Abstract
A backlight device is provided with the following: LEDs; a light guide plate formed in a rectangular plate shape and having at the end surfaces thereof a light-receiving face opposing the LEDs and a reflection surface disposed on the side opposite the light-receiving face, and having on the plate surface thereof a light-emitting surface that emits light; a portion to be supported provided to the corner part, from among the corner parts of the light guide plate, that is disposed on the opposite surface side; a supporting portion that supports the light guide plate in a first direction and a second direction by coming into contact with the portion to be supported, when the first direction is a direction in which the LEDs and the light guide plate are lined up, and the second direction is a direction that is orthogonal to the first direction and that follows along the light-emitting surface of the light guide plate; and a inclined portion that is provided to the portion to be supported and that forms a slanted shape with respect to both the first direction and the second direction, and by facing outward in the second direction is distanced from the LEDs in the first direction.
