The sizes of the respective reflecting units vary in the image take-out section along the Z direction in association with the state of the total reflection angle in the light guide section. Thus, it becomes possible to keep the sufficient effective light beam width of the image light input thereto in all of the reflecting units. Therefore, the deterioration in the image light caused by the reflection in the reflecting units can be avoided, and as a result, the degradation of the resolution of the image due to the virtual image light thus emitted can be prevented. |
