Abstract:
Optical film stacks are described. More particularly, optical film stacks including a half-wave retardation layer are described. Achromatic half-wave retardation layers, including achromatic half-wave layers formed from a quarter-wave and a three-quarters-wave retardation layer, are described. Film stacks including reflective polarizers tuned to reduce wavelength dispersion of the half-wave retardation layer are also described.

Claim (Index 1):
An optical film stack, comprising:\n a tuned reflective polarizer having a top surface, a bottom surface, a transmission axis, and a reflection axis; a half-wave retardation layer having a top surface, a bottom surface disposed on the top surface of the reflective polarizer, and a slow axis oriented substantially 45\u00b0 with respect to the transmission axis of the reflective polarizer; and an absorbing polarizer having a bottom surface disposed on the top surface of the achromatic half-wave retardation layer and a transmission axis oriented substantially 90\u00b0 with respect to the transmission axis of the reflective polarizer; wherein the tuned reflective polarizer is tuned to reduce wavelength dispersion of the half-wave retardation layer.
