A method for making a prismatic laminate includes the steps of: a) forming a back-coating roller having a roller surface with a plurality of recesses arranged in a predetermined pattern and produced by laser holography; b) preparing a prismatic structure including a plate body having a first surface and a second surface opposite to the first surface, and a plurality of prismatic strips formed on the first surface of the plate body; c) applying a coating containing a resin component and an antistatic agent on the second surface of the plate body; and d) embossing the coating with the back-coating roller to form an optical layer including a plurality of microstructures protruding in a direction away from the second surface of the plate body and having a pattern corresponding to that of the recesses in the roller surface.
