Abstract

Provided is an electronic package (PG) which is made without using screws or double-sided adhesive tapes, so cost can be reduced and the manufacturing process can be made simpler. This is done by configuring the electronic package (PG) so that a backlight chassis (10) thereof includes anchoring claws (11) for fixing a mounted substrate (21) onto itself. A lighting device (backlight unit (49)) and a displaying device (liquid crystal display device (69)) are provided with this electronic package (PG).

Claims

1. An electronic package comprising:

a chassis; and

a mounting board which is fitted to the chassis,

wherein the chassis itself includes a fastening portion for fastening the mounting board.

2. The electronic package according to claim 1,

wherein the fastening portion is hook-shaped, rising from a bottom surface of the chassis and bent toward the bottom surface.

3. The electronic package according to claim 2,

wherein, in a case where the hook-shaped fastening portion, at a rising segment which is a portion of the fastening portion rising from the bottom surface of the chassis, makes contact with an edge of the mounting board,

a plurality of the fastening portion are arranged at opposite edges of the mounting board.

4. The electronic package according to claim 2,

wherein the hook-shaped fastening portion includes a rising segment which is a portion of the fastening portion rising from the bottom surface of the chassis and an overhanging segment which is a portion of the fastening portion crossing the rising segment and overhanging a mounting surface of the mounting board, and

a projection for increasing a pressing force against the mounting surface is formed on the overhanging segment.

5. The electronic package according to claim 4,

wherein the mounting board includes a hole in which the projection on the overhanging segment fits.

6. The electronic package according to claim 2,

wherein the hook-shaped fastening portion is formed by cutting and raising part of the bottom surface of the chassis.

7. The electronic package according to claim 1,

wherein the bottom surface of the chassis has a window to be shaped like a skeleton.

8. The electronic package according to claim 1,

wherein the chassis is made of aluminum alloy or carbon fiber-reinforced plastic.

9. The electronic package according to claim 1,

wherein at least part of the chassis is coarse-surfaced.

10. The electronic package according to claim 9,

wherein the coarse-surfaced part of the chassis is on a surface of the chassis facing outward.

11. The electronic package according to claim 1,

wherein at least part of the chassis has high-emissivity paint applied thereto.

12. The electronic package according to claim 11,

wherein the high-emissivity paint-applied part of the chassis is on a surface of the chassis facing outward.

13. An illuminating device comprising:

the electronic package according to claim 1; and

a light source which is mounted on the mounting surface of the mounting board.

14. The illuminating device according to claim 13,

wherein a reflective sheet covers the mounting surface, with a reflective surface of the reflective sheet facing outward and a reverse surface to the reflective surface facing the mounting surface, and

the reflective sheet has a perforation formed therein to expose only a light-exit region of the light source where the light source emits light.

15. A display device comprising:

an illuminating device according to claim 13; and

a display panel which receives light from the illuminating device.
