A wavelength separation device includes a waveplate adapted to convert the polarization direction of light in a predetermined wavelength band so that right-eye and left-eye image light in a time-divisional manner can be separated into first outgoing light as first polarized light in a first wavelength band and second outgoing light as second polarized light in a second wavelength band, a polarization control element adapted to keep the polarization direction of the first and the second outgoing light input from the waveplate in the case of either one of the right-eye and the left-eye image light, and respectively change the polarization direction of the first and the second outgoing light input from the waveplate in the case of the other thereof, and a polarization plate adapted to absorb one of the first polarized light and the second polarized light, and transmit the other thereof. |
