The impact of Fresnel's reflection from a clear optical film, a polarizer, and a reflective polarizer on light recycling in a variety of LCD backlight configurations is investigated. It is found that Fresnel's reflection plays an important role in on‐axis and off‐axis gain, and this reflection results in higher gain at an angle near Brewster's angle in a horizontal plane in the presence of a polarizer with its pass axis in the horizontal plane.
