Abstract

A display device includes an image display element, a collimator, a first light guide formed of a flat plate transparent to light, a second light guide formed of a plate member transparent to the light and having one surface that is a flat surface in contact with one of surfaces of the first light guide and the other surface that is a sawtooth surface, and a beam splitter formed on an interface between the first and second light guides to transmit a part of the light and reflect the remainder thereof. The sawtooth surface is configured by alternately combining a first surface non-parallel to a propagating direction of the light propagating through the second light guide after passing through the interface and configured to transmit the light and a second surface substantially parallel to the propagating direction.
