         8 . The backlight assembly of  claim 1 , wherein the light source supporter includes a metal plate. 
     
     
         9 . The backlight assembly of  claim 8 , wherein the light source supporter includes aluminum. 
     
     
         10 . The backlight assembly of  claim 1 , wherein the second region of the light source supporter extends from the light source and provides a heat dissipation path for the backlight assembly. 
     
     
         11 . The backlight assembly of  claim 1 , wherein the light source supporter contacts the first receiving unit and dissipates heat. 
     
     
         12 . The backlight assembly of  claim 4 , wherein the bent portion of the second region is disposed along the side wall of the first receiving unit and contacts the side wall. 
     
     
         13 . The backlight assembly of  claim 1 , wherein
 a hole is formed in the bottom surface of the first receiving unit, and the light source supporter further comprises a protrusion disposed in the hole.   
     
     
         14 . A liquid crystal display, comprising:
 a liquid crystal panel which displays an image;   a backlight assembly comprising:
 a light source disposed adjacent to an edge portion of the liquid crystal panel; 
 a light guide plate disposed adjacent to the light source and which emits light to the liquid crystal panel; 
 an optical sheet disposed between the light guide plate and the liquid crystal panel; 
 a first receiving unit including a bottom surface and a side wall and which accommodates the light source, the light guide plate and the optical sheet; and 
 a light source supporter which supports the light source and the light guide plate, the light source and the light guide disposed on a first region of the light source supporter; and 
   a second receiving unit covering at least a portion of the edge portion of   
       the liquid crystal panel and the side wall of the first receiving unit. 
     
     
         15 . The liquid crystal display of  claim 14 , wherein the light source supporter comprises a second region extending from the first region of the light source supporter. 
     
     
         16 . The liquid crystal display of  claim 15 , wherein a gap is formed on the second region of the light source supporter and between an end portion of the second region and the light source.
