Abstract

A side light-emitting device, a backlight unit using the side light-emitting device as a light source, and a liquid crystal display (LCD) apparatus employing the backlight unit. The side light-emitting device includes a light-emitting device to generate light and a side emitter disposed adjacent to the light-emitting device to emit the light incident from the light-emitting device in a lateral direction. The side emitter includes a reflecting surface to reflect incident light, and a reflecting/refracting surface to totally internally reflect light incident directly from the light-emitting device to the reflecting surface and to refract the light incident from the reflecting surface so that the refracted light propagates in the lateral direction. Since the side light-emitting device emits most the light in the lateral direction, using the side light-emitting device as a light source in a backlight unit allows light to be mixed evenly.
