PURPOSE: An image sensor is provided to reduce light loss by preventing crosstalk due to incident light which passes through the color filter and is diffracted. CONSTITUTION: An image sensor comprises a first pixel, a second pixel and at least one light reflection pattern. The light reflection pattern inputs the incident light from the outside to the corresponding first or second pixel. A photo-electro converter(110R) is formed on the semiconductor substrate and generates electrons according to the light from the outside. A color filter(340R,340G) is formed on the upper side of the photo-electro converter. A light guide is positioned between the photo-electro converter and the color filter and induces the light from the outside through the color filter to the photo-electro converter in correspondence to the photo-electro converter.
