Abstract
An apparatus includes a substrate on which a pixel with a color filter is formed. The pixel includes a first conversion portion and a second conversion portion in an in-plane direction of the substrate, the second conversion portion having a lower sensitivity to light than a sensitivity of the first conversion portion. In a depth direction of the substrate, the apparatus includes a first member between the first conversion portion and the color filter and a second member between the second conversion portion and the color filter in a depth direction of the substrate. The first member is adjacent to the second member in the in-plane direction of the substrate. A refractive index of the first member is higher than a refractive index of the second member.
