A method of searching for a page in a three dimensional manner in a portable device includes overlappingly displaying a plurality of pages in three dimensions; detecting a distance between the portable device and a user input means; sequentially moving and displaying the plurality of pages according to the detected distance; and when a movement of the user input means for selecting a page is detected, displaying the selected page. As a user brings a user input means close to a front surface of the portable device, the pages having the laminated structure are sequentially moved and displayed one by one, starting from a page displayed on the front.
