Abstract
A transfer printing apparatus includes a mold, a stamper, a pressing roller and a curing unit. The mold has a first surface with first and second concavities, the second concavity has first and second planes, the first plane is perpendicular to the first surface, and the second plane is inclined to the first surface. The stamper having a second surface is disposed in the first concavity. The first and second surfaces are coplanar, and the second surface has transfer printing microstructures. The first and second surfaces are suitable for coated an adhesive layer. The pressing roller presses a base film onto the adhesive layer, such that the adhesive layer is integrated with the base film. The curing unit cures the adhesive layer on the base film, such that a taper corresponding to the second concavity and optical microstructures corresponding to the transfer printing microstructures are formed on the adhesive layer.
