A touch-screen display which is able to prevent a displacement of a display position and a touch position. The touch-screen display includes a pointing pen for pointing to a position on the touch panel, and which may represent a position of an operator's eye. Moreover, the touch-screen display includes a correction unit for correcting the pointing position pointed to by the pointing pen. Therefore, the displacement of display position and a touch position caused by an angle of an operator's line of sight can be compensated for.
