrier ribs for forming a blue light emitting phosphor layer, and that the height differences of the barrier ribs within the board face are within &#xb1;0.5&#x2dc;&#xb1;6 &#x3bc;m in reference to the average height of the barrier ribs, or characterized in that phosphor layer stripes respectively emitting light of the same color are formed in respectively adjacent two or more grooves. The present invention can also provide a plasma display which allows a well-balanced brighter color image to be displayed and allows a beautiful white image to be displayed in the case of full face light emission. The present invention can also provide a process for producing the same.
