Backlight with complex diffusers and flat panel display using the same
A flat panel display includes a backlight module, a liquid crystal display panel, and a complex diffuser plate. The liquid crystal display panel is disposed on the backlight module, and the complex diffuser plate including a first and a second diffusion layers is disposed between the backlight module and the liquid crystal display panel. Furthermore, the first diffusion layer is adjacent to the liquid crystal display panel and the second diffusion layer is adjacent to the first diffusion layer. The first and the second diffusion layers have different refractive indexes, transmittances and haze values, so that optical performance of the flat panel display is improved.
