Abstract

An illumination device or the like is provided that reduces variations in the position of a member incorporating light sources such as LEDs and that reduces the size of the member and thus achieves the size reduction. In the illumination device, a plurality of mounting substrates (11) are arranged close to each other, and the mounting substrates (11) are regular hexagonal.

Claims

1. An illumination device that includes light sources and a plurality of mounting substrates having the light sources arranged,

wherein the mounting substrates are arranged close to each other, and the mounting substrates are regular hexagonal.

2. The illumination device of claim 1,

wherein connectors, each including a positive terminal electrically continuous to a positive pole of one of the light sources and a negative terminal electrically continuous to a negative pole of the light source, are attached to a perimeter of one of the mounting substrates, and

the terminals of like poles of the connectors in the adjacent mounting substrates are electrically continuous.

3. The illumination device of claim 1,

wherein the light source is a light emitting element.

4. The illumination device of claim 3,

wherein, as a plurality of the light emitting elements, a red light emitting element, a green light emitting element and a blue light emitting elements are provided so as to be mixed.

5. The illumination device of claim 3,

wherein a plurality of the light emitting elements are white light emitting elements.

6. The illumination device of claim 1, further comprising:

an electric power adjustment portion that adjusts an amount of power supplied to the light sources.

7. The illumination device of claim 1, further comprising:

a diffusion member that diffuses light from the light sources.

8. The illumination device of claim 1, further comprising:

a brightness enhancement member that enhances brightness by transmitting the light from the light sources.

9. A display device comprising:

the illumination device of claim 1; and

a display panel that receives light from the illumination device.

10. The display device of claim 9,

wherein the display panel is a liquid crystal display panel.
