Abstract

According to one embodiment, a display apparatus projects a light flux including image information toward one eye. The apparatus includes an image formation unit and a projection unit. The image formation unit is configured to emit the light flux. The projection unit includes a projection region limiting unit and a semi-transmissive reflective unit. The projection region limiting unit is configured to limit a width of the light flux emitted from the image formation unit. The semi-transmissive reflective unit is configured to reflect the light flux emitted from the projection region limiting unit. A distance between the semi-transmissive reflective unit and an imaging plane of the light flux is not more than 250 mm.
