More Information
Summary:A light sensor according to an aspect of the present disclosure includes a photoelectric conversion layer and a long-pass filter that is disposed above the photoelectric conversion layer. The photoelectric conversion layer has a spectral sensitivity characteristic having a first peak at a first wavelength that is longer than a cut-on wavelength of the long-pass filter, and a spectral sensitivity of the photoelectric conversion layer at the cut-on wavelength is greater than or equal to 0% and less than or equal to 50% of a spectral sensitivity of the photoelectric conversion layer at the first wavelength.
