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.
摘要翻译：本发明旨在提供一种虚拟图像显示装置，其能够在实现设计限制的同时将进入观察者的眼睛的图像光的纵横比设置为虚像而达到所需状态。在本发明中，由于宽高比转换光学系统中的转换，虚拟图像的宽高比可以横向比长度高于图像区域的纵横比（4:3）转换成纵横比（16：9）。因此，即使在例如图像形成装置的横向宽度相对于图像形成装置的横向宽度的情况下，也可以将由观察者的眼睛识别的图像光的纵横比调整为期望状态整个虚拟图像显示设备受到设计要求的限制。

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： 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.
摘要翻译：在透光构件的导光方向上设置在深侧（-X侧）的锥形部的厚度朝向较深侧较小，因此，已经穿过第四反射面的重影体的反射角设置有半透半反镜层并到达透光部件的部分在锥形部分内逐渐变小，不再满足全反射条件，并且在从观察者的眼睛偏离的位置将光弹出到外部。也就是说，锥形部分可以防止鬼影光到达眼睛，并且可以实现良好的透视观察。

摘要： Since a distance from an image extraction part to a light exiting surface is shorter downstream in an optical path than upstream in the optical path in relation to Z direction that is an arraying direction of reflection units, image light that propagates to pass between the image extraction part and the light exiting surface without becoming incident on the reflection units and therefore cannot be extracted to outside can be reduced. That is, since image light having a large total reflection angle in a light guide plate can be securely made incident on the image extraction part and efficiently extracted from the light exiting surface, light use efficiency in image formation can be enhanced. Thus, a virtual image display apparatus with brightness and high performance can be provided.
摘要翻译：由于从图像提取部到光出射面的距离相对于作为反射单元的排列方向的Z方向的光路的上游在光路的下游较短，所以在图像提取之间传播的图像光部分和光出射表面而不会入射到反射单元上，因此不能将其提取到外部。也就是说，由于导光板中具有大的全反射角的图像光可以牢固地入射到图像提取部分上并且有效地从光出射表面提取，因此可以提高图像形成中的光利用效率。因此，可以提供具有亮度和高性能的虚像显示装置。

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： 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。

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.
