    • A display device of the present invention includes a display panel (101) including a photodiode (17), which generates a current having a magnitude corresponding to an intensity of light incident on the photoelectric conversion element; and, a backlight (108) for irradiating light from behind the photodiode (17) to beyond a front surface of the display panel (101), wherein: the photodiode (17) includes an activating layer made of hydrogenated a-Si; the light source (108) has a peak wavelength within a range from 780 nm or more to 830 nm or less; and the display device further includes a light blocking member (15) for blocking light having a wavelength less than 780 nm, the light blocking member (15) being provided between a front surface of the display panel (101) and the photodiode (17) and over the photodiode (17). With this, the present invention can perform a stable sensing operation under various environments because the display device is configured to reduce the outside-light-caused noise to the optical sensor and the display device is therefore less susceptible to environment surrounding the display device (outside light intensity etc.).A display device of the present invention includes a display panel (101) including a photodiode (17), which generates a current having a magnitude corresponding to an intensity of light incident on the photoelectric conversion element; and, a backlight (108) for irradiating light from behind the photodiode (17) to beyond a front surface of the display panel (101), wherein: the photodiode (17) includes an activating layer made of hydrogenated a-Si; the light source (108) has a peak wavelength within a range from 780 nm or more to 830 nm or less; and the display device further includes a light blocking member (15) for blocking light having a wavelength less than 780 nm, the light blocking member (15) being provided between a front surface of the display panel (101) and the photodiode (17) and over the photodiode (17).
