Abstract
A light guide body configured to guide light that enters therein has a light exit surface through which light from the at least one light source exits, and a plurality of linearly arranged pattern groups, each of which has a plurality of linearly arranged reflection patterns that reflect the light from the at least one light source toward the light exit surface. At least one of the plurality of linearly arranged pattern groups differs from at least another of the plurality of linearly arranged pattern groups in light amount difference. The light amount difference is a difference between an amount of light which reaches an observer of the light exit surface after being reflected by each of the plurality of linearly arranged pattern groups and an amount of light which reaches the observer through a region which is adjacent to each of the plurality of linearly arranged pattern groups.
