Beschreibung
Zusammenfassung:	An object is to provide an eye gaze tracking system capable of easily detecting an eye gaze, and a virtual image display device using the same. The object is achieved by providing an infrared light source array, a virtual image generation optical system, and an infrared light detector, and by sequentially turning on infrared light sources of the infrared light source array, collimating rays of infrared light through the virtual image generation optical system, making the collimated rays of infrared light incident on a user's eye at different angles, respectively, and detecting, among the rays of infrared light incident on the eye, a ray of infrared light incident on a retina through a pupil and reflected by the retina through the infrared light detector.
