A document display apparatus of the invention displays a document containing a plurality of pages in such a manner that one page lies on top of another, allowing easy and intuitive identification of the first page of the document. When a page turning command is entered through an input device, a designator specifies a page which should become the first page of the document based on page layering sequence information stored in a page data table memory and a page location calculator calculates new display locations of the individual pages so that pages to be shown behind a current page (or the page in the topmost layer) are successively displaced from the current page by an amount determined by preset page offset values ( DELTA X, DELTA Y) except for the first page of which amount of displacement is increased by an additional page offset value (+ alpha ) in both the horizontal and vertical directions. An updating device updates information stored in the page data table memory in accordance with the newly calculated display locations and a display processor produces on-screen images of the individual pages based on the information stored in the page data table memory.
