The subject of the present disclosure is to enhance spectral characteristics.
The present disclosure relates to an optical sensor and an electronic apparatus. The optical sensor includes: multiple optical receivers, multiple color filters covering light receiving surfaces of the multiple optical receivers, and a multi-layer filter layered on the multiple color filters. The multiple color filters include a red color filter, a green color filter and a blue color filter. The multi-layer filter includes a first transmission wavelength region allowing transmission of a portion of the transmission wavelength regions of the green color filter and the blue color filter, and a second transmission wavelength region allowing transmission of a portion of the transmission wavelength region of the red color filter.
