Claim 0:
1. A virtual image display apparatus comprising:
an imaging light emitting device configured to include a display portion emitting imaging light, and
an optical unit configured to guide the imaging light emitted from the imaging light emitting device,
wherein
the display portion has a first region and a second region, the first region according to a distortion generated in the optical unit, a number of pixels in the first region being different from a number of pixels in the second region,
the optical unit includes a projection optical system, a turning mirror, a transmission mirror, and a concave mirror,
the projection optical system projects the imaging light emitted from the imaging light emitting device,
the turning mirror reflects the imaging light to a direction crossing with the imaging light from the projection optical system,
the transmission mirror reflects a part of the imaging light from the turning mirror and transmits other part of the imaging light, and
the concave mirror has a concave shape and reflects toward the transmission mirror, the imaging light reflected by the transmission mirror, thereby forming an exit pupil.
