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 1):
A light guide device comprising:\n a transparent light guide portion that guides light beams incident from one end side to a light-emitting portion, wherein the light guide portion includes\n a first surface that extends from the one end side on which the light beams are incident toward another end side in a first direction, \n a second surface that extends in the first direction and in parallel to the first surface in one side of a second direction intersecting with the first direction, \n a third surface that is positioned between the first surface and the second surface at the another end side of the light guide portion, and \n a plurality of partial reflection surfaces that are disposed along the first direction between the first surface and the second surface and are inclined at the same angle from a normal direction with respect to the second surface toward the one end side when viewed from a third direction intersecting with the first direction and the second direction, and \n wherein the third surface is a surface with an anti-reflection structure.
