Front substrate of plasma display panel and fabricating method thereof

Abstract

Disclosed is a front substrate of a plasma display panel and fabricating method thereof, by which color temperature, color purity, and contrast of PDP are enhanced. The present invention includes an upper dielectric layer containing a colorant therein. And, the present invention includes the step of forming an upper dielectric layer having a colorant added thereto.

1 . A device of a plasma display panel having: 
 an upper glass substrate;    a transparent electrode and a bus electrode formed on the upper glass substrate;    an upper dielectric layer, having a colorant which comprises CuO and NiO, formed on the upper glass substrate including the transparent electrode and the bus electrode formed thereon;    a protection layer formed on the upper dielectric layer;    a lower glass substrate;    an address electrode formed on the lower glass substrate;    a lower dielectric layer formed on the lower glass substrate including the address electrode;    a barrier rib formed on the lower dielectric layer; and    a phosphor layer formed on the lower dielectric layer and the barrier rib.    
   
   
       2 . The device of  claim 1 , wherein the colorant is a substance for adjusting optical transmittance.  
   
   
       3 . The device of  claim 1 , wherein the colorant further comprises at least one of CoO, Nd2O3, Cr2O3, Pr2O3, and Fe2O3  
   
   
       4 . The device of  claim 1 , wherein the colorant is added below 5 wt %.
