摘要： A backlight unit 24 of the present invention includes an LED light source 28, a light guide plate 20 and a lens member 26. The light guide plate 20 is configured to guide light that enters a light entrance surface 20a from the LED light source 28. The light entrance surface 20a has an elongated shape on the side surface thereof. The lens member 26 covers a light exit side of the LED light source 28 and is configured to diffuse light from the LED light source 28. The lens member 26 faces the light entrance surface 20a of the light guide plate 20 and is curved in the long-side direction of the light entrance surface 20a such that the lens member 26 bulges out toward the light guide plate 20 in a convex manner. The lens member 26 spreads light emitted from the LED light source 28 in the long-side direction of the light entrance surface 20a. This reduces a dark portion formed in the light entrance surface of the light guide plate 20.
