Summary:An optical film with low or zero birefringence and a method for fabricating the same are provided. The optical film with low or zero birefringence includes a plurality of birefringence films, and the plurality of birefringence films is overlapped with the long axes perpendicular to each other. A sum of the refractive indices of the overlapped birefringence films in an x direction is equal to that in a y direction. The placement of the birefringence films in the optical film with low or zero birefringence can solve the problem that optical polymer cannot be applied to optical parts due to the birefringence of optical polymer.
