LIGHTING APPARATUS, DISPLAY APPARATUS, AND TELEVISION RECEIVER
First Claim
1. An illumination device, comprising:
- a light source;
a light guide plate that faces said light source and that has a light incident face on which light from said light source is incident and a light exiting surface from which light exits;
an optical sheet arranged on a side of said light guide plate adjacent to the light exiting surface thereof;
a chassis formed by bending a metal plate and arranged on a side of said light guide plate opposite to the light exiting surface thereof, said chassis being constituted of a plate portion that extends along said light guide plate, a first extending portion that continues from the plate portion and extends in a direction opposite to the light guide plate and that forms a first corner portion with said plate portion, and a height-difference portion that forms a second corner portion with said first extending portion and provides a difference in height with respect to the plate portion; and
a heat dissipating member that dissipates heat from the light source, said heat dissipating member being constituted of a light source attachment portion to which said light source is attached and a chassis contacting portion that is contiguous with said light source attachment portion and in contact with said height-difference portion from a side opposite to the light guide plate.

Abstract
A backlight apparatus includes LEDs; a light guide plate; an optical member; a chassis formed by bending a metal plate material, the chassis including a bottom plate (plate portion) that extends along the light guide plate, a rising portion (first extending portion) that rises from the bottom plate on an opposite side to the light guide plate and forms a first corner portion with the bottom plate, and a height-difference portion that forms a second corner portion with the rising portion and provides a height-difference portion with respect to the bottom plate; and a heat dissipating member that dissipates heat of the LEDs, the heat dissipating member including a light source attachment portion to which the LEDs are attached and a chassis contacting portion that is contiguous with the light source attachment portion and is in contact with the height-difference portion from the opposite side to the light guide plate.
