Abstract: An image sensor includes a device isolation layer disposed in a substrate and defining pixel regions, and a grid pattern on a surface of the substrate. The grid pattern overlaps the device isolation layer between adjacent pixel regions in a direction perpendicular to the surface. The grid pattern has a width less than a width of the device isolation layer.

Abstract: An image sensor includes two or more phase-difference detection pixels disposed adjacent to each other, a plurality of general pixels spaced apart from the phase-difference detection pixels, first and second peripheral pixels, and first to third light shields. The first and second peripheral pixels are adjacent to the phase-difference detection pixels, and between the phase-difference detection pixels and the general pixels. The first light shield is disposed in one of the general pixels and has a first width. The second light shield extends into the first peripheral pixel from a first area between the phase-difference detection pixels and the first peripheral pixel, and has a second width different from the first width. The third light shield extends into the second peripheral pixel from a second area between the phase-difference detection pixels and the second peripheral pixel, and has a third width different from the first width.

Abstract: Optical sensors including a light-impeding pattern are provided. The optical sensors may include a plurality of photoelectric conversion regions, a plurality of lenses on the plurality of photoelectric conversion regions, and a light-impeding layer extending between the plurality of photoelectric conversion regions and the plurality of lenses. The light-impeding layer may include an opening between a first one of the plurality of photoelectric conversion regions and a first one of the plurality of lenses. The optical sensors may be configured to be assembled with a display panel such that the plurality of lenses are disposed between the light-impeding layer and the display panel.
