<p>In order to suppress variations in brightness in outgoing planar light as well as reduce the number of constituent components and reduce the costs required for production and assembly, a backlight unit (1) is provided with a light shielding part (6) having a reflective layer (62), which is joined integrally to an end part on a light source unit (3) side of an optical sheet (4) and reflects light, and a light absorbing layer (61), which is disposed on the side opposite to a light guide plate (2) sandwiching the reflective layer (62) therebetween and blocks light.</p> |
