| description | PROBLEM TO BE SOLVED: To provide a liquid crystal display whose luminance is improved by suppressing luminance unevenness in a direct type backlight apparatus wherein LEDs are mounted on a light guide plate. SOLUTION: In the backlight apparatus 10 which has light emitting diodes 21 as light sources and wherein the light emitting diodes 21 are mounted on the light guide plate 30, recessed parts 31 on which the light emitting diodes 21 of the light guide plate 30 are mounted are so constituted that each edge part of the recessed part 31 on a bottom surface 30B side of the light guide plate 30 has a shape having an inclined or curved surface having an angle except an angle vertical to the bottom surface 30B.
