Abstract: An optical film and a display are provided and including a substrate and microstructures. The microstructures are disposed on the substrate, wherein the microstructure includes first line segment portions and second line segment portions, and wherein in an extension direction of the microstructure, the first line segment portions and the second line segment portions are alternately arranged and connected to each other, and an extending direction of the first line segment portions intersects with an extending direction of the second line segment portions. The present application utilizes the microstructures disposed on the substrate to change the optical path of part of the light of the display screen, thereby weakening the phenomenon of light and dark stripes and moiré patterns caused by the periodic microstructures of the display screen.

Abstract: A polarizer includes a polarizing functional layer and a whisker arranged within the polarizing functional layer. After dyeing and stretching, the polarizing functional layer converts natural light into polarized light, and the whiskers are directionally arranged within the polarizing functional layer. The whisker has a long axis, and the extension direction of the long axis has an angle of −5 degrees to 5 degrees with the absorption axis of the polarizing functional layer. The present disclosure also provides a method for preparing a polarizer, and a display panel having a polarizer.
