摘要：
This invention provides an off-axis type hologram lens and a display apparatus using the same, which can satisfactorily correct aberrations caused by an off-axis arrangement of a hologram lens and an eclipse of a displayed image by a pupil of an observer by properly setting an arrangement of the off-axis type hologram lens, so that image information from an image display and another image information are spatially superposed on each other, and the superposed images can be observed in an observation field at a uniform brightness.
