Zusammenfassung:	A light detection device includes a semiconductor substrate, a signal detection light receiving portion, and an infrared light receiving portion. First and second color filters cover the signal detection light receiving portion and the infrared light receiving portion, respectively. The first color filter passes therethrough visible light in a first wavelength range as well as infrared light. The second color filter passes therethrough visible light in a second wavelength range as well as infrared light. A third color filter covers the infrared light receiving portion. The third color filter passes therethrough visible light in a third wavelength range different from the second wavelength range as well as infrared light. An infrared cut filter covers the signal detection light receiving portion and has an opening in a region opposite to the infrared light receiving portion.
