Abstract
An optical structure and a display device are provided. The optical structure includes a lens, a transflective film, a phase retardation film and a reflective polarizing film. The lens includes a first surface and a second surface which are non-planar surfaces; the transflective film is located at a side of the first surface away from the second surface; the phase retardation film and the reflective polarizing film are located between the phase retardation film and the second surface. The optical structure further includes a phase compensation structure located between the transflective film and the second surface. The phase compensation structure includes first light-transmitting layers and second light-transmitting layers which are alternately arranged and equal in number, a refractive index of the first light-transmitting layer is greater than that of the second light-transmitting layer; and the first light-transmitting layer is attached with the phase retardation film.
