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: An image sensor that provides a uniform sensitivity for pixels having color filters of the same color to increase the image quality is provided. The image sensor includes a substrate, a first grid pattern disposed on the substrate and including a first side wall and a second side wall opposite to the first side wall, a first pixel including a first photoelectric conversion element and a first color filter, and a second pixel including a second photoelectric conversion element and a second color filter. The first color filter contacts the first side wall and the second color filter contacts the second side wall. The first color filter and the second color filter are color filters of same color, and a first thickness of the first color filter is greater than a second thickness of the second color filter.

Abstract: An image sensor in which a shading phenomenon is decreased and the quality is increased is provided. The image sensor includes a light-receiving region including a plurality of unit pixels. The image sensor further includes a first region with unit pixels adjacent to a center of the light-receiving region, and a second region with the unit pixels spaced apart from the center of the light-receiving region. In both regions, a plurality of color filters corresponding to the plurality of unit pixels is disposed on a first face of the substrate, as well as a grid pattern interposed between the plurality of color filters defining boundaries between the unit pixels. A width of the grid pattern in the second region is greater than a width of the grid pattern in the first region, thereby adjusting light receiving areas near the edge of the image sensor to correct for a shading phenomenon.

Abstract: An electronic device may include a photoelectric element, a shielding layer on the photoelectric element, and a color filter structure on the shielding layer. The shielding layer may define a first opening over the photoelectric element. The color filter structure may define a second opening over the photoelectric element and the first opening. The color filter structure may appear dark from a view facing the color filter structure.
