wherein the control unit controls to display a first user interface element from among the plurality of user interface elements as an individual user interface element when the frequency of use of a first service item corresponding to the first user interface element is greater than a pre-set frequency of use, and display a second user interface element from among the plurality of user interface elements as a sub-user interface element of a representative user interface element when the frequency of use of a second service item corresponding to the second user interface element is less than the pre-set frequency of use,

wherein in response to a command of selecting the individual user interface element, the control unit controls to display the first service item corresponding to the selected individual user interface element, and in response to a command of selecting the representative user interface element, the control unit controls to display the sub-user interface element which belongs to the selected representative user interface element.

9. The display apparatus according to claim 8 , wherein the frequency of use of the plurality of service items is one of a total frequency of use of the plurality of service items and a recent frequency of use of the plurality of service items.

10. The display apparatus according to claim 9 , wherein the representative user interface element is classified according to categories or users.

11. The display apparatus according to claim 9 , wherein the plurality of service items comprise at least one of a service item for setting a function of the display apparatus and a service menu item for obtaining information through the Internet.

12. The display apparatus according to claim 9 , wherein the UI generation unit generates the plurality of service items in widget form.

13. The display apparatus according to claim 8 , wherein the second user interface element sequentially shows information regarding a respective menu item as a slideshow.

14. The display apparatus according to claim 8 , wherein the individual user interface element comprises a first icon and the representative user interface element comprises a second icon.

15. A method for providing a plurality of service items, the method comprising:

receiving a user input regarding at least one service item from among a plurality of a service items;

analyzing a frequency of use of the plurality of service items based on the user input; and

determining where a plurality of user interface elements corresponding to the plurality of service items are to be displayed based on the frequency of use of the plurality of service items,

wherein the determining where the plurality of service items are to be displayed comprises displaying a first user interface element from among the plurality of user interface elements as an individual user interface element when the frequency of use of a first service item corresponding to the first user interface element is greater than a pre-set frequency of use, and displaying a second user interface element from among the plurality of user interface elements as a sub-user interface element of a representative user interface element when the frequency of use of a second service item corresponding to the second user interface element is less than the pre-set frequency of use, and

wherein in response to a command of selecting the individual user interface element, the first service item corresponding to the selected individual user interface element is displayed, and in response to a command of selecting the representative user interface element, the sub-user interface element which belongs to the selected representative user interface element is displayed.

16. The method of claim 15 , wherein the plurality of service items are generated in widget form.
