Abstract: PROBLEM TO BE SOLVED: To provide a virtual image display device that has a see-through function for superimposing external light and video light on each other to be displayed, has a wide field angle and high performance and yet is reduced in size and in weight.SOLUTION: In each display device of a virtual image display device, video light GL totally reflected by two surfaces or more in order of a third surface S43, a first surface S41 and a second surface S42 is transmitted through the first surface S41 and reaches an eye EY of an observer while an intermediate image is being formed inside a prism 40. Accordingly, display having a wide field angle, brightness and high performance can be realized while the prism 40 is being caused to be a thin-type and an entire optical system is being reduced in size and in weight. Further, external light HL, for example, can be transmitted through the first surface S41 and the third surface S43 and can be observed, and, in this case, a diopter scale is set to substantially 0. Therefore, defocusing and distortion of the external light HL that occur when the external light HL is observed by see-through can be reduced. Furthermore, a shape of each prism 40 is formed to the shape along a face of the observer, and a center of gravity of the virtual image display device is close to the face. The virtual image display device can be excellent in design.

Abstract: PROBLEM TO BE SOLVED: To provide a virtual image display device that is a see-through type for superimposing image light and external light and allows brightness of the image light to be appropriately adjusted in accordance with a state of the external light.SOLUTION: Light guide devices 20 serving as virtual image formation sections are see-through types for superimposing image light GL and external light OL. A controller 311 serving as an image light controller associates brightness of the external light OL with orientation, detects the brightness by a light detector 180 and controls the image light GL on the basis of information related to the brightness detected. Thus, the image light GL can be controlled corresponding to the brightness of the external light OL from face orientation of an observer, and a balance between brightness of an image by the image light GL and brightness of an external image by the external light OL can be made appropriate. More specifically, brightness of the image light GL can be appropriately adjusted in accordance with a state of the external light OL.

Abstract: PROBLEM TO BE SOLVED: To provide a virtual image display device that is a see-through type for superimposing image light and external light and allows adjustment in response to positions of eyes to be easily performed while suppressing an increase in size of the virtual image display device.SOLUTION: A wearer can perform adjustment of a position of a virtual image display device 100 with respect to positions of his or her own eyes EY by alignment mechanisms 300 while checking marker members MP1 that are positioning members. Accordingly, the wearer can easily set the position of the virtual image display device 100 to an optimum adjustment position. Further, the wearer can simply perform positional alignment in response to an individual difference in association with the positions of his or her own eyes EY. Therefore, it is unnecessary that light beams of image light GL are widened beforehand and are kept in a state with a margin so as to allow an image to be recognized by the wearer even when a certain degree of difference between the positions of his or her own eyes EY exists. On account of this, an increase in size of the virtual image display device 100 can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a virtual image display device capable of increasing a display size of a virtual image by a simple structure and of securing a large diameter of an eye ring, and further making excellent see-through observation possible.SOLUTION: Since a half mirror layer 28 has angle dependence, of which a reflectance ratio increases when an angle of incidence is greater than an incident angle range of image light GL, it is possible to prevent unintended light that is emitted from a light guiding member 21 to a light transmitting member 23 and is reflected in the light transmitting member 23 from passing through the half mirror layer 28 as a reflecting film with a relatively large incident angle and from being returned to a light emitting section B3 of the light guiding member 21. Therefore, it is possible to prevent the image light GL passing through the light transmitting member 23 from becoming ghost light GG and to make a virtual image displayed by a virtual image display device 100 high quality while alleviating a requirement for enhancing processing accuracy of the light transmitting member 23 and bonding accuracy between the light guiding member 21 and the light guiding member 23.

Abstract: PROBLEM TO BE SOLVED: To provide a virtual image display device which enables a see through observation while preventing ghost light from being observed.SOLUTION: A first surface 23a of a light transmission member 23 internally reflects image light GL having passed through a fourth reflection surface 21d and a transmission surface 23c toward outside of a region of the fourth reflection surface 21d. Consequently, for example the ghost light having passed through the fourth reflection surface 21d provided with a half mirror layer 28 and reached the light transmission member 23 is appropriately handled by the first surface 23a of the light transmission member 23, and is prevented from returning to a light guide member 21 and from entering into eyes EY of an observer. Thus, the ghost light is prevented from entering into the eyes EY by the first surface 23a of the light transmission member 23, so as to enable an excellent see-through observation.
