ABSTRACT:
An electro-optical element is provided including a light-emitting element part and a light-receiving element part. An electro-optical element includes a light-emitting element part and a light-receiving element part having an optical surface and formed on the light-receiving element part. The electro-optical element emits light at least in a direction that the light-emitting element part and the light-receiving element part are formed in layers. In addition, an optical member is formed at least on the optical surface.
