SURFACE LIGHT SOURCE DEVICE AND BACKLIGHT UNIT HAVING THE SAME

摘要

A surface light source device and a backlight unit having the same are provided to improve the uniformity of contrast even though the surface light source device is made of plural surface light source modules. A surface light source device comprises a light source body(110) containing a discharge space(140) into which the discharge gas is injected; a plurality of surface light source modules having an electrode(150) which applies a discharge voltage to the discharge gas; a light guide member guiding the light, which is emitted from the plural surface light source modules to downwards, to the border area between the surface light source modules. The light guide member is mounted at the bottom side of surface light source modules.
