Abstract
A semiconductor device includes: a first layer including a first optical semiconductor element; a second layer including a second optical semiconductor element having a lower conversion efficiency than the first optical semiconductor element; and a lens member. The first optical semiconductor element and the second optical semiconductor element are disposed between the lens member and a focal point of the lens member in an optical axis direction of the lens member, at least partially overlap as viewed in the optical axis direction, and are disposed so that the second optical semiconductor element is closer to the focal point than the first optical semiconductor element.
