Image sensing device

Abstract

An image sensing device includes a plurality of color filter blocks, each of which includes a plurality of color filters arranged adjacent to each other in a first direction and a second direction perpendicular to the first direction and having the same color, first grid structures including a first air layer and disposed between the color filter blocks adjacent to each other in the first direction; second grid structures including a second air layer and disposed between the color filter blocks adjacent to each other in the second direction, and a third grid structure including a third air layer and disposed between the color filters within each of the color filter blocks. The first to third air layers are structurally separate from each other.
