摘要： Optical bodies are described. In particular, optical bodies having a birefringent multilayer optical film and a continuous adhesive layer with a thickness less than 20 micrometers are described. Optical bodies described herein exhibit reduced occurrence and severity of a non-uniformity defect known as “orange peel.”

摘要： A backlight includes an extended light source adapted to emit light. A reflective polarizer is disposed on the extended light source, such that for substantially normally incident light and for at least a first wavelength in a range from about 420 nanometer (nm) to about 650 nm, the reflective polarizer reflects at least 60% of the incident light having a first polarization state and transmits at least 60% of the incident light having an orthogonal second polarization state. A first prismatic film is disposed between the extended light source and the reflective polarizer. A retarder layer is disposed between the reflective polarizer and the first prismatic film, such that for substantially normally incident light at a wavelength of about 550 nm, the retarder layer has a retardance nW, where n is an integer ≥1 and W is a wavelength between about 160 nm and about 300 nm.
