Abstract
Provided is a light detection apparatus with high functionality. The light detection apparatus includes an effective region provided with a photoelectric converter that detects irradiation light and performs photoelectric conversion, and a peripheral region provided adjacent to the effective region. The photoelectric converter has a stacked structure including a first photoelectric conversion unit, a second photoelectric conversion unit, and a first optical filter. The first photoelectric conversion unit detects light in a first wavelength range of the irradiation light and performs photoelectric conversion. The second photoelectric conversion unit is provided so as to overlap with the first photoelectric conversion unit, detects light in a second wavelength range of the irradiation light, and performs photoelectric conversion. The first optical filter is provided between the first photoelectric conversion unit and the second photoelectric conversion unit and through which the light in the second wavelength range transmits more easily than the light in the first wavelength range. The peripheral region is provided with a second optical filter through which the light in the second wavelength range transmits more easily than the light in the first wavelength range.
