Disclosed herein is an optical article having a top layer with a
structured surface that collimates light, a core layer secured to the top
layer opposite the structured surface, and a bottom layer secured to the
core layer opposite the top layer. Either the top layer or the core layer
includes a first extrudable polymer having a flexural modulus of greater
than 2.5 GPa, and the other layer includes a second extrudable polymer
having a flexural modulus of 2.5 GPa or less, an impact strength of
greater than about 40 J/m, and tensile elongation at break of greater
than about 5%. The bottom layer includes a third extrudable polymer. The
bottom layer of the optical article may be structured to diffuse light.
One or two optical articles may be secured to an optical film such as a
polarizer film. Methods and display devices are also disclosed herein.
