Abstract

A display device for displaying a floating aerial image using retroreflection includes a light source, a beam splitter, at least first and second retroreflection members disposed along different planes, and at least first and second phase plates disposed on respective surfaces of the first retroreflection member and the second retroreflection member, wherein the beam splitter is configured to reflect light from the light source to the first and second retroreflection members, and to transmit light reflected by the first and second retroreflection members so as to form the floating aerial image, and a slow axis of the first phase plate has an angle difference with respect to a slow axis of the second phase plate such that a difference between a phase difference of the light transmitted through the first phase plate and a phase difference of the light transmitted through the second phase plate becomes small.
