The image light entering the image take-out section is reflected by the first reflecting surface and the second reflecting surface in a two-stage manner. It is not only possible to make the light beam with a small total reflection angle out of the image light directly enter the side near to the light entrance section out of each of the reflecting units, but also to make the light beam with a large total reflection angle directly enter the side far from the light entrance section out of each of the reflecting units to thereby make it possible to take out the image light to the outside. Therefore, the image light is emitted as the effective virtual image light for the observer in the condition in which the brightness variation and the picture variation are prevented and a high light efficiency can be obtained.
