A backlight unit (5) according to one embodiment of the present invention, wherein an LED light source (3) is disposed directly below a liquid crystal panel (2), said backlight unit (5) comprising an anisotropic sheet (22) between the LED light source (3) and the liquid crystal panel (2). The anisotropic sheet (22), which transmits light emitted from the LED light source (3) and diffuses the emitted light towards the liquid crystal panel (2), has a structure which causes the emitted light to diffuse more widely in the direction along the long sides of a display surface in comparison to the direction along the short sides thereof. By providing this kind of anisotropic sheet (22), a reduction in brightness towards the short sides of the display surface can be suppressed with respect to light which radiates a unit area that is, for example, rectangular or the like. |
