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： Image light reflected by a third reflective surface of a light incidence portion is propagated while being totally reflected by first and second reflective surfaces of a light guiding portion, is reflected by a fourth reflective surface of a light emission portion, and is incident to observer's eye as a virtual image. At this time, the number of times of reflection of first image light, which is emitted from a first partial region of an image display device, in the light guiding portion, and the number of times of reflection of second image light, which is emitted from a second partial region of the image display device in the light guiding portion are different from each other, such that it is possible to take in the image light beams from the different partial regions of the image display device with a relatively wide angle of view.

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.

摘要： The invention is directed to provide a virtual image display device capable of setting the aspect ratio of the image light entering the eyes of the observer as a virtual image to a desired state while fulfilling the design limitations. In the invention, the aspect ratio of the virtual image can be converted to the aspect ratio (16:9) laterally longer than the aspect ratio (4:3) of the image area due to the conversion in the aspect ratio conversion optical system. Thus, the aspect ratio of the image light to be recognized by the eye of the observer as a virtual image can be adjusted to a desired state even in the case in which, for example, the lateral width of the image forming device with respect to the whole of the virtual image display device is limited by a design requirement.

摘要： An image relay optical system is provided with an optical coupling member before incidence of image light on a light guide member. Among a first light incident surface, a coupling member reflecting surface, and a first light emitting surface provided in the optical coupling member, the coupling member reflecting surface and the first light emitting surface are curved surfaces. Therefore, a large bright virtual image with reduced aberration can be displayed.

摘要： A half mirror layer has an angle dependency in which when an angle of incidence becomes larger than the angle of incidence range of image light, reflectance increases, such that it is possible to prevent unintended light, which is emitted to a light transmitting member from a light guiding member and is reflected inside a light transmitting member, from being returned to a light emission portion of the light guiding member after passing through the half mirror layer as a reflective film at a relatively large angle of incidence. Therefore, it is possible to prevent the image light passed through the light transmitting member from becoming ghost light while mitigating the demand for increasing processing accuracy of the light transmitting member, and bonding accuracy between the light guiding member and the light transmitting member.

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： 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： 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： 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.
