Plasma display panel, manufacturing method and manufacturing apparatus of the same

Abstract

A method of manufacturing a plasma display panel, which comprises the steps of filling a barrier rib-forming paste containing glass frit in a barrier ribs-forming intaglio and concurrently forming a paste layer having a constant thickness on the intaglio, superimposing a substrate on the barrier ribs-forming intaglio filled with the barrier rib-forming paste containing glass frit to thereby transfer the barrier rib-forming paste onto the substrate, and heating the barrier rib-forming paste that has been transferred to the substrate, thereby burning out existing organic components and concurrently sintering the glass frit to thereby form the barrier ribs and dielectric layer. The plasma display panel manufactured by this method is featured in that the barrier ribs and the dielectric layer are formed using the same barrier rib-forming material containing a low melting point glass frit.

         1 . A plasma display panel comprising: 
 a back substrate;    electrodes each formed in a region partitioned;    barrier ribs arranged on said back substrate and partitioning said region; and    a dielectric layer covering said electrodes,    wherein said barrier ribs and said dielectric layer comprise the same barrier rib-forming material containing a low melting point glass frit, and a film thickness of said dielectric layer is in a range of 5 to 50 μm.    
     
     
         2 . The plasma display panel according to  claim 1 , wherein a film thickness of said dielectric layer is in the range of 5 to 20 μm.  
     
     
         3 . A plasma display panel comprising: 
 a back substrate;    electrodes each formed in a region partitioned; and    barrier ribs arranged on said back substrate and partitioning said region,    wherein said barrier ribs are formed of a recessed structure comprising a bottom structure contacting with said back substrate, and an upper structure projected from said bottom structure; and said electrodes are each disposed at the bottom of said recessed structure.    
     
     
         4 . The plasma display panel according to  claim 3 , wherein the visible light reflectivity of the regions other than the electrodes is 50% or more under the condition where a phosphor is not coated.  
     
     
         5 . The plasma display panel according to  claim 3 , wherein a recessed portion is formed at the bottom of the opening portion of the recessed structure, and the electrode is disposed at this recessed portion.  
     
     
         6 . The plasma display panel according to  claim 3 , wherein the width of the recessed portion is the same in size as the bottom of the opening portion of the recessed structure.  
     
     
         7 . The plasma display panel according to  claim 3 , wherein the thickness of the bottom of the recessed structure is larger than the width of the upper structure of recessed portion.  
     
     
         8 . A back plate of plasma addressed liquid crystal display panel comprising: 
 a back substrate;    a transparent dielectric layer formed on said back substrate;    transparent barrier ribs arranged on said transparent dielectric layer and comprising the same material as that of said transparent dielectric layer;    an anode formed on said transparent dielectric layer; and    a cathode formed on said transparent dielectric layer;    wherein a film thickness of said transparent dielectric layer is in a range of 3 to 15 μm.    
     
     
         9 . The back plate of plasma addressed liquid crystal display panel according to  claim 8 , wherein an angle between a sidewall of the transparent barrier rib and said back substrate is in a range of 85 to 95 degrees.  
     
     
         10 . The back plate of, plasma addressed liquid crystal display panel according to  claim 8 , wherein a surface roughness of the sidewall of the transparent barrier rib is 1 μm or less and is equivalent almost to an optical flat surface.  
     
     
         11 . A plasma display panel comprising: 
 a back substrate; and    barrier ribs arranged on said back substrate, wherein said barrier ribs are formed of a recessed structure comprising a bottom structure contacting with said back substrate, and an upper structure projected from said bottom structure; and visible light reflectivity of the back substrate is 50% or more under a condition where a phosphor is not coated.    
     
     
         12 . A plasma display panel comprising: 
 a back substrate; and    barrier ribs arranged on said back substrate, wherein said barrier ribs are formed of a recessed structure comprising a bottom structure contacting with said back substrate, and an upper structure projected from said bottom structure; and a thickness of the bottom structure of the recessed structure is larger than a width of the upper structure of the recessed structure.
