Abstract
Provided is an optical guide bar including: a light exit portion; light incident portions, on which light is incident, formed on both sides of the light exit portion; and a reflective portion facing the light exit portion and including a prism pattern that reflects light transmitted through the light incident portions towards the light exit portion. A shape of the reflective portion is determined in consideration of an effective light emission width of the light incident portion so that the intensity of light at any portion of the reflective portion is uniform.
