Abstract: An image sensor includes a sensor substrate including a plurality of light sensing cells configured to sense light, and a color filter array provided on the sensor substrate. The color filter includes a plurality of filters provided to respectively face the plurality of light sensing cells to filter light of different wavelengths and a fence structure configured to separate the plurality of filters from each other. A width of the fence structure may have a plurality of different values according to types of two filters provided adjacent to each other with the width interposed therebetween. Crosstalk between adjacent cells may be reduced by the image sensor.
