1 . A luminescent ink comprising a solvent and an organic compound represented by the following Formula (1), 
       
         
           
           
               
               
           
         
       
       wherein, in Formula (1), R 1  to R 22  each are respectively selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aryloxy group, a silyl group, and a cyano group; and the R 1  to R 22  may be identical to or different from one another. 
     
     
         2 . The luminescent ink according to  claim 1 , wherein R 1  to R 22  each are respectively selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted aryl group; and
 R 1  to R 22  may be identical to or different from one another.   
     
     
         3 . The luminescent ink according to  claim 2 , wherein R 1 , R 4 , R 9 , R 10 , R 17 , and R 18  each are respectively selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted aryl group, and R 1 , R 4 , R 9 , R 10 , R 17 , and R 18  may be identical to or different from one another; and R 2 , R 3 , R 12 , R 13 , R 14 , and R 15  each are respectively selected from a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, and a substituted or unsubstituted aryl group, and R 2 , R 3 , R 12 , R 13 , R 14 , and R 15  may be identical to or different from one another. 
     
     
         4 . The luminescent ink according to  claim 1 , further comprising a binder resin. 
     
     
         5 . The luminescent ink according to  claim 4 , wherein the binder resin is selected from the group consisting of a polyvinyl carbazole resin, a polycarbonate resin, a polyester resin, an ABS resin, an acrylic resin, a polyimide resin, a phenol resin, an epoxy resin, a silicone resin, and a urea resin. 
     
     
         6 . The luminescent ink according to  claim 4 , wherein the binder resin comprises two or more kinds of materials. 
     
     
         7 . The luminescent ink according to  claim 1 , further comprising at least one of plasticizer, an antioxidant, and a UV absorber.
