Abstract: An image sensor is provided. An image sensor includes: a substrate including an active pixel sensor region, an optical black sensor region, and a boundary region provided between the active pixel sensor region and the optical black sensor region; a photoelectric conversion element provided inside the substrate on the boundary region; a passivation layer provided on the substrate; a grid trench formed on the boundary region of the substrate and extending from an upper surface of the passivation layer toward an inside of the passivation layer; grid patterns, each of the grid patterns being provided on the passivation layer on each of the active pixel sensor region and the boundary region of the substrate, at least a part of a grid pattern being provided inside the grid trench; and a color filter provided between the grid patterns.
