摘要： Light beams are outputted from optical devices and mixed together to obtain uniform white light free from color stains, thereby achieving a backlight unit improved in light mixing feature. In the backlight unit, a surface light source has a reflecting surface with a plurality of optical devices mounted thereon. An optical sheet is disposed in front of the surface light source. A reflecting layer is disposed between the surface light source and the optical sheet and has reflectivity varied by an incident angle of light beams from the optical devices. The backlight unit enables the light beams from the optical devices to be mixed together. The light beams outputted from the optical devices are effectively mixed together by a reflecting layer having reflectively varied by an incident angle of the light beams from the optical devices, thereby achieving uniform white light without color stains.
