LIGHT SOURCE UNIT, BACKLIGHT UNIT AND DISPLAY APPARATUS HAVING THE SAME

摘要

A light source unit capable of obtaining white light with reduced color irregularity includes a plurality of light-emitting diodes ( 25 R, 25 G and 25 B) having different emission spectrum peak wavelengths, and a light mixing member ( 21 ) that receives lights from the light-emitting diodes through an entrance surface ( 21 a) and that allows lights to mix together before exiting through an exit surface ( 21 b). The light mixing member ( 21 ) has anisotropic diffusing elements ( 22 ) that diffuse incident lights from the light-emitting diodes in a specific plane to effect light mixing.
