         9 . The ice making device of  claim 8 ,
 wherein the second nozzle end includes a first part extending from the inclined surface and a diameter of the first part being uniform or decreased toward one side, and   a second part in which the second liquid supply hole is formed and extended from first part.   
     
     
         10 . The ice making device of  claim 4 ,
 wherein a diameter of the first liquid supply hole is greater than a diameter of the second liquid supply hole.   
     
     
         11 . The ice making device of  claim 4 ,
 wherein a position of the sub_first liquid supplier is fixed during an ice separation process and a position of the sub_second liquid supplier is changed during the ice separation process.   
     
     
         12 . The ice making device of  claim 11 ,
 wherein the sub_first liquid supplier is disposed at a position spaced apart from the first tray, and   the sub_second liquid supplier is installed to the second tray.   
     
     
         13 . The ice making device of  claim 12 ,
 wherein the second tray includes a second one tray forming a portion of the second cell, and   a second another tray in contact with the second one tray during the ice making process and spaced apart from the second one tray during the ice separation process, and   wherein the sub_second liquid supplier is installed to move with the second another tray.   
     
     
         14 . The ice making device of  claim 13 ,
 wherein the second another tray includes an opening, and   the second liquid supply hole is aligned with the opening.   
     
     
         15 . The ice making device of  claim 14 ,
 wherein the sub_second liquid supplier further includes an outlet opening through which liquid supplied to the second cell is discharged.   
     
     
         16 . An ice making device comprising:
