Abstract:
A light guide system (light guide device) includes a transparent light guide portion that guides light beams incident from one end side to a light-emitting portion. The light guide portion includes a first surface, a second surface which is parallel to the first surface, and a third surface which is positioned between the first surface and the second surface on another end side. A plurality of obliquely-inclined partial reflection surfaces are disposed between the first surface and the second surface, and the third surface is inclined in the same direction as that of the partial reflection surface. The third surface is configured with an anti-reflection surface for image light beams traveling through the light guide portion, and is covered by an anti-reflection film, a light absorption layer, a moth-eye type roughened surface, or the like. Therefore, occurrence of stray light due to reflection by the third surface can be suppressed.

Claim (Index 7):
The light guide device according to  claim 1 ,\n wherein the third surface is covered with an anti-reflection film.
