Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a display device simultaneously and suitably forming visible light and non-visible light. SOLUTION: The display device 5 includes: a display panel 9; a backlight 11 forming visible light VLO for illuminating the display panel 9 from its rear surface; a conversion part 51 converting a portion of the visible light VLO formed by the backlight 11 into non-visible light IL1 and emitting the non-visible light; and a photoelectric sensor 48 detecting the non-visible light IL1 which is emitted from the conversion part 51, transmitted through the display panel 9 from its rear surface side and reflected by an object to be detected in front of the display panel 9.
