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： 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： 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 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.

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： In a virtual image display device, a mirror layer has a thickness of 50 nm or more to perform non-transparent reflection in a second ridge line vicinity area on a third reflection face side in a ridge line portion extending between the third reflection face and a second reflection face. Accordingly, reflectance of image light can be prevented from being decreased by the second ridge line vicinity area (that is, a peripheral portion on a light guide unit in the third reflection face), and thus stripe-shaped brightness unevenness extending in a longitudinal direction can be prevented from occurring on the viewed image. That is, in the image display device, it is possible to secure sufficient reflection even in the peripheral portion close to a boundary with the second reflection face with respect to the third reflection face, and also to display a bright image with little brightness unevenness.
摘要翻译：在虚像显示装置中，镜层的厚度为50nm以上，在第3反射面和第3反射面之间延伸的棱线部分的第3反射面侧的第2脊线附近区域进行非透明反射第二反射面。因此，可以防止图像光的反射率被第二脊线附近区域（即，第三反射面中的导光单元的周边部分）减小，并且因此在纵向方向上延伸的条形亮度不均匀可以防止在观看图像上发生。也就是说，在图像显示装置中，即使在靠近与第二反射面相对于第三反射面的边界的周边部分中也可以确保足够的反射，并且还可以显示亮度不均匀的亮度图像。
