摘要： An image display device mounted on a head of an observer for use includes: a video light generation unit that generates video light modulated based on a video signal; a light scanner that is located on a lateral side of the head of the observer, performs main scanning on the video light in a first direction, and performs sub-scanning on the video light in a second direction orthogonal to the first direction; and a diffraction optical element on which the video light scanned by the light scanner is incident and which diffracts the incident video light and emits the video light toward one eye of the observer, wherein for the video light at an intersection point between a center of an amplitude of the main scanning and a center of an amplitude of the sub-scanning, a normal line at the intersection point of the surface of the diffraction optical element is inclined with respect to a virtual plane including a center of the one eye of the observer, a center of the other eye of the observer, and the intersection point so that light reflected from a surface of the diffraction optical element is not incident on the other eye of the observer.

摘要： There is provided an image display device with which it is possible to visually recognize an image while securing the see-through property regardless of eye movements and changes in interpupillary distance, with which it is possible to display a large-size image with high quality, and which is small, has excellent wearability, and has an excellent external appearance.
A display device 100 of the invention includes a light source optical system 15, a mirror 16 which reflects a light which is emitted from the light source optical system 15, a light scanning device 17 which scans the light which is reflected by the mirror 16, a pupil magnifying optical system 12 which magnifies a beam diameter of the light which is emitted from the light scanning device 17, a correcting optical system 13 on which the light which is emitted from the pupil magnifying optical system 12 is incident and which corrects an image which is generated at a position of an exit pupil G, and a holographic mirror 14 (a deflecting optical system) which deflects the light which is emitted from the correcting optical system 13 to guide the light to the position of the exit pupil G and transmits a portion of external light.
