A lighting unit capable of reducing loss of light from light sources and a liquid crystal display device are provided. A lighting unit (40), whereby light from light sources (61) is reflected, the reflected light is caused to enter one side surface of a light guide plate (80), and the incident light is caused to exit from one surface of the light guide plate (80), is equipped with: a reflective section (96) which has an internal hollow part extending in the direction of the long side of the one side surface of the light guide plate (80) with a cross-section of the hollow part in the perpendicular direction to the long-side direction of the one side surface being formed into a round shape; and multiple light sources (61) which are arranged in the long-side direction of the one side surface along the outer surface of the reflective section (96). The reflective section (96) has a first aperture (94) for the light from the multiple light sources (61) to enter therein and a second aperture (95) for the light which has entered through the first apertures (94) and has been reflected off the inner surface of the reflective section to exit toward the one side surface of the light guide plate (80). The reflective section is further equipped with a light-shielding section (93) which blocks the light which has exited through the second aperture (95) from leaking to the outside of the one side surface of the light guide plate (80). |
