Publication number: 20230314683Abstract: An optical stack includes a reflective polarizer, an absorbing polarizer, and a half-wave retarder. The half-wave retarder is disposed between the reflective and absorbing polarizers. For substantially normally incident light and a first polarization state, the reflective polarizer reflects at least about 60% of the incident light for at least a first wavelength less than a cut-off wavelength and transmits at least about 50% of the incident light for at least a second wavelength greater than the cut-off wavelength. For substantially normally incident light, the half-wave retarder has a first retardance of less than about 250 nanometers (nm) at the first wavelength and a second retardance at the second wavelength. A deviation of the first retardance from a first half-wave retardance corresponding to the first wavelength is less than a deviation of the second retardance from a second half-wave retardance corresponding to the second wavelength.Type: ApplicationFiled: July 29, 2021Publication date: October 5, 2023Inventors: Adam D. Haag, Sun-Yong Park, Martin E. Denker
