DISPLAY DEVICE, DISPLAY METHOD, DISPLAY PROGRAM, RECORDING MEDIUM

A display device (1000) includes: a liquid crystal panel with built-in sensors (200) including a light sensor circuit (212); a detected information analyzing unit (130) detecting the location on the front surface of a panel (200) touched by an object based on the light intensity distribution detected by the light sensor circuit (212); an IR backlight (310) projecting light individually to the upper half and lower half of the panel surface from behind; a recognition area control circuit (110) obtaining a recognition area data specifying whether the location on the upper half of the panel surface or the lower half of the panel surface that is touched by an object is subjected to detection by a detected information analyzing unit (130); and a BL control unit (111) instructing the IR backlight (310) to project a smaller amount of light to a region specified in the recognition area data as not being subjected to location detection by the detected information analyzing unit (130).
