BACKLIGHT UNIT AND LUMINOUS FLUX CONTROL MEMBER FOR LOCAL DIMMING

A backlight unit is disclosed which is capable of diffusing light emitted from a light source uniformly and suppressing white spot phenomenon. The backlight unit includes a light guide panel having a first surface and a second surface opposite to the first surface, a concaved light receiving region formed on the first surface, a light intensity adjusting recess formed on the second surface, a light intensity adjusting sheet disposed on the light intensity adjusting recess and the second surface around the light intensity adjusting recess. The backlight unit includes a substrate on which a plurality of light emitting devices are disposed, a plurality of luminous flux control members which are disposed on the substrate corresponding to the light emitting devices such that the light from the light source is uniformly transmitted upward, and a shade layer which is disposed between the luminous flux control members to reflect a portion of the light emitted through the luminous flux control member.
