Abstract: A manufacturing method of a light guide plate. A transparent plate is provided, wherein a surface of the transparent plate has a plurality of first optical microstructures. Then, a first hot pressing roller having a plurality of transfer printing microstructures is provided. A plurality of second optical microstructures are formed on the surface through the transfer printing microstructures by the first hot pressing roller. At least a part of the second optical microstructures is not overlapped with the first optical microstructures.
