Original Abstract Submitted
Provided is a light detection device capable of reducing an inter-same-color sensitivity difference Provided are: a color filter layer including a plurality of color filters each transmitting light of a predetermined wavelength component contained in light condensed by a microlens; and a low-refractive-index layer that is at least partially arranged between the color filters and contains air or a low-refractive-index material having a lower refractive index than a material of an adjacent layer. Then, the low-refractive-index layer has a first width on the microlens side and a second width, narrower than the first width, on a side closer to a substrate than a portion having the first width.
