In one embodiment, a brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The brightness enhancement film is capable of collimating light, and wherein, without the coating, the diffusing film would be capable of spread light passing through the back surface. In another embodiment, the brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The diffusing film has a stress retardation gradient of less than or equal to 50 nm/in, wherein an interval for calculation of the stress retardation gradient is less than 1 inch. The brightness enhancement film is capable of collimating light.
