    Abstract: Multilayer optical film reflective polarizers previously considered to have excessive off-axis color can provide adequate performance in an LC display in an "on-glass" configuration, laminated to a back absorbing polarizer of the display, without any light diffusing layer or air gap in such laminate. The reflective polarizer is a tentered-one-packet (TOP) multilayer film, having only one packet of microlayers, and oriented using a standard tenter such that birefringent microlayers in the film are biaxially birefringent. The thickness profile of optical repeat units (ORUs) in the microlayer packet is tailored to avoid excessive perceived color at normal and oblique angles. Color at high oblique angles in the white state of the display is reduced by positioning thicker ORUs closer to the absorbing polarizer, and by ensuring that, with regard to a boxcar average of the ORU thickness profile, the average slope from an ORU(600) to an ORU(645) does not exceed 1.8 times the average slope from an ORU(450) to the ORU(600).

    Abstract: An optical film includes a microstructured surface having a plurality of irregularly arranged planar portions forming greater than about 10% of the microstructured surface. The microstructured surface may be configured such that, when the microstructured surface is placed on an emission surface of a lightguide with a first luminous distribution of light exiting the lightguide from the emission surface in a first plane perpendicular to the emission surface, the light emitted by the lightguide is transmitted by the microstructured surface at a second luminous distribution of the transmitted light in the first plane. The first luminous distribution includes a first peak making a first angle greater than about 60 degrees with a normal to the microstructured surface. The second luminous distribution includes a second peak making a second angle in a range from about 5 degrees to about 35 degrees with the normal to the microstructured surface.
