Abstract: Provided are an optical member capable of implementing optical images having desired shapes through a pattern design, and a lighting device using the optical member, the optical member including: a base substrate; multiple patterns sequentially arranged on a first surface of the base substrate and having inclined surfaces with an inclination angle with respect to the first surfaces; and a reflective portion on the base substrate or the multiple patterns, wherein the multiple patterns implement a line shaped beam of a first path crossing at right angles to respective pattern extension directions of the multiple patterns by guiding a first incident beam into a first surface direction toward which the first surface looks or a second surface direction toward which a second surface of the base substrate opposite to the first surface looks, through refraction or reflection from the inclined surfaces.
