Disclosed are an organic-inorganic hybrid composition including a fluorene-based monomer, an inorganic particle, an initiator, and a solvent, and an image sensor made using the same. The organic-inorganic hybrid composition can have a high refractive index and excellent transmittance to minimize light loss, and the image sensor produced using the same may transport a greater amount of light to a photodiode. Accordingly, it is possible to accomplish a high resolution image sensor having improved sensitivity.
