摘要： An image display device is a self-luminous type device including a light emitting portion, and a casing portion of a display device unit has a heat dissipating structure portion through which a part of the image display device is exposed for heat dissipation. In manufacturing the display device unit, when performing simple and reliable assembly while securing a high heat dissipation characteristic, for example, by using characteristics of a silicon substrate, high accurate positioning is performed in a display device positioning portion.

摘要： In first and second display devices that are provided in a pair on the left and right sides, image light and external light are superimposed on each other and viewed. In this case, a parallax of an angle (the value of angle) is set by a frame unit functioning as a parallax setting unit tilting principal rays of left and right image light inwardly, and the angle of convergence of an observer is in an appropriate state in the case of viewing the image light.

摘要： In a light guide device, a step between optical surfaces connected to each other by a connection portion can be limited to 1 mm or smaller so that a large stepped portion is not allowed to be formed at the connection portion in a hard coat formation process, whereby a coating liquid that flows along portions that are to form the optical surfaces forms no liquid pool or causes no liquid sagging. The light guide device can thus maintain satisfactory light guiding performance at the light guide portion.
摘要翻译：在导光装置中，通过连接部彼此连接的光学面之间的台阶可以限制在1mm以下，使得在硬涂层形成工序中不能在连接部形成大的台阶部，由此沿着形成光学表面的部分流动的涂布液不会形成液体池，也不会形成液体下垂。因此，导光装置能够在导光部保持良好的导光性能。

摘要： With respect to an emitting side optical axis, which is an optical axis on a first surface, a sight line reference axis which is assumed as a sight line axis of the eyes of an observer extends in a slightly inclined direction. In particular, the emitting side optical axis with respect to the sight line reference axis is configured to approach the eyes from the outside (that is, a corner of the eyes) of the eyes. In addition, a long image in a vertical direction which is perpendicular to an alignment of the eyes rather than in the horizontal direction which corresponds to the alignment of the eyes, is displayed.

摘要： A light guide member includes a plurality of non-axisymmetric curved surfaces, whereby a wide viewing angle and reduction in size and weight are achieved as the whole apparatus. A curved surface is formed such that a blur amount of video light on a position of an image surface of an intermediate image is greater (for example, greater than 10 times a blur amount on a position of an image surface of a video element). With this, even when there is a scratch, dust, or stain on the surface of the light guide member near the intermediate image or there is a contaminant or air bubble inside the light guide member, a situation in which the scratch or the like is enlarged and noticeable to degrade video quality is avoided, and high performance is achieved.
摘要翻译：导光构件包括多个非轴对称曲面，由此可以实现整个设备的广视角和尺寸和重量的减小。形成弯曲表面，使得中间图像的图像表面的位置上的视频光的模糊量更大（例如，大于视频元素的图像表面的位置上的模糊量的10倍）。因此，即使在中间图像附近的导光部件的表面上存在划痕，灰尘或污渍，或者在导光部件内部存在污染物或气泡，则划痕或类似现象的情况避免了放大和显着降低视频质量，实现了高性能。

摘要： A light blocking member that is a light blocking structure disposed in an exit pupil position can remove in advance a light component of video image light that undergoes unintended reflection to avoid generation of ghost light and allows formation of a satisfactory image. Further, a projection lens and other components form an intermediate image in a prism, and the video image light totally reflected off at least two surfaces of the prism, a third surface, a first surface, and a second surface in this order, passes through the first surface and reaches an eye of a viewer, whereby the prism can be thin and the overall optical system can be compact and lightweight and provide wide angle, bright, high-performance display.

摘要： A light emitting device, which is a main body, is arranged to be located closer to the nose NS side than the eye EY of a wearer during wearing of a virtual image display device. Therefore, the light emitting device is prevented from excessively projecting to the side of the face of the wearer. The light emitting device is arranged between the eye EY of the wearer and the virtual-image forming member. Therefore, the light emitting device is prevented from excessively projecting further to the front side than the virtual image forming member, i.e., the front side of the face of the wearer. Further, a combined-light forming unit is a unit small in size and light in weight. Therefore, it is possible to suppress the center of gravity of the entire virtual image forming member from deviating to the side and the front side.

摘要： A see-through display apparatus includes an image display apparatus configured to emit a video light, a light guide apparatus configured to guide the video light and to output the video light in a first direction, and a light control shade disposed opposite to the first direction with respect to the light guide apparatus. The light control shade is configured to control a transmittance of an outside light based on a luminance of the outside light. A first response time of the light control shade when the outside light changes from a lower luminance to a higher luminance is slower than a second response time of the light control shade when the outside light changes from the higher luminance to the lower luminance.

摘要： A light guide device that does not cause non-uniformity in image light and external light and does not cause ghosts, and a virtual image display apparatus provided with the light guide device. The light guide device includes a parallel light guide, an incident section, and an emission section. Here, the light guide device is set such that image light rays are reflected without reflecting from a boundary surface between the parallel light guide and the reflection unit and head for an observer. Thus, the image light rays only pass through half mirrors, which are positioned in positions where the image light rays are emitted from the reflection unit of the emission section or are positioned therearound. Accordingly, it is possible to prevent luminance non-uniformity or light reduction by reducing the number of times of the image light rays to be observed pass through the half mirrors.

摘要： In a projection system, providing a stop that forms an opening that is symmetric with respect to a first flat plane including the projection system optical axis and a first axis that extends in parallel to the first direction and intersects the projection system optical axis but asymmetric with respect to a second flat surface including the projection system optical axis and a second axis that extends in parallel to the second direction and intersects the projection system optical axis allows appropriate light adjustment at the stop even when pencils of light from the points in a video device exit at different angles along a second direction, whereby high-quality video images can be provided with the size of an optical system further reduced and therefore the size of an overall virtual image display apparatus reduced.
