The information processing device according to  claim 1 , wherein the display control unit is configured to, in response to a user operation, perform display of separating a predetermined number of list items from the first list, and display a new sub-list including the predetermined number of the separated list items. 
     
     
         3 . The information processing device according to  claim 1 , further comprising a detection unit configured to detect a user operation,
 wherein the display control unit is configured to, when the detection unit detects an operation of the user to widen a distance between a plurality of operation positions, perform display of coupling the second list to the first list.   
     
     
         4 . The information processing device according to  claim 1 , further comprising a detection unit configured to detect a user operation,
 wherein the display control unit is configured to, when the detection unit detects an operation of the user to narrow a distance between a plurality of operation positions, perform display of separating the list items from the first list to create a new sub-list.   
     
     
         5 . The information processing device according to  claim 1 , wherein the display control unit is configured to, when the list items of the second list are moved into the first list through a drag operation of the user, perform display of coupling the second list to the first list. 
     
     
         6 . The information processing device according to  claim 1 , wherein the display control unit is configured to, in accordance with a movement amount or a movement speed of the operation positions, changes the number of sub-lists to be coupled or the number of sub-lists to be newly created. 
     
     
         7 . The information processing device according to  claim 1 , wherein as the second list is coupled to the first list and the number of the list items of the first list increases, information that is displayed by the first list becomes more detailed. 
     
     
         8 . The information processing device according to  claim 1 , wherein the list items of the second list are displayed in size smaller than the list items of the first list. 
     
     
         9 . The information processing device according to  claim 8 , wherein the display control unit is configured to perform display of coupling the list item of the second list to the first list by moving the list item while enlarging the list item. 
     
     
         10 . The information processing device according to  claim 8 , wherein the display control unit is configured to perform display of coupling the list item of the second list to the first list by enlarging the list item after the list item has moved to the first list. 
     
     
         11 . The information processing device according to  claim 1 , wherein the display control unit is configured to perform display of coupling the list item of the second list to the first list by moving the list item without changing a size of the list item. 
     
     
         12 . The information processing device according to  claim 4 , wherein the display control unit is configured to, in response to an operation of the user to narrow the distance between the plurality of operation positions, perform display of shrinking a predetermined number of list items of the first list so that the shrunk list items move away from and separated from the first list, and further display a new sub-list by arranging the list items separated from the first list. 
     
     
         13 . An information processing method comprising:
 displaying a plurality of lists including a first list and a second list each having list items; and   performing display of coupling to the first list a list item of the second list that is a sub-list of the first list.   
     
     
         14 . A program causing a computer to execute processes of:
 displaying a plurality of lists including a first list and a second list each having list items; and   performing display of coupling to the first list a list item of the second list that is a sub-list of the first list.   
     
     
         15 . The program according to  claim 14 , causing a computer to further execute processes of performing display of, in response to a user operation, separating a predetermined number of list items from the first list, and display of a new sub-list including the predetermined number of the separated list items. 
     
     
         16 . The program according to  claim 14 , causing a computer to further execute processes of:
 detecting a user operation; and   performing display of, when the detecting process detects an operation of the user to widen a distance between a plurality of operation positions, coupling the second list to the first list.   
     
     
         17 . The program according to  claim 14 , causing a computer to further execute processes of:
 detecting a user operation; and   performing display of, when the detecting process detects an operation of the user to narrow a distance between a plurality of operation positions, separating the list items from the first list to create a new sub-list.   
     
     
         18 . The program according to  claim 14 , causing a computer to further execute, when the list items of the second list are moved into the first list through a drag operation of the user, performing display of coupling the second list to the first list. 
     
     
         19 . The program according to  claim 14 , causing a computer to further execute, in accordance with a movement amount or a movement speed of the operation positions, a process of changing the number of sub-lists to be coupled or the number of sub-lists to be newly created. 
     
     
         20 . The program according to  claim 14 , causing a computer to further execute a process such that, as the second list is coupled to the first list and the number of the list items of the first list increases, information that is displayed by the first list become's more detailed.
