Abstract
Image sensors include a color photo-sensing photoelectric conversion device, a first color filter and a second color filter disposed under the color photo-sensing photoelectric conversion device, a first photodiode and a second photodiode disposed under the first color filter and the second color filter, respectively, a first light guide member disposed between the first color filter and the first photodiode, and a second light guide member disposed between the second color filter and the second photodiode.
