A display apparatus of the type that is fitted to the user's head or face, and having a higher resolution in a first region of the display than that of the remaining area of the display, without increasing the size of the display. As an example, an image of the characters "ABC", for example, are generated or received. However, it might be desired that the center character "B", for example, be displayed at a higher resolution than that of the characters "A C". To accomplish this, the original image "ABC" is divided into an image of "A C" and an image of "B". Then, the image of "B" is electrically distorted and formed on a screen such that the image of "B" is larger in size than the image of "A C". An ocular optical system including an optical element effects a second distortion of the image to correct the electrically created distortion. This ocular optical system enlarges the image such that the image of "A C", which has been displayed relatively small, is enlarged, and projects the image of "B", which has been displayed relatively large, through a lens having a correspondingly lower magnification. Then, the image of "B" is superimposed on the image of "A C" so that the image of "A C" and "B" are displayed at the same size, but with "B" being represented by more pixels or pixels which are finer than those representing "A C".
