Abstract: An optical film for a display device, includes: a first refractive layer having an upper surface and a lower surface including first projections and second projections extending away from the lower surface in a first direction, the second projections having different heights than the first projections, the first projections having lateral sides with different angles of inclination that decrease in the first direction; and a second refractive layer disposed directly on the upper surface of the first refractive layer, the second refractive layer having a refractive index different from that of the first refractive layer.
