ABSTRACT:
The invention relates to a method of manufacturing an optical component. In this method, a substrate, for example of glass, is successively provided with an orientation layer and an optically anisotropic layer of a material containing monomers which are provided with at least one covalently bonded reactive group, whereafter the optically anisotropic layer is polymerized. In accordance with the present invention, the applied orientation layer also comprises covalently bonded reactive groups. As a result, a good adhesion between the optically anisotropic layer and the orientation layer of the substrate is achieved. This has a favorable effect on the optical quality of the component. For the reactive groups use is preferably made of (meth)acrylate compounds which are polymerized by exposing them to radiation. Good results are achieved if for the orientation layer use is predominantly made of polyimide with covalently bonded reactive groups. Preferably, a glass plate is used as the substrate, and a bonding layer based on an organosilane compound is provided between the substrate and the orientation layer.
