Abstract:
A light emitting element array includes plural semiconductor stacking structures and a light screening portion. The plural semiconductor stacking structures each include a light emitting portion and a light receiving portion that receives light propagated in a lateral direction via a semiconductor layer from the light emitting portion. The light screening portion is provided between the plural semiconductor stacking structures to screen light directed from the light emitting portion of one of the semiconductor stacking structures to the light receiving portion of another semiconductor stacking structure.
