Solid-state imaging device, imaging apparatus, and electronic apparatus
The present technology relates to a solid-state imaging device, an imaging apparatus, and an electronic apparatus, which can suppress a color mixture without lowering the sensitivity. In pixels (red pixels (R pixels), green pixels (G pixels), and blue pixels (B pixels)) other than W pixels and adjacent to the W pixels, light shielding films thicker than those of the W pixels are formed at positions adjacent to the W pixels. Furthermore, the shorter the wavelength, the thicker the light shielding film in the RGB pixels other than the W pixels. The present technology is applicable to the solid-state imaging device.
