Abstract

The present invention relates to a LCD back light unit (BLU) used light diffusing plate. The invention provides a light diffusing plate laminated on a transparent plastic substrate. The front side of light diffusing layer is laminated on the front side of the said substrate andthe back side of light diffusing layer is laminated on the back of the said substrate. The front and back light diffusing layers have a more than 50% mist level. The light diffusing plate removes the bright line spot, uniformly scatters the light, thereby improving the view angle and providing clear display pictures.
