Zusammenfassung:	A backlight device and a liquid crystal display are provided. A liquid crystal display apparatus including a direct backlight device which has an LED assembled into a light-guiding plate and in which an brightness uniformity is controlled or improved is provided by controlling or improving the brightness uniformity. A backlight device 10 includes a light emitting diode 21 as a light source assembled into a light-guiding plate 30, in which an edge portion 32 on the bottom surface 30B side of a concave portion 31 in a light-guiding plate 30, where the light emitting diode 21 is assembled, is formed at to have the shape of an inclined or curved surface that has an angle except a right angle with respect to the bottom surface 30B.
