Abstract
An image light generation device generating image light, a semi-transmissive tilted mirror reflecting the image light from the image light generation device, and a concave semi-transmissive mirror reflecting, toward the semi-transmissive tilted mirror, the image light reflected by the semi-transmissive tilted mirror to form an exit pupil are provided, and the concave semi-transmissive mirror includes a partial reflective film having different reflectance according to wavelength, the semi-transmissive tilted mirror reflects the image light toward the partial reflective film.

A virtual image display device comprising:
- an image light generation device generating image light;
- a first mirror reflecting the image light from the image light generation device;
- and
- a second mirror having a concave shape and reflecting, toward the first mirror, the image light reflected by the first mirror,
- wherein the second mirror includes a first reflective film on which the image light reflected by the first mirror is incident, the first reflective film has different reflectance according to wavelength.
An optical unit comprising:
- a first mirror reflecting an image light;
- and
- a second mirror having a concave shape and reflecting, toward the first mirror, the image light reflected by the first mirror,
- wherein the second mirror includes a reflective film on which the image light reflected by the first mirror is incident, the first reflective film has different reflectance according to wavelength.
