Provided is a backlight unit comprising: a light source capable of emitting light; and a light guide plate containing a peripheral surface which receives light from the light source, a main surface (14) which is provided connected to the peripheral surface, and a main surface (15) which faces the main surface (14) with the peripheral surface positioned therebetween. The light guide plate (10) includes: a reflective surface (22) which is capable of reflecting, toward the main surface (14), light that is input from the peripheral surface; and a lens (23) which is formed on the main surface (14) and can condense the light reflected by the reflective surface (22) and emit the light to the outside. |
