<p>The present invention provides a side emitting lens that may reduce optical loss and improve light emitting ratios, and a backlight unit and liquid crystal display including the side emitting lens. The side emitting lens may have a substantially dome-shaped body. The body includes a base part on which external light is incident, a refracting part to refract incident light and emit the light from side surfaces, and a reflecting part. The reflecting part is in the shape of a conical recess at a central portion of the refracting part to fully reflect the incident light toward one of the refracting part and the base part and the reflecting part comprises two or more reflecting surfaces. Each of the two or more reflecting surfaces is a curved surface.</p> |
