Abstract
An image sensor includes a sensing layer, a number of filter units, and a grid structure. The filter units are disposed on the sensing layer. The grid structure is disposed on the sensing layer and surrounding each of the filter units. The grid structure includes a first partition wall disposed on the sensing layer and located between two adjacent filter units, and a second partition wall disposed on the first partition wall located between the two adjacent filter units. The refractive index of the first partition wall is less than the refractive index of the second partition wall.
