    • An image sensing device includes photoelectric conversion elements structured to convert light into electrical signals, and a color filter layer structured to filter incident light towards the photoelectric conversion elements depending on a wavelength range of the incident light corresponding to colors of the incident light to allow the filtered light to be detected by the photoelectric conversion elements corresponding to the colors of the incident light. The color filter layer includes a plurality of first color filters as part of the different filters and structured to allow light at a wavelength range corresponding to a first color and arranged adjacent to each other. A distance between at least one of the first color filters and a corresponding photoelectric conversion element formed below the at least one of the first color filters is different from a distance between the remaining first color filters and corresponding photoelectric conversion elements, respectively.

    • An image sensing device includes a pixel array including image sensing pixels, phase detection pixel pairs disposed between the image sensing pixels, photoelectric conversion regions corresponding to the image sensing pixels and the phase detection pixels, device isolation structures isolating the photoelectric conversion regions, color filters corresponding to the image sensing pixels and the phase detection pixel pairs, a first grid structure disposed between a color filter of a first image sensing pixel and a color filter of an adjacent first phase detection pixel pair and shifted by a first distance from a first device isolation structure disposed between the first image sensing pixel and the first phase detection pixel pair, and a second grid structure disposed in color filters of the first phase detection pixel pair and shifted by a second distance from a second device isolation structure disposed between the first phase detection pixel pairs.
