Optical assembly and the method to make the same
The present invention discloses an optical assembly. The optical assembly comprises a first optical film, a second optical film and an adhesive layer between the first optical film and the second optical film. The top surface of the adhesive layer is disposed on the bottom surface of the first optical film. The adhesive layer comprises a plurality of first acrylate functional groups. The second optical film comprises a plurality of microstructures. Each of the plurality of microstructures has a top planar portion having a plurality of second acrylate functional groups. The top planar portion is bonded to the bottom surface of the adhesive layer through a chemical bonding between the plurality of first acrylate functional groups and the plurality of second acrylate functional groups without making the top planar portion penetrate into the adhesive layer.
