ABSTRACT OF THE DISCLOSURE A display apparatus automatically rounds corners of a rectangular area frame for display thereof, the rectangular area frame including that of a window or that of a graph and the like displayed within the window. The rounding is effected by automatically calculating and displaying the circular arcs (ellipstic arcs) of the corners based on the inputted corner coordinates of the rectangular area frame, or by not displaying one or several dots of each corner. In the case where multi-windows are displayed in an overlap manner or a plurality of rectangular area frames are displayed within a window, the corners are not displayed stiffly and emphasized unnecessarily, thus providing a visually soft and natural display image, improving the quality of displayed images, and providing an improved handy method for use by an operator. In a document editing apparatus, the corners of a rectangular frame of a window or of a rectangular area for display of graphs or the like in the window are visually recognized round, whereas the corners of a hard copy are formed with original angles.
