ILLUMINATION DEVICE, DISPLAY DEVICE, AND TELEVISION RECEPTION DEVICE

摘要

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.

主权项

1. An illumination device, comprising:
a light source; a light guide plate having a rectangular shape including a light-receiving side face facing the light source, said light guide plate further having a surface that is a light-emitting surface that emits light and a portion to be supported that is provided at a corner area of the light guide plate on a side of the light guide plate opposite the light-receiving side face; and a supporting member that supports the light guide plate in a first direction and a second direction by abutting the light guide plate at the portion to be supported, said second direction being a direction parallel to the light-receiving side face of the light guide plate, said first direction being a direction perpendicular to the second direction in a plan view, wherein at least one of the portion to be supported and the supporting member has a structure extending in a direction that is angled relative to the first direction and the second direction, the structure extending generally outwardly relative to a center of the light guide plate.
