1. A light detecting device, comprising:
first, second, third, and fourth pixels disposed adjacent to each other in a plan view, and
the first, second, third, and fourth pixels including first, second, third, and fourth photoelectric conversion regions,
wherein the first photoelectric conversion region is divided completely into two portions in the plan view, first and second portions, by a first separation region,
wherein the second photoelectric conversion region is divided completely into two portions in the plan view, third and fourth portions, by a second separation region,
wherein the third photoelectric conversion region is divided completely into two portions in the plan view, fifth and sixth portions, by a third separation region,
wherein the fourth photoelectric conversion region is divided completely into four portions in the plan view, seventh, eighth, ninth, and tenth portions, by a fourth separation region,
wherein the fourth separation region is a cross shape in the plan view,
wherein the first, second, third, and fourth pixels are disposed in a 2×2 array, and
wherein each of the first, second, third and fourth separation regions extends from a first surface of each of corresponding first through tenth portions of the first through fourth photoelectric conversion regions to a second surface of each of the corresponding first through tenth portions of the first through fourth photoelectric conversion regions without extending beyond the first surface and the second surface of the corresponding first through tenth portions of the first through fourth photoelectric conversion regions in a cross-sectional view.
