    摘要: An advantage of some aspects of the invention is to provide a virtual image display apparatus in which occurrence of luminance spots is suppressed to improve efficiency of use of illumination light. In the virtual image display apparatus of the invention, an optical-directivity changing section forms a non-uniform distribution concerning the directivity of image lights GL emitted from an image display device. Therefore, even when an angle of a light beam emitted from the image display device and effectively captured into the eye EY of an observer is substantially different depending on a position of the image display device, it is possible to form the image lights GL having directivity corresponding to such an angle characteristic of light beam capturing. It is possible to suppress occurrence of luminance spots to improve efficiency of use of illumination light.

    摘要: A support frame includes a light transmissive portion that is combined with a light guide member to form a see-through portion. The support frame assembled with the light guide member for image light observation therefore allows see-through observation of an outside-world object through the see-through portion. Further, providing the light transmissive portion in the support frame can increase the strength of the support frame while reducing the weight of the light guide member.

    摘要: In fabrication of a light guiding unit, a half mirror layer as a reflection film for folding light is covered by a light transmission main body part as a coating member, i.e., a light transmission member, and a hard coating layer is deposited thereon. Therefore, even when the surfaces of a light guide main body part and the light transmission main body part forming the light guiding unit are cleansed as pre-processing of the deposition of the hard coating layer, the situations such that the half mirror layer is separated thereby may be avoided and optical properties of the half mirror layer may not be lost.

    摘要: 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.

    摘要: 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.

    摘要: A virtual image display device has a light guide device in which the half mirror layer (the semi-transmissive reflecting film) of the light guide member is formed on the partial area of the first junction surface, and the second junction surface of the light transmitting member is bonded to the first junction surface in at least the exceptional area. Therefore, it is possible to increase the bonding strength of the first junction surface and the second junction surface, namely the strength of the light guide device composed of the light guide member and the light transmitting member combined with each other even in the case in which the attachment force of the half mirror layer (the semi-transmissive reflecting film) with respect to the first junction surface is not sufficiently strong.

    摘要: A thickness of a tapered part provided at the deeper side (−X side) in a light guide direction of a light transmission member is smaller toward the deeper side, and thus, a reflection angle of ghost light that has passed through a fourth reflection surface provided with a half mirror layer and reached the light transmission member gradually becomes smaller within the tapered part and no longer satisfies a total reflection condition, and the light is ejected to the outside in the position diverging from an eye of an observer. That is, the tapered part may prevent the ghost light from reaching the eye and good see-through observation can be realized.

    摘要: In regard to a second direction (combination direction) that is turned back by a reflection at the time of light-guiding, a projective optical system has an emission opening width larger than an opening width of a third reflective surface, such that it is possible to prevent a partial deficiency of image light when the image light emitted from the projective optical system is incident to the third reflective surface from occurring, and thereby it is possible to prevent the occurrence of deficiency of an image or a large variation in brightness.
