Abstract: In an image generation unit, a light emitting part is formed using a self-emitting OLED device, and thereby, high-contrast images can be formed and the life of the light emitting part and the life of the virtual image display apparatus are extended. Even when the light emitted in the light emitting part has deviation in color balance, a half-mirror layer that has light transmissivity and realizes see-through vision is a reflection film having wavelength dependence, and thereby, a uniform color balance of image lights is achieved and images in good conditions are visually recognized.

Abstract: 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.

Abstract: A light guide member which guides video light includes a peripheral area forming portion extending to the outside of an effective light flux guide portion which is an area through which an effective light flux of the video light passes, and thus for example, even when ghost light resulting from components generated by unintended reflection or scattering in a position such as a side surface forming portion of the light guide member may be generated, the side surface forming portion can be separated from the effective light flux guide portion.

Abstract: A trapezoidal correction processing portion performs trapezoidal correction (distortion correction) on video image areas each of which is divided into a plurality of video image areas separately in accordance with the divided video image areas. In this case, each of the video image areas is divided into a plurality of areas. Further, a pair of right and left virtual image formation sections perform trapezoidal correction in a mirror symmetric manner, and the center position of the wearer's eye in each of the virtual image formation sections is so adjusted that the center position coincides with a distortion-free image corrected by using a small amount of correction.

Abstract: Image light is formed of light flux components having a diameter of, e.g., 3 mm or smaller. The image light is then caused to be incident on the iris of an eye to form an image in the form of a virtual image. The position where the principal rays of the light flux components that form the image light intersect one another is set to be a position shifted from the position of the iris of the eye toward the retina. The range of the light flux components that reach the retina can thus be changed in accordance with the motion of the eye. As a result, in accordance with a change in the line of sight that occurs when a wearer moves the line of sight in a specific direction, the image light can be so controlled that only image light components in the specific direction reach the retina of the eye.

Abstract: A wearer of a virtual image display apparatus can adjust the position of the virtual image display apparatus relative to the position of each of the wearer's eyes by using a registration mechanism while checking a marker member that is a positioning member, whereby an optimum adjusted position is readily achieved. Further, registration according to person-to-person differences in the position of each of the eyes can be readily achieved, whereby it is not necessary to increase the light flux width of image light in advance or provide the image light with a margin so that the wearer can recognize an image even when the position of the eye deviates from a normal position to some extent, and the size of the apparatus will not increase.
