Abstract
The present invention relates to a method for manufacturing a spatially limited film stack comprising an optically anisotropic film on an optical sensor device with a light sensor element, such that the film stack covers the light sensor element but not the entire surface area of the optical sensor device. An electronic device manufactured according to the method of the invention can be used for analyzing the polarization state of light.
