Abstract
An image sensor may include an antireflection layer formed over a substrate, grid patterns and a guide pattern that are disposed over the antireflection layer, a color filter between the grid patterns, a phase difference detection filter structured to include a portion between one of the grid patterns and the guide pattern, and a lining layer formed to include a portion between one of the grid patterns and the phase difference detection filter. The lining layer has a refractive index lower than that of the phase difference detection filter.
