ILLUMINATION DEVICE, DISPLAY DEVICE, TELEVISION RECEIVING DEVICE

摘要

A backlight device of the present invention includes: a chassis having a bottom plate; a plurality of LED substrates 25 that are rectangular and that are arranged such that one end face on the short side of the LED substrate 25 faces the short side of the bottom plate; LEDs arranged on the LED substrates 25; first through holes that go through the LED substrates 25; second through holes 42 that are disposed nearer the end face of the LED substrate 25 than the first through holes 41, that go through the LED substrates 25, and that are horizontally longer than the first through holes 41 along the long side direction of the LED substrates 25; plate-shaped through holes disposed in the bottom plate; and securing pins that have a size that enables the LED substrates 25 to be secured in the plate surface direction thereof by the securing pins going through the first through holes 41 and plate-shaped through holes, that secure the LED substrates 25 in the short side direction thereof by going through the second through holes 42 and plate-shaped through holes, and that are a size allowing the LED substrates 25 to move in the long side direction thereof.

主权项

1. An illumination device, comprising:
a chassis having at least a plate-shaped portion; a plurality of light source substrates that are rectangular and arranged on a surface of the plate-shaped portion such that at least an end face of a short side of each of the light source substrates faces an edge of the plate-shaped portion; light sources arranged on the light source substrates, a surface of each of the light sources on the plate-shaped portion side being a light-emitting side; first through holes penetrating the light source substrates; second through holes that, in a plan view of the plate-shaped portion, are disposed more in the vicinity of said end face of the respective light source substrates than the first through holes, the second through holes penetrating the light source substrates and being more horizontally elongated than the first through holes along a long side direction of the light source substrates; through holes in the plate-shaped portion that are disposed in the plate-shaped portion respectively corresponding in position to the first through holes and the second through holes; and securing pins that have a size that allows the light source substrates to be secured in a plate surface direction thereof by the securing pins going through the first through holes and the through holes in the plate-shaped portion, the securing pins securing the light source substrates in the short side direction thereof by going through the second through holes and the through holes in the plate-shaped portion, the securing pins having a size that allows the light source substrates to move in the long side direction thereof.
