Liquid crystal display

Abstract

A liquid crystal display including a first substrate; a second substrate facing the first substrate; a first field generating electrode disposed on the first substrate; a second field generating electrode disposed on the second substrate; and a liquid crystal layer disposed between the first substrate and the second substrate, the liquid crystal layer including a liquid crystal and an alignment assistant, wherein the alignment assistant includes a mesogen and two or more photo-polymerizable groups.

What is claimed is: 
     
         1 . A liquid crystal display comprising:
 a first substrate;   a second substrate facing the first substrate;   a first field generating electrode disposed on the first substrate;   a second field generating electrode disposed on the second substrate; and   a liquid crystal layer disposed between the first substrate and the second substrate, the liquid crystal layer including a liquid crystal, a first alignment assistant and a second alignment assistant,   wherein the first alignment assistant includes a non-mesogen and three or more photo-polymerizable groups, and   a second alignment assistant includes a mesogen and two or more photo-polymerizable groups.   
     
     
         2 . The liquid crystal display of  claim 1 , wherein
 the photo-polymerizable group includes at least one group selected from the group consisting of an acrylate group, a methacrylate group, and a combination comprising at least one of the foregoing photo-polymerizable groups.   
     
     
         3 . The liquid crystal display of  claim 2 , wherein
 the first alignment assistant includes at least one compound selected from the group of compounds represented by Chemical Formulas 5 to 10:   
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
       
     
     
         4 . The liquid crystal display of  claim 2 , wherein
 the second alignment assistant includes at least one compound selected from the group of compounds represented by Chemical Formulas 1 to 4 and Chemical Formulas 11 to 21:   
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         
           
           
               
               
           
         
       
     
     
         5 . The liquid crystal display of  claim 1 , wherein
 at least one of the first alignment assistant and the second alignment assistant is contained in an amount between about 0.1 weight percent to about 10 weight percent with respect to the content of the liquid crystal.   
     
     
         6 . The liquid crystal display of  claim 5 , wherein
 the second alignment assistant is contained in an amount between about 40 weight percent to about 90 weight percent with respect to the total content of the first and the second alignment assistants.   
     
     
         7 . The liquid crystal display of  claim 1 , wherein
 at least one of the first and the second field generating electrodes comprises a branch shape.   
     
     
         8 . The liquid crystal display of  claim 1 , wherein:
 at least one of the first and the second alignment assistants comprises a non-polymerized alignment assistant; and   the non-polymerized alignment assistant is contained in an amount less than or equal to about 5 weight percent with respect to a total content of the first and the second alignment assistant.
