    摘要： A backlight unit and a liquid crystal display (LCD) apparatus employing the backlight unit. The backlight unit includes a plurality of light-emitting device units disposed on a base plate in an array, each light-emitting device unit including a collimator to collimate light emitted by a light-emitting device so that the light propagates in a principal propagation direction of light emitted from light-emitting device, a plurality of side reflectors disposed in an array above the array of corresponding light-emitting device units and to reflect lateral light incident from the corresponding light-emitting device units, a reflective diffusion plate to reflect and diffuse light incident from the side reflectors, and a transmissive diffusion plate that is disposed above the light-emitting device units, to transmit and diffuse the incident and reflected light.

    摘要： 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.
