PROBLEM TO BE SOLVED: To reduce slippage of a touch position resulted from difference in the visual line direction of a user. SOLUTION: A curved touch panel 15 is a capacitance type transparent touch panel having a curved face-like touch surface T. An LED 11 and a liquid crystal panel 13 display an image on the back surface of the curved face touch panel 15. A collimator lens 12 converts part of the light emitted from the LED 11 to parallel light. A lens array 14, which is composed of a plurality of two-dimensionally arranged reflective-index distribution type lenses, optically images an actual erecting image of the same magnification of the image displayed on the liquid crystal panel 13 to a space in the vicinity of the surface of the curved touch panel 15. The user touches the touch surface T of the curved face touch panel 15 while viewing the image imaged in the air. COPYRIGHT: (C)2008,JPO&INPIT
