Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A virtual image display device comprising: a signal-light modulating unit configured to emit a signal light modulated according to an image; a scanning optical system configured to scan the signal light made incident from the signal-light modulating unit and emit the signal light as scanning light; and a virtual-image forming member configured to receive irradiation of the scanning light from the scanning optical system and form a virtual image, wherein…
