An image display includes polarization axis control means for separating light irradiated from a light source into light having a first polarization axis and another light having a second polarization axis different from the first polarization axis and a lens advancing the light having the first polarization axis and the light having the second polarization axis separated by the polarization axis control portion to have different polarization axes in prescribed directions respectively and including at least one lens portion formed to extend in a first direction intersecting with a line segment connecting the left and right eyes of an observer with each other.
