Abstract
An exit surface of a light guide plate includes 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 the vicinity thereof 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 the vicinity thereof. A straight line that passes through the first position and the center of the one eye and a straight line that passes through the second position and the center of the other eye intersect with each other.
Claims8
A light guide body comprising:
- reflection patterns, each of which reflects light emitted from at least one light source and that 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 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 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 the observer intersect with each other.
