The invention discloses a collimated light source, its manufacturing method and a display device. The collimated light source comprises a base substrate, a film layer with a plurality of concave microstructures on the base substrate, and a reflective layer on the film layer. And a plurality of light-emitting parts corresponding to each concave microstructure one-to-one; wherein, after the light emitted by each light-emitting part is reflected by the reflective layer on the corresponding concave microstructure, it is parallel to the side of the reflective layer away from the substrate The light is emitted, thereby providing a collimated light source capable of emitting collimated light; in this way, the collimated light source can be used to provide a collimated backlight for the display panel, and the use of light-splitting technology enables the display panel to save the setting of the color filter layer Color images can also be displayed at the same time, so that the light energy loss of the display panel can be reduced, and the light extraction efficiency of the display panel can be improved, and accordingly, the power consumption of the display panel can be reduced. |
