Abstract
Disclosed is a backlight unit in order to suppress an increase of time needed for manufacture and generation of operation variance, and furthermore, to suppress deterioration and unevenness of luminance of output light. A plurality of transparent light guide plates (5), which are disposed in a chassis (4) in the lateral direction, and which output light emitted from a light source (7), are provided with a fixing protruding section (51) which is to be pressed by a fixing member (6), and an outputting section (52), which outputs planar light. The outputting section (52) is provided with, when viewed from the front, an extending section (53) which extends to cover at least a part of the fixing protruding section (51).
