An optical film, a light-emitting device and a display device are provided. The optical film includes a quantum rod film layer and a light transmission prism layer located on a light emergent side of the quantum rod film layer. The prism layer is configured at the light emergent side of the quantum rod film layer to converge the linearly polarized light transmitted by the quantum rod film layer, so that the brightness of the light located at the light emergent side of the whole optical film is increased.

Techniques, devices and materials for light source devices that convert excitation light into different light via wavelength conversion materials. One example of a light source includes an excitation light source; a wavelength conversion material that absorbs light from the excitation light source and emits a longer wavelength light; and a layer of a transparent material that has plural optical structures in contact to or in close proximity to the wavelength conversion material to receive the emitted light from the wavelength conversion material and to modify the received light to produce output light with a desired spatial pattern associated with the plural optical structures.
