Abstract
Provided are an optical member capable of implementing optical images having a desired shape and a lighting device using the optical member. The optical member can include a base substrate and a plurality of unit patterns sequentially arranged on a first surface of the base substrate and each having an inclined surface with respect to the first surface. Each unit pattern can be extended in a pattern extension direction, respectively. The plurality of unit patterns and the inclined surfaces thereof can be structurally arranged on the first surface of the base substrate such that any beam of incident light that strikes a unit pattern at a right angle to the pattern extension direction in which said unit pattern extends is guided away from the optical member.
