ABSTRACT:
A back light device 10 comprises a light source 12, a lightconductor 14 for outputting light from the light source from its outputting surface 14B, a light diffusing sheet 16 for receiving diffused light from the lightconductor 14 and shifting the maximum intensity direction to the direction of the normal standing on the light outputting face 16B, a polarized beam splitting sheet 18 through which one polarized light component among the light from the light diffusing sheet 16 is transmitted and on which the other polarized light component is reflected.
