For a visible wavelength range extending from about 420 nm to about 680 nm and an incident light propagating in an incident plane that includes a x-direction, and for an s-polarized incident light, the multilayer partial mirror has an average reflectance Rs1 for a first incident angle of less than about 10 degrees, and an average reflectance Rs2 for a second incident angle of greater than about 45 degrees, and for a p-polarized incident light, the multilayer partial mirror has an average reflectance Rp1 for the first incident angle, and an average reflectance Rp2 for the second incident angle. Each of Rs2/Rs1 and Rp2/Rp1 is greater than about 1.15.

Abstract: An optical film includes a plurality of alternating first and second layers. The first layers have a first in-plane birefringence, the second layers have a second in-plane birefringence, and the second in-plane birefringence is less than the first in-plane birefringence and greater than 0.03. The first layers may include polyethylene terephthalate homopolymer and the second layers may include glycol-modified co(polyethylene terephthalate). The optical film has a shrinkage along a first direction of greater than 4% and a shrinkage along an orthogonal second direction of greater than 3% when heated at 150° C. for 15 minutes. A glass laminate is prepared by disposing the optical film between glass layers and laminating the optical film to the glass layers.

Abstract: A display (1000) including a display panel (130) and a polarizer (110) disposed to receive a light (150) output of the display panel (130) is described. The polarizer (150) may be a reflective polarizer (110) or a circular polarizer (100) incorporating a reflective polarizer (110). The display panel (130) includes a plurality of pixels and each pixel includes a plurality of subpixels. The reflective polarizer (110) has a first reflection band, wherein at normal incidence, the first reflection band has a long wavelength band edge wavelength between peak emission wavelengths of two subpixels in the plurality of subpixels. The reflective polarizer (110) may be disposed between an absorbing polarizer (106) and a retarder (108) in a circular polarizer (100). The reflective polarizer (110) may have substantially non-overlapping first, second, and third reflection bands.

Abstract: The present disclosure provides a reflective polarizer including a plurality of polymeric first layers and a plurality of polymeric second layers. A plot of an average layer thickness versus a layer number for the pluralities of polymeric first, but not second, layers includes a knee region separating a left region including at least 50 sequentially arranged polymeric first layers. The polymeric first layers have lower layer numbers, and the average layer thickness increases with increasing layer number from a right region including at least 5 sequentially arranged polymeric first layers. The polymeric first layers have higher layer numbers and the average thickness increases with increasing layer number, such that linear fits to the at least 50 sequentially arranged polymeric first layers and to the at least 5 sequentially arranged polymeric first layers have respective positive slopes S1 and S2, S2/S1≥5.

Each region of the optical film that is disposed between a blue light emitting source and the corresponding blue light emitting pixel transmits at least 70% of substantially normally incident light having the blue peak wavelength. Each region of the optical film that is disposed between a blue light emitting source and the corresponding green or red light emitting pixel reflects at least 50% of substantially normally incident light having the blue peak wavelength.
