Backlight device, liquid crystal display device and television receiver
Disclosed are a side light-type backlight device with high brightness and excellent light use efficiency, a liquid crystal display device and a television receiver. The disclosed backlight device has a light guide plate that emits, from the top surface, light that entered from the side surface thereof, a substrate that is disposed at the side surface of the light guide plate and that has a plurality of LEDs emitting light from the top aligned thereon, and an outer case enclosing the light guide plate and the substrate. Of the plurality of LEDs, the end LEDs are provided with inclined sections such that the illumination direction of said end LEDs intersect with that of the other LEDs.
1. A backlight device, comprising:
a light guide plate that emits, from a top surface thereof, light that entered from a side surface thereof;
a substrate that is disposed at the side surface of the light guide plate and that has a plurality of top-emitting LEDs arranged thereon; and
an outer case that encloses the light guide plate and the substrate,
wherein, of the plurality of LEDs, an LED at an end is provided with a tilting portion that makes an illumination direction thereof cross an illumination direction of other LEDs, and
wherein the tilting portion is provided by connecting the LED at the end to the substrate through a relay terminal that has an inclined top surface.
2. The backlight device according to claim 1 , wherein a light incident surface of the light guide plate has an inclined surface that is perpendicular to an illumination direction of the LED provided with the tilting portion.
3. A light crystal display device, comprising the backlight device according to claim 1 .
