Abstract
A side emitting device, a backlight unit using the same as a light source, and a liquid crystal display (LCD) employing the backlight unit. The side emitting device includes a light-emitting device to emit light, and a side emitter to change the path of at least part of the light emitted from the light-emitting device. The side emitter includes a first reflecting surface reflecting light emitted from the light-emitting device in a first range of angles close to a central axis, a first refracting surface refracting the light reflected by the first reflecting surface obliquely downward from the horizontal axis, and a second refracting surface refracting light emitted from the light-emitting device in a second range of angles complementary to the first range of angles. The backlight unit includes at least an array of side emitting devices, a reflection diffusion plate and a first transmission diffusion plate.
