Abstract: An optical member includes: a light guide portion; a three-dimensional effect forming portion; and a multi-effect forming portion. The three-dimensional effect forming portion comprises multiple main patterns sequentially arranged on the first surface in a first direction and having respective inclined surfaces. The multiple main patterns guide an incident beam to a first surface direction or a second surface direction, thereby creating a line-shaped beam of a first path crossing at right angles to each pattern extension direction of the multiple patterns. The multi-effect forming portion comprises multiple optical patterns sequentially arranged in a second direction crossing a first direction and configured for converting a single line-shaped beam of the first path into multiple line-shaped beams.
