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).
