Lighting device, display device and television receiver

Abstract

In a backlight unit, light from a light source is easily transmitted to a surface of a light guide plate opposite to a light entrance surface. A backlight unit 24 of the present technology includes an LED unit 32, a light guide plate 20 having a light entrance surface 20a on the side surface thereof and a light collecting member 38. The light collecting member 38 is provided between the LED unit 32 and the light entrance surface 20a and collects light from the LED unit 32 in a thickness direction of the light guide plate 20. The light collecting member 28 directs light from the LED unit 32 to the light entrance surface 20a effectively. Furthermore, the light collecting member 28 prevents light entering from the light entrance surface 20a from being dispersed in the thickness direction of the light guide plate 20 therein. Accordingly, light from the LED unit 32 is likely to be totally reflected within the light guide plate 20.
