Light guide body and light-emitting device

A light guide body comprising:

• a plurality of reflection patterns, each of which reflects light emitted from at least one light source and enters the light guide body through a side surface of the light guide body;
• and
• an exit surface through which light reflected from each of the plurality of reflection patterns is emitted,
• wherein the exit surface comprises:
• a first position from which first emitted light is emitted within an angular range that causes the first emitted light to be applied to one eye and a vicinity thereof of an observer observing the exit surface;
• and
• a second position from Which second emitted light is emitted within an angular range that causes the second emitted light to be applied to the other eye and a vicinity thereof of the observer,
• wherein one of the plurality of reflection patterns emits the first emitted light and another one of the plurality of reflection patterns emits the second emitted light,
• wherein a straight line which passes through the first position and a center of the one eye of the observer and a straight line Which passes through the second position and a center of the other eye of the observer intersect with each other at an intersection so that a real image point is displayed at the intersection, and
• wherein an object corresponding to an arrangement of the plurality of reflection patterns is stereoscopically displayed before or behind the exit surface in such a manner that, in order to display a plurality of the real image points which are arranged together, the plurality of reflection patterns are arranged so as to provide a plurality of the intersections, so that a group of the plurality of real image points are formed.
