— In this paper, an LCD backlight with holographic diffusers as the top diffuser was investigated. Using a suitable elliptical holographic diffuser, the moiré pattern was eliminated and the brightness of the backlight was increased up to 15% compared to that for a backlight with a conventional diffuser. A Monte Carlo simulation was also applied to compare with the experimental results. In addition, elliptical diffusers can be applied to modify the viewing cone of the backlight.
