An apparatus for manufacturing a light guide film may comprise a feed roller, a receiving roller, a separating device, a hot press printing device and a recombining device. Firstly, the separating device may separate a protective layer from a substrate layer of the light guide film. Secondly, a surface of the substrate layer to be manufactured may be impressed with light guide dots by the hot press printing device, and the recombining device recombine the peeled protective layer to the substrate layer. And lastly, the finished light guide film is recycled by the receiving roller. The apparatus may have advantages such as high output and low cost, and it may manufacture a large dimensioned product.
