The invention discloses an optical splitter, an optical communication system using the optical splitter and a display device. The optical splitter comprises a light transmission substrate and a plurality of microstructure unit groups, wherein two directions which are parallel to a surface of the light transmission substrate and are vertical to each other are defined as an X direction and a Y direction; and the microstructure unit groups with a same structure are arranged on the substrate surface and are periodically arranged at the X direction and the Y direction so as to form a super-surfacestructure. Each microstructure unit group includes a plurality of microstructure units. Each microstructure unit includes a plurality of micro-nano columns which are parallel to each other and are arranged at intervals. Heights of the plurality of micro-nano columns are the same and cross section sizes carry out a gradient change along an arrangement direction. And gradient directions of the plurality of microstructure un
